You read that right! I've managed to port PPSieve-CUDA to OpenCL and compile it with the ATI compiler!

The code base is very similar to PPSieve-CUDA, and will eventually be merged with it. But for now, if you have Linux and an ATI GPU, please download:

PPSieve-OpenCL (source, on the redcl branch)

And give it a shot with the usual test procedure:

32 bit: ./ppsieve-cl-boinc-x86-linux -p42070e9 -P42070010e6 -k 1201 -K 9999 -N 2000000 -c 60
64 bit: ./ppsieve-cl-boinc-x86_64-linux -p42070e9 -P42070010e6 -k 1201 -K 9999 -N 2000000 -c 60

It should output the following factors:

42070000070587 | 9475*2^197534+1
42070000198537 | 3373*2^1046686+1
42070003101727 | 4207*2^1054290+1
42070003511309 | 6057*2^1043547+1
42070006307657 | 1513*2^1771812+1
42070006388603 | 2059*2^1816098+1
42070007177519 | 5437*2^1121592+1
42070007396759 | 7339*2^1803518+1
42070008823897 | 4639*2^952018+1
42070008858187 | 2893*2^317690+1

Please provide the output from stderr.txt, especially in case of error. Please also provide as much detail about your system as possible, including your ATI GPU model number, driver version, and Stream Processing Unit clock speed if possible.

Also note that this first version doesn't use vectorized arithmetic, so it may be possible to make it ~1.5-2x faster. The first goal is to prove that this can run on an ATI GPU. :)

I entered this into the command line:

./ppsieve-cl-boinc-x86_64-linux -p42070e9 -P42070010e6 -k 1201 -K 9999 -N 2000000 -c 60

And got this:
./ppsieve-cl-boinc-x86_64-linux: error while loading shared libraries: libOpenCL.so: cannot open shared object file: No such file or directory

No stderr.txt file was created.

I was using my ATI Mobility Radion 4650. I think that the driver version was 10.8
This was running off of my jumpdrive, using Ubuntu 10.04

I must say that being unfamiliar with Linux and running on an 8GB jumpdrive is causing me problems trying to test this.

I'm not sure how much work is required to set up for running an OpenCL app. That's part of what I'm testing here.

I downloaded the ATI Stream SDK from here and went through this installation procedure (PDF). I'm hoping the full installation isn't necessary, and that you only need to grab the lib/x86/libOpenCL.so or lib/x86_64/libOpenCL.so file and put it in the same directory with my app. But I really don't know.

Edit: Also, the Stream SDK version was 2.1 when I downloaded it, and that's what I used to compile this, but they're serving 2.2 now. Hopefully, that won't make a difference.

O.K., I tested it again, with the libOpenCl.so from SDK V2.2. I get the same message:

./ppsieve-cl-boinc-x86_64-linux: error while loading shared libraries: libOpenCL.so: cannot open shared object file: No such file or directory

Is it expecting the file to be in a location other than where it launches from?

Linux search in the libarypath.
Have you set the 2 Variables from the instruction?
If not copy or link the lib to /usr/lib/ or set the 2 variables.
After that you can test with ldd:

ldd ppsieve-cl-boinc-x86_64-linux
linux-vdso.so.1 => (0x00007fff4e9ff000)
libOpenCL.so => /home/tocx/download/ati-stream-sdk-v2.2-lnx64/lib/x86_64/libOpenCL.so (0x00007f32533f9000)
libpthread.so.0 => /lib/libpthread.so.0 (0x00007f32531d1000)
libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0x00007f3252ebc000)
libm.so.6 => /lib/libm.so.6 (0x00007f3252c3a000)
libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x00007f3252a24000)

Looks like you'll (both/all) have to follow this entire installation procedure.

Don't forget to get this ICD registration file and extract it in the root directory, as root.

Looks like it was using your CPU, not your GPU. Probably because you're using an AMD processor. Try adding a "--device 1" to the end of the command line.

So, out of curiosity, why is Linux the first platform to test an application on?

I would like to help test this ATI app, but right now I simply do not know enough Linux to actively do so. I am afraid that I must wait for a windows testing app, or learn a lot about Linux.

By the way, thanks Ken (and anyone else involved) for starting ATI development!

Because this is my main computer. No other reason.

