Message 53564 - Posted: 30 Apr 2012 | 13:02:33 UTC

I have been working on an OpenCL version of wwww for a few months (on and off). It's been slow due to a change in architecture and a lack of free time to work on it.

The original version started with the architecture of wwww. I quickly realized that the sieving code in wwww couldn't feed the GPU fast enough to keep it busy. I then turned to ppsieve. Although ppsieve has a faster sieve, I found that it had the same problem. I then found primesieve (at code.google.com). It is the fastest implementation of a sieve I found.

The end product is a framework called GPUSieve. It is a framework for problems of this nature. By 'problem' I mean a program that sieve for primes, then for each prime, do something with it on the GPU. It is written in C++ and is multi-threaded, something which the other programs cannot do.

The new code is screaming fast compared to the current CPU only code. I estimate that my ATI Radeon 5770 could complete a Wieferich range for 3.5e16 in a year, that is more than twice the total amount of work done on the search since it started in the 80's. The WallSunSun code should be able to do at least 4e15 in a year, but I haven't done enough time testing of that code.

I hope to release the source code tomorrow along with Windows and Mac builds. I only have the ATI Radeon 5770 to test on (and a really old ATI Radeon Mobility), thus I am looking for some people to help beta test on their hardware. Once I post the code, I will provide details on how I want you to test it.

I can test with several different NVidia GPUs. These projects require a 64-bit OS for the current PRPnet CPU app. For the OpenCL app, is this still true, or will 32-bit be possible?

A 32-bit build is possible as there are no dependencies on 64-bit asm instructrions. I haven't built/run a 32-bit version though.

No. There are no floating point operations in the code as the FPU would overflow with the numbers being tested.

Message 53599 - Posted: 1 May 2012 | 2:07:57 UTC

I have posted the code (along with a Mac build) here: http://home.roadrunner.com/~mrodenkirch/wwwwcl.zip.

My estimate for 3.5e16 in a year was on a ATI Radeon HD 5870. I have a Windows box with an ATI Radeon 6450, but the program hangs on that. I suspect it is due to mixing a 32-bit exe with the 64-bit OpenCL library. I'll try to fix that in the coming days.

Since I can't provide a Windows build yet, there is a VS2008 solution included. If you have VS2008 (or newer) and want to build it, you just need to install the AMD APP OpenCL development toolkit.

I don't have access to any Linux systems, so I cannot build the code for Linux. I have also been lazy in that I didn't write a makefile. I built on the Mac with this command line:

gcc *.c *.cpp opencl/*.cpp wwww/*.cpp sieve/*.cpp -m64 -framework OpenCL -lstdc++ -O2 -o wwwwcl

I assume that on Linux you just need to replace the "-framework OpenCL" with the appropriate -I and -l options to include the OpenCL headers and libraries on your system.

Execution is fairly simple:

./wwwwcl -p1334568e11 -P1334569e11 -TWieferich -t5 -b2000

where -t tells the program how many threads to execute and -b is the number of blocks per thread. Here is what to expect for output:

wwwwcl v2.0
Compiled Apr 29 2012 with GCC 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.1.00)
Sieve started: 133456800000000000 <= p < 133456900000000000
p=133456892569421833, 9.560M p/sec, 1.07 CPU cores, 92.6% done. ETA 29 Apr 18:52
Sieve complete: 133456800000000001 <= p < 133456900000000000 2535955284 primes tested
Elapsed time: 265.35 sec. (1.85 init + 263.37 sieve) at 9557118 p/sec.
Processor time: 282.66 sec. (1.86 init + 280.80 sieve).
Seconds spent in CPU and GPU: 1066.99 (cpu), 124.43 (gpu)
Percent of time spent in CPU vs. GPU: 0.90 (cpu), 0.10 (gpu)
CPU/GPU utilization: 0.20 (cores), 0.02 (devices)

You will see more detail with the -v switch. I recommend starting with a smaller number of threads and blocks as you will use those to find the optimal settings for you GPU.

As part of the testing you should run ranges that have known Wieferich/WallSunSun special instances and ranges without them and thus verify the output.

I think it very likely that this program will either not run or will crash for some of you and might hang the system of a few others. (I experienced a few hangs during my initial development, so you aren't alone.) In all seriousness I strongly suggest starting with small ranges, 1e8 or so, and small numbers of threads and blocks until you get more comfortable running the program and feel that it will run safely on your hardware.

What I'm looking for is problems compiling and linking, problems at runtime, i.e. OpenCL errors output by the program, and any other serious issues.

This code will NOT work with PRPNet, at least not yet. I have to make some changes to both the client and server to support this program and I really don't want to support it until the major kinks are worked out.

Thanks.

You should also be able to run the code on an NVIVDIA card, although I don't know if you need the NVIDIA OpenCL toolkit for that.