Well, I'm stumped. A segfault is hard enough to debug when you do have access to the hardware it happens on. Since it doesn't happen on a CPU, I don't.

I was hoping that someone would come along with an Intel processor and AMD graphics card, run the test, and find that it worked fine there. Since that hasn't happened, I've uploaded more-or-less the same code compiled with debugging on. If that doesn't produce a useful error message, I'm afraid ATI/OpenCL is at a standstill for now.

Yeah, OK, it'll probably be easier to build a Windows version than to teach all of you how to use Linux. I'm working on it.

Alright, folks, I stuck a Windows executable in that zipfile. It works on my CPU, but I kind of expect it will also segfault on a real GPU.

But test away; maybe we'll get lucky somewhere.

Since it's OpenCL, is this supposed to work on NVIDIA also?

No; nVIDIA already has a version specifically made for it. You can try compiling it for nVIDIA if you want, but it's not likely to be faster than the CUDA version.

Scott, did you install the ATI Stream SDK? I think you have to do that. I haven't yet seen a way to run this app without the full installation.

Figured that out after I posted :)

After the install, this is what I get:

ppsieve-cl-x86-windows.exe -p42070e9 -P42070010e6 -k 1201 -K 9999 -N 2000000 -c 60 --device 2
ppsieve version cuda-0.1.5a (testing)
nstart=76, nstep=32, gpu_nstep=32
ppsieve initialized: 1201 <= k <= 9999, 76 <= n < 2000000
Sieve started: 42070000000000 <= p < 42070010000000
Thread 0 starting


Then the app crashes with no log file or factors found. (*note: device 0 = AMD cpu, device 1 = onboard AMD GPU - not OPENCL compatible). The application does run fine on the cpu.

this is my experience.

download zip file. extract and run ppsieve-cl-x86-windows.exe

problem. 1) get pop-up, "Unable to locate OpenCL.dll"
answer: download and install ATI SDK

problem 2) running gives "unable to determing platforms" or similar message on console
answer: reboot machine (oops)

it then an successfully.. (however i dont have a GPU.. its an intel GMA )

so here are my CPU opencl results.

FYI, I've been looking at the kernel with the Stream Kernel Analyzer, and it looks like the current configuration (that writes bytes as output) won't compile on 4000-series GPUs. I'll look at changing this soon, but it would be nice if someone with a 5000 series produced valid results with this.

Edit: And I see tocx has a 5000 series, so that's not likely.

About 96% load on the ATI GPU, correct results. :)

Can't get it to run on the GTX460, but we have the CUDA app for that one, so it's no problem.

YES!!!!!!!!!! :D

I'm guessing tocx just needed me to compile with the sdk 2.2 instead of 2.1. :)

The error building program on a 4000-series processor is expected for now; I'll fix it soon. But this also points out another bug: multiprocessor counts are 16 times as large as they're being detected. I'll have to overhaul the device detection code.

Try installing the 32-bit version of the Microsoft Visual C++ 2008 redistributable package.

P.S. Please also use code tags judiciously. When text inside them is too long, they make the forum overflow my screen to the right.

Try installing the 32-bit version of the Microsoft Visual C++ 2008 redistributable package.

Thanks it helped.

Alright, I have a new test version ready for everyone, v0.0.2 alpha. This version is vectorized, so it could be up to twice as fast as the last version; though I'm suspecting it might be slower than the last version. Should that be the case, I have a version with no vectorization ready to go as well.

Vectorization is controlled with the -v parameter, so please try -v 2, -v 4, and maybe -v 3 (though that's likely to be really slow!). The default is 4.

Also, this code should now run on 4xxx series cards, though I will need comparisons to previous runs on 5xxx cards as well.

Good luck!

P.S. Gerrit, I hope your card gets well soon.

Hm, yeah, I probably should take the -g out at this point...OK, done!

Edit: In any case, you'd probably need to compile with nVIDIA's compiler to get this to work on nVIDIA.

Huh. OK, I guess I'll go with -v 2 unless someone who ran the earlier app finds this one slower.

Heh. I was right, though, -v 3 was much slower. :P

I get a driver crash, followed by the application running, but it is incredibly slow...while writing this message it has gotten just over 10% done.

Also, the SPUs are incorrect. A 4650 card has 320, not 640 as the app reports.


Edit: Also, I am wondering at the full core of CPU usage...maybe because this is an AMD CPU (Athlon x2 5600+)?

That's using your CPU. Try --device 1. Sorry I can't edit the first post to suggest that.

Also note that two cards in SLI are still two cards, and will probably be referenced separately, as --device 1 and --device 2.

Scott, I'm wondering about that too, but I doubt the CPU is the problem. Try --device 2 and --device 3 just to make sure, though.

Scott, I'm wondering about that too, but I doubt the CPU is the problem. Try --device 2 and --device 3 just to make sure, though.


--device 2 is the onboard graphics being used in tandem with the 4650 via the "surround view" feature...allows it to crunch over at Collatz, but is not OpenCL capable (app crashes as expected)

--device 0 runs the CPU...99% on the task manager and runs much slower than the 4650. Also shows up as 160 SPUs.

OK, a new version, 0.1.0-beta, is out. Major changes you should notice:

- It only runs on GPUs. So you shouldn't need to pass --device anymore unless you have two or more.
- It defaults to -v 2. So you shouldn't need to pass that anymore either.

So this should make it possible to run the app on BOINC PPSE WUs, with an appropriate app_info.xml file. (No, I don't know how to create one.)

Other things you might find interesting:
- -m works now. Default is 7, but you can fiddle to your heart's content. Not that I expect any significant improvements, but I've been wrong before.
- Better error messages. Not that you should notice.

Based on the number of crashes I saw from the previous version, I'm not sure any OpenCL app can come out of beta yet. But hopefully this is as stable as it can be. If you see any major issues, post them here.

Oh, and Scott, I have no answers for you about the 100% CPU usage on the 4650. I can only guess that either some driver is too old or it's a quirky card. I will say that I'm glad I didn't buy one. (I was thinking about it!)

I will try the driver when I am in the office tomorrow...might be the difference between 10.7 vs. 10.8 since I do not have the CPU load with 10.8 on my home machine with a 4670 card (results below). Also, you can see from the results below that the m setting of 7 is not optimal at least for this card.

Thanks, Scott! I now see that makes sense. I now have no idea where I got the 7, but searching for it I ran across this PDF. My "BLOCKSIZE" (which doesn't mean much in OpenCL except that it's a constant) is 128. That happens to be the right number of threads to fill a pair of wavefronts. Apparently four wavefronts avoid latency issues, so it makes sense that even m's would be better.

Now, no offense, Scott, but I'm not going to optimize for your low-end GPU specifically. But if I can get some tests of higher-end GPUs verifying this (and I expect I will), I'll release a version where m defaults to 2 tomorrow.

P.S. Anyone want to try -v 4 with -m 2? I doubt it will help, but like I said, I've been wrong before.

Also tried m 5, 6, 9, 10 and some numbers above 32, but they all were slower that the default.

@tepek: Your app_info works, but you don't need to include the file_info for pps_sr2sieve_20090322.sieveinput, as ppsieve doesn't need the sievefile.

Now, no offense, Scott, but I'm not going to optimize for your low-end GPU specifically. But if I can get some tests of higher-end GPUs verifying this (and I expect I will), I'll release a version where m defaults to 2 tomorrow.


None taken...the 4600 series is mid-range usually, but since OpenCL only runs on 4xxx and 5xxx cards, the low-end designation is appropriate.

Also, I figured out the issue on the 4650 card with CPU utilization of one full core. Turns out it wasn't the driver or quirky card, rather a quirky set-up. I had "surround view" turned on with a dummy plug to allow the onboard graphics to crunch along side the 4650 on Collatz (AMD 760 chipset, so not OpenCL capable). When I turn that off, the cpu load during sieve is about the same as the 4670 in my home machine with GPU times just a few seconds slower (as expected given the slower core clocks). I have not been able to find any info about the "Surround View" feature with OpenCL, so maybe this is a new issue that should be reported to AMD/ATI?


P.S. Anyone want to try -v 4 with -m 2? I doubt it will help, but like I said, I've been wrong before.


The -m2 setting remains the fastest for the 4600 series (I also tested m16, m32, and m64, each larger m being faster, but not as fast as the m2 setting). As before, the -v4 setting crashes the driver on the 4600 series.