If you use the -l option, wwwwcl will list the available platforms and devices on your system. The default is to use platform 0, device 0. You can override with the -p and -d options. You will need this if you have multiple GPUs on your system.

I ask you to test other ranges, not just the example I gave. I suggest that you look at special instances on the PRPNet server to get some ranges to test. You will need to use the -s option to change the threshold for special instances. It defaults to 100.

You should also vary the values for -t and -b so that you can determine the optimal settings for your GPU.

On some systems, the GPU is so fast that the GPU is starved for work. You can run multiple instances of wwwwcl concurrently to keep the GPU fed. To reach the 3.5e16 yearly throughput, I could run 3 instances of wwwwcl.

I can speed up the GPU code more, but it was more important for me to get this beta out first. I don't know when I'll get around to further speed-ups.

Do you have ZoneAlarm installed? I googled this message and the first hit implied that ZoneAlarm was the cause.

When I try to run the 64 bit Win build with

wwwwcl -p1334568e11 -P1334569e11 -TWieferich -t5 -b2000

I get an error message saying something like

The application could not be started (0xc000007b). Click "OK" to close the application.


Tried to run under Windows using a ATI Mobility Radeon HD 5470.


Do you have ZoneAlarm installed? I googled this message and the first hit implied that ZoneAlarm was the cause.

No I haven't. I also googled a bit and found this. I will check whether that does something.

Neither windows build will run for me. I get an immediate program "stopped working" message without any output or a log file. This happens when I run with just the -l option.

That isn't very helpful. If any of the OpenCL calls fail, then there should be a message echoed to the window before the program stops. I probably need to add more diagnostic messages when using the -v option.

Does anyone here have Visual Studio installed AND an NVIDIA GPU? It would be a great help to me if you can investigate this.

http://msoos.wordpress.com/2010/09/11/0xc000007b-error-solution/ says the error 0xc000007b is caused by a 32bit application that tries to load a 64bit dll.

Iam trying to compile the nvidia app but got an error. Need more time to investigate what cause this issue.

No errors after installing the libraries from MS.
CPU use was 33 % (of 4 cores) for -t values 2 and above.
GPU-Z showed 96 to 98 % GPU usage so this old card can be fed by just one instance of the program. With just one thread, GPU usage was between 60 and 70 %.
Tried different -b values from 500 to 5000 and the differences were minimal but 3000 appeared to be best.

Will post results on a GTX 560 Ti later.

The win64 bit app does not work at all on my win7 64bit with an nvidia card (gtx 570)... 32bit did work and this is what the log says:

So it works it seems. Top marks! Though I am slightly worried about the cpu usage. It almost used two full cores. Is that worth switching over to GPU for?

Edit: System: Win 7 64bit, i5 2500k, gtx 570, nothing else eating away at the cpu.

@all: The win app is only for ATI cards, you will get an error with a missing ati driver file and the app is crashing on nvidia cards.

Through reading here, some got it running on nvidia cards. I dont know how and why???

So it works it seems. Top marks! Though I am slightly worried about the cpu usage. It almost used two full cores. Is that worth switching over to GPU for?

Edit: System: Win 7 64bit, i5 2500k, gtx 570, nothing else eating away at the cpu.


Note that the Wieferich GPU code on your box is probably 10x (or more) than the CPU version of the same code, so even if it takes more than 1 CPU, it still is better to use a little extra CPU to feed the GPU.

Try running with -TWallSunSun. That code relies more heavily on the GPU than the Wieferich code.

I needed only to make sure the libraries in the system matched the app (32 vs 64-bit).

Well, I installed the package from MS and it worked immediately. Links: x64 and x86

You may need to copy the files msvcp100.dll and msvcr100.dll from 'Windows\system32' to the folder of the executable. That Dependency Walker utility (available via the link Toshio posted) could be useful.

Please do not post exes without code. I maintain the code base and the official builds (with help from rebirther). If you don't mind, could you send me the code change you made. I prefer e-mail rather than the forum or PM. My e-mail is rogue @ wi.rr.com.

I think I know what you changed. I had removed ParallelPrimeSieve from the sieve folder since I wasn't using it. I can re-add it then have App.cpp instantiate it instead of PrimeSieve. Nevertheless you can send me your code changes just in case you did something differently. The biggest PITB might be dependencies within ParallelPrimeSieve for other libraries.

If your elapsed time is much greater than processor time, then you should reduce the number of threads.



This might not hold true for the Fermi NVidia cards. Using -t4 or -t2 slows things down slightly on my GT440 OEM card compared to -t5. Increasing to -t8 (and using -b3000), however, almost doubles performance (and -t16 crashes the system).

I suspect that -t16 might be running out of GPU memory although there is code to check for that condition.