Thanks, Scott! I now see that makes sense. I now have no idea where I got the 7, but searching for it I ran across this PDF. My "BLOCKSIZE" (which doesn't mean much in OpenCL except that it's a constant) is 128. That happens to be the right number of threads to fill a pair of wavefronts. Apparently four wavefronts avoid latency issues, so it makes sense that even m's would be better.


I wonder if the different -m performance across the cards so far is related to ATI employing different wavefront sizes in different cards? The 58xx/57xx and 48xx use 64, but a 5450 card has wavefront size of 32 (I haven't found the size for the 4650 yet...some cards are also have wavefronts of size 16, but I don't think any of these are OpenCL capable???).

@Elgrande71: A computation error means just that: your GPU found a factor that your CPU couldn't verify. Usually, this means you've overclocked too much!

By the way, for PPSieve, there's not much reason to overclock the memory, if such things are separate in ATI like they are in nVIDIA. You can under-clock the memory, overclock the shaders, and get better performance (as long as you don't overclock too much).

Nice! I didn't know about that. Now everyone can adjust their client manually as needed. :)

As for automatically finding a good setting, I'm not sure about that yet. :/ But it does look like -v 4 is best forgotten.

My GPU cards are a bit overclocked (Sapphire HD5870 Vapor-X) but now, there is no problem at all.
First WUs are gone in errors but now everything is working fine.
Thank you for your advice and your work.
Continue.

Yes, all three sizes are possible. And it seems to be hard to figure out which is which. That's what's stopping me from changing the default -m size right now.

About computation errors, note that most computation errors go undetected. Especially the important ones, where a factor is missed. So if you're getting detected computation errors, even if they stop, it would be a good idea to change something to prevent future errors.

Alright, I've pushed a new version that just changes the default -m to match what CL_KERNEL_WORK_GROUP_SIZE returns. It's so similar that I didn't even bother changing the version number. (But the build date is today.) It also prevents using a -m higher than the default, as I think it returns a maximum.

Since the default is now the maximum possible size, I'd like to see what various cards set -m to on the test run. (It's printed to stdout.) It might make sense to make the default -m some fraction of what it is now. So let me know what your cards produce.

Thanks!

Jip, did you complete all of the installation procedure (PDF), including setting up all necessary environment variables?

Vato: I'm afraid I don't have any personal experience with cards being found. (Since I don't have one. :P)

I think you need the complete SDK install because the OpenCL code is distributed as source code. The OpenCL SDK has to compile it, every time, before it can run!

I am aware that the current SDK allows compiling in binary OpenCL code; however, the app is currently set up to "bake in" certain constants.

Have now put 32bit and 64bit SDK libs in /lib32 and /lib64 respectively, re-run ldconfig, downloaded latest ppsieve-cl.zip, tried boinc and non-boinc and 32bit and 64bit executables - and still haven't got very far. Running under strace just shows lots of mmap() calls succeeding prior to calling clone() and futex(). Still HD4670 Ubuntu 10.04 x86_64 - any further hints gratefully received.

Message 26373 - Posted: 14 Sep 2010 | 7:36:04 UTC

After several tests with my system ( Q6600 4Go Ram, 2x ATI HD5870 Crossfire), it seems that the m parameter doesn't have to exceed 24 otherwise one of my GPU send out compute errors.
With m equal to 32, the only GPU which doesn't provide with compute errors calculates workunits in 6min30s instead of 7min30s. It's a shame that the second GPU doesn't calculate workunits without errors.
I tried to find a fix for this but no luck (driver, etc....) .
Futhermore, I upgraded Boinc to the 6.10.58 version but nothing changes.

Don't hesitate to put another version of your app for testing.

you have to disable crossfire to make the second gpu working in opencl. It's a long standing bug, fortunately now solved for "old" Brook/CAL apps but still not for OpenCL/CAL apps.

It's a big problem for people with a 5970, because you cannot disable crossfire on that graphic card and so you're forced to use only one gpu.

It's not a problem of this app, it's a problem of both driver (10.7b, 10.8 & 10.9) and AMD SDK 2.2

I have to summarize my situation :
without crossfire only one GPU is detected by Boinc
with crossfire two GPU detected by Boinc
All other configurations have been tested without success.
GPU workunits computation errors only occured if m parameter is equal or higher than 32 and only one GPU is concerned (not the other).
Is it clear ?
Ati (Amd) developpers have to fix their drivers and SDK.

I told you that the "second" gpu often makes computational errors with crossfire enabled. This is a problem with SDK 2.2 and AMD drivers. They'll fix this, eventually, with the following 2.3 release.

You can do two things:

- disable crossfire (you can, you do not have a 5970 in which you can't) and make boinc able to find the second gpu using a dummy plug and extending the desktop (search for this procedure on google) to the secondary fake monitor

- leave crossfire enabled and crunch only on one gpu, the first one.

If not, you'll have to live with the 2nd gpu making a lot of computational errors until the next sdk

A complete work unit on the HD 4770 @ stock clock needs less time (45 seconds faster) than on my overclocked GTX 260-192 @ 667 MHz.
If I overclock the HD 4770 too it is up to 160 seconds faster than the already overclocked GTX.

An additional note:

The Windows GUI is much more responsive if I crunch PPS sieve WU's on the ATI instead of using the CUDA enabled GTX.

That's not much detail. I infer from the 800 SPUs that this is a 5770. Is it overclocked at all? (Edit: since it might be overclocked at the factory, can you determine its clock speed?)

Does that help ??

That's a little helpful, but not my main focus right now. Right now I'd like to get the new algorithms tested in the CUDA thread. Then I can port them here and you can help me test that.

Yes it is indeed a 5770 ! I think was running @ 800Mhz

That's a little helpful, but not my main focus right now. Right now I'd like to get the new algorithms tested in the CUDA thread. Then I can port them here and you can help me test that.

OK will be glad any time to help .. just let me know what to do

Alright, everybody, I finally have a new version of PPSieve-CL! V0.2.0-beta incorporates the algorithms of the CUDA version 0.2.1a. Get it at the usual place. Windows builds included too!

Now, to testing! Please test:


  1. The usual range
  2. -p20070e9 -P20070010e6 -k 1201 -K 9999 -N 2000000 -c 60
    That should produce:
    20070000475957 | 4995*2^1822738+1
    20070001146497 | 4977*2^626298+1
    20070001163929 | 3765*2^461308+1
    20070001302811 | 7669*2^725426+1
    20070001425977 | 5821*2^1775248+1
    20070002245151 | 1221*2^646983+1
    20070002606341 | 4809*2^497683+1
    20070004816819 | 6699*2^1215561+1
    20070005914001 | 9847*2^1634140+1

    20070008329039 | 9065*2^832569+1
    Found 13 factors

  3. -p20070e9 -P20070010e6 -k 1201 -K 9999 -N 2000000 -c 60 -R
    The reasons for this should quickly become obvious if they aren't already. That should produce:
    20070000541441 | 3243*2^1584966-1
    20070000674041 | 8143*2^1397047-1

    20070002680493 | 6455*2^1778260-1
    20070003067151 | 9259*2^1869285-1
    20070004606567 | 5269*2^257879-1
    20070005404357 | 7893*2^796719-1
    20070006186677 | 2413*2^1924519-1
    20070007049707 | 2149*2^153375-1
    20070007529777 | 1367*2^1532230-1
    20070008213771 | 4041*2^1187467-1
    20070008917537 | 6671*2^1260830-1
    20070008991223 | 5523*2^101606-1
    Found 14 factors



And let me know how fast it goes too! (Speed is printed in stderr.txt when using the BOINC apps.)

Thanks!

It's just infuriating running collatz instead of sieving.

Vato, I have a vague memory of seeing something about "Download the latest Catalyst drivers" somewhere. Other than that, I give up. Sorry.

Did you install the Stream SDK 2.2?


Yes - followed the install to the letter - see posts 26284 & 26357 earlier in this thread. I guess I have to chase my tail with many attempts to get the right combo or sequence, but that's scary with the recent fglrx issues. Why can't they just ship the SDK runtime with the cat drivers like normal folks do?

Which Catalyst driver version do you use? 10.8 or newer?

Whatever ubuntu 10.04 + patches is.
I always found that chasing the ATI drivers eventually got me an unbootable system.
And when CVE-2010-3081 got fixed, I got one of those anyway.
This is the downside of ATI...

I can't find a minimum cat driver version in this thread, and the SDK didn't specify either that I can remember - so, what is the actual minimum?

For the Stream SDK 2.2 / Open CL 1.1 it's the latest 10.9 driver according to the SDK download page:

ATI Radeon™ HD - ATI Catalyst™ 10.9 Driver Suite

You can get them from the x-updates ppa:

10.7 is the absolute minimum, though it is only partially supported (and did not work perfectly for me on the tests earlier). 10.8 is probably the true minimum for the SDK that was previously used in testing earlier in the thread, but ATI changes these relatively rapidly so you should update to the latest for best results.

Message 26920 - Posted: 8 Oct 2010 | 17:21:24 UTC

I'm getting reports from a PSA tester of errors with the following range on Windows:

    -p6900015e6 -P6900016e6 -k 1201 -K 9999 -N 2000000 -c 60 -R

It should report the following factors, and does on my Linux64 CPU emulation:

6900015037673 | 7137*2^1445798-1
6900015118459 | 1577*2^1108206-1
6900015199963 | 8839*2^81555-1
6900015510929 | 6177*2^1704558-1

But I get errors on Win32 CPU emulation, which are different from the errors reported by the other user.

Can someone with Windows who's run the standard tests run this one to compare? How about someone with Linux 32-bit? That would clear up a few things.

Thanks!

It worked for the guy with the original error as well! I'm now checking to see if his original command line produces the error.

But that was a good range to test anyway.

It certainly appears safe to run on BOINC. The Computation Errors only seem to appear when running with a sieve file. It's very possible that my Git merge created a bug in the sieve file reading code.

If you got a Computation Error in BOINC, your WU would error out. If you're not seeing that, there shouldn't be any problem.

Alright, PPSieve-CL v0.2.1-beta is ready for testing. It should be faster than the last version; but I'm really unsure by how much. OpenCL seems to be a relatively slow language.

Also, the sieve file computation errors bug is still a mystery. It's not something I changed in reading the sieve file. So long as it finds the right factors without a sieve file, it should be OK to use this in BOINC.

Still list the 4670 incorrectly with 640 SPUs (should be 320)?

Do you need it tested on the other ranges in the thread?

Looks like this one's going to need some work. :(

If someone's looking for a good version to use with BOINC, use this instead.

That link might not have been accessible for anyone but me. I've now reverted to v0.2.0-beta, and I'm sticking with that.

Upon further reflection, it may not be possible to implement the latest algorithm on OpenCL. It appears that converting from vector long to vector int actually takes some operations in OpenCL; the algorithm depends on casting long to int with no cost.

So I'm sticking with v0.2.0 beta and never buying an AMD GPU. Hey, at least I finally made a decision! :P

OpenCL certainly seems limited compared to native algorithms as with CUDA on the NVidia cards. Have you thought much about trying to do the app in ATI's native Brook/CAL? The Collatz project was able to do their app that way, but I have no idea how difficult it is to work with the ATI cards this way...

Yes.

Well, I couldn't do it without buying an ATI card, and I don't want to buy an ATI card if it's going to be slower than an nVIDIA card. Catch-22!

Also, the current fastest algorithm on nVIDIA is very linear. ATI needs instruction-level parallelism, and evidently that's not easy to come by. So I'm not sure CAL could do much either. Certainly not sure enough to buy an ATI card.

On the other hand, the vectorizing I did on ATI only gave about a 33% speedup. It might be worth un-vectorizing it and applying the newest algorithm. But ATI/OpenCL is so unpredictable that I'm not inclined to try this soon.

Rumor has it i do get back my vendor-"repaired" ATI 5770 in the course of this week.
I would take a look into it, but CAL seemed to me as a big pain in the back and there is (or was?) not that good documentation available as for CUDA.

Very interesting work Ken_g6!

I'll have to see if I can get the code to compile and run on my Macintosh. It seems to be going well so far, with only minor modifications, the compilation part at least.

Some progress (the executable name lies):

$ ./ppsieve-cl-x86_64-linux -p42070e9 -P42070010e6 -k 1201 -K 9999 -N 2000000 -c 60

Thread 0 starting
Detected 160 multiprocessors (800 SPUs) on device 0.

I still need to compile the boinc libraries to get the -boinc version... but even this failure is promising at this point.

I couldn't do it without buying an ATI card, and I don't want to buy an ATI card if it's going to be slower than an nVIDIA card. Catch-22!

I don't want to be unrespectful, but I think that with a decent algorithm, in these calculations ati cards should be really faster than a similar nvidia.
Anyway, thanks for your work. It's also open source, so when somebody will be able to go onward (time is not free, unfortunately), it will start from there.

FWIW... the real 'problem' here is openCL and it's JIT... It's crap.

Just a tip... http://sourceforge.net/projects/calpp/ that should make it easier...

Maybe i ask that to early, because you still try to test the application and BOINC will come later. In these case, i will ask later again. ;)

After pschoefer told me that there is an way to crunch for PG on an ATI i tested it under BOINC. And cool - it works fine (as long as i deactivate manually my onboard ATI HD 2400 on Device0).

Prior that, i tested the sieve on cmd.exe, it find the correct ATI-card and ignored the HD 2400.
Under Boinc instead it starts one wu with device 0 and compute correctly (remember, according to BOINC, the device 0 should be the HD2400 ?!?), then it starts a second wu with device 1 (at normal the ATI 5750 ?!?) and immediately produce an error.

As result (ignoring the wrong device-output):
The ATI HD 5750 (725/1150MHz; Device 1) crunch and crunch and crunch.... ;)
The ATI HD 2400 (when active) produce error on error on error... :/

My question: Is there a way to exclude the HD2400 for PG? The card could crunch for Collatz (RV610-Chip... not fast, but the card works). Is there a way to write it in the app_info.xml or is that a problem, i can't solve?

Thank you for your regard.

I doubt that you crunch with the CUDA version on an ATI card :)

I think you tried to get the OpenCL version to work on your 5750 and since
OpenCL (to my knowledge) doesn't support your HD 2400 it selects the right
card running the application through the command line by simply ignoring the
not OpenCL capable HD 2400.*

If you use app_info.xml files for Collatz and PG you could try to add a --device X
switch to the command lines with X denoting the device you want to use for the
respective BOINC project (HD 2400 for Collatz and the 5750 for PG) but I don't
know what BOINC will do if it has only work for the PG project and tries to start two
work units which will then end up on the same card (via the added --device X) switch.

*Even if BOINC sees your HD 2400 as device 0, for the ATI OpenCL app
device 0 is most probably the first OpenCL capable device and that is
your 5750.

CUDA.. was wrong.. jepp :D My mistake... and cancelled in text. And yes.. i meant the openCL. ;)

Okay, that explain, why in BOINC it crunch on device 0 (instead the BOINC tells me, that device 0 should be the HD 2400). Thanks for your explanation.

I will try to test it via the app_info.xml.... and pschoefer has to explain it. He has more knowledge with that. :D

Thanks for that hint. :)

there is an option for the cc_config.xml file which is <ignore_ati_dev>N</ignore_ati_dev>, but i don't know if it will work in an app_info.

Thanks tepek for answering,

It seems, that the <ignore_ati_dev>N</ignore_ati_dev> -option only works on the global settings-file from boinc.

Spamguy, as you can read on http://developer.amd.com/gpu/atistreamsdk/pages/default.aspx your card is not listed and so, the card won't work. ;)

But if you want the card to do something; Especially Collatz@home (don't know a second project ad hoc) also works with Radeon HD 2400.

D'oh, you're right. I didn't expect the 2400 to be omitted from any compatibility lists; it's not that old (~3 years) or rare.

Collatz? Meh. Primes (or lack thereof, if we're dealing with sieves) are cooler. :)

Now to debug the source of the Program build failure. Up to this point there haven't been any code changes, just some redefining of files in headers and editing the Makefile.

I seemed to have missed the "c " in "-c 60" in the above example, but the error remains. Tackling that error is the next project.

Oh, yeah, this was the error:

-c does nothing on BOINC. Try this for starters:

So.... As long, as the Problem with two GPU (but only one serves correct conclusions) exists on BOINC (and there's no other way to disable one GPU for a specified project), i disable the wrong one. :/

Better for all projects would be a '<ignore_GPU_dev>N</ignore_GPU_dev>-option' for the project-app_info.xml (as I said). ;)

On Radeon 5870 ( 900 MHz core, catalyst 10.10 ) took about 215 s on 1 wu in PPS sieve. Is it good, or not? :)

Is there a chance, that this application speed up like the cuda app?
I don't think that is everything what 5870 can do.