BTW, I'm sorry if I came across a little harsh. It is very important to me (as an open source software developer) that all source code on projects I support is readily available. It is also important to me that I sanction builds because I have little control over the development environment that everyone is using. It isn't that big a deal for wwwwcl, but it is for programs like pfgw. pfgw can be messed up easily if someone is not careful as it has so many dependencies on third party libraries. When that happens I'm put on the hook for someone else's code (and mistakes) when I have no idea what they changed.

If you too many threads I think that some of the additional GPU time is spent waiting to execute in the GPU. It would be interesting if you vary -t and -b more. For example, try -t3 -b10000.

The error with clGetKernelWorkGroupInfo is due to the requirement for OpenCL 1.1. The code in wwwwcl is not supported by OpenCL 1.0. Can anyone tell me the minimum driver needed to support OpenCL 1.1? I'll add that information to the readme.

For NVidia, it looks like you need something above the 280.13 (Linux) or 280.19(Windows) drivers.

It would be interesting if you vary -t and -b more.

@rogue: Is it possible to add a function which do some short tests with settings for -t and -b and give an output to determine the optimal setting/throughput?

64-bit version creates empty wwww.log
32-bit version does nothing at all (no output, no errors).

Updating driver to 301.32 and 64-bit version is doing fine.

EDIT: Sesef's version doesn't work, perhaps 64-bit version would.


I got the same error with toolkit 3.2 and 4.2 (compiled app). Driver version 285.62. Iam not sure why. The app should run with 3.2 but 4.2 need a new driver.

@Honza: Do you create the app and run or do you only installed toolkit?

Probably. Let me think about it. I hope to release an updated build with sesef's changes later today.

BTW, since writing such a function will take time and is not high priority, I recommend that someone write a script to run wwwwcl on a range of 1e10 (which will take less time) and vary -t and -b. Users could then use the script to run wwwwcl to see which values work best for their hardware. I think that running wwwwcl on 20 to 50 distinct -t/-b values would be more than enough for a user to determine which settings are best for them and should run in less than an hour for most users.

SR5 running on all four cores while testing. Also note that, while a bit slower, changes in -t from 2 to 8 have only minor effect.

I got the same error with toolkit 3.2 and 4.2 (compiled app). Driver version 285.62. Iam not sure why. The app should run with 3.2 but 4.2 need a new driver.

@Honza: Do you create the app and run or do you only installed toolkit?

Just took your app and updating driver to 301.32 and 64-bit version is doing fine.
Newer drives has OpenCL support, 260.x version was too old and no OpenCL there.

I got the same error with toolkit 3.2 and 4.2 (compiled app). Driver version 285.62. Iam not sure why. The app should run with 3.2 but 4.2 need a new driver.

@Honza: Do you create the app and run or do you only installed toolkit?

Just took your app and updating driver to 301.32 and 64-bit version is doing fine.
Newer drives has OpenCL support, 260.x version was too old and no OpenCL there.


Do you have a GTX6xx? The v301.32 is only for 6xx serie.

@all: Pls test these versions (prefered NVIDIA cards) with driver versions 296.xx and 301.xx. The program is created with cudatoolkit 3.2/4.1/4.2

Download

I must know if the program is starting or give an error.

This is most likely due to the driver not supporting OpenCL 1.1. I could change the code to remove this dependency, but it could hurt performance.

Previous Rebirther's x64 version was running fine on 301.32 driver.
Latest one x64 gives errors as Chru-chi, 32-bit has no output.

I've updated the source (and Mac build) to include the changes provided by sesef. No other changes were made. I'll let rebirther build the Win32 and Win64 exes as I still can get them to build and run correctly.

Make sure that you test ranges with known special instances.

Also, please test some WallSunSun ranges (-TWallSunSun). They are a little slower, but the software can verify that the code on the GPU was executed correctly whereas it can't do that for Wieferich.

I hope to test the PRPNet changes this weekend so that we can start using wwwwcl in production next week.

Updated versions with latest code:

32bit
64bit

There are some issues with 64bit and sometimes blackscreen. Pls report anomalies.

@rogue: I have no luck with cudatoolkit, all drivers supporting OpenCL1.1 but getting always the same error.

wwwwcl64.exe -p1334568e11 -P1334569e11 -TWieferich -t4 -b2000

Give around 14,25Mp/sec with GPU usage ~70%.
32-bit version does 10,6Mp/sec with GPU usage ~50%.
I wasn't able to get more GPU usage using differrent -t and -b switches. According to task manager, process still uses only around 1 CPU core.

-TWallSunSun crashes the app.

Interesting. The most likely possibility is that there isn't enough memory on the GPU to handle that many threads for that large a work group. WallSunSun does require GPU more memory than Wieferich, but not significantly so. A memory leak is possible, so I'll look into it.

WallSunSun will utilize the GPU much more than Wieferich, so I would not recommend using -t or -b values that are that large.

This doesn't explain Honza's issue though, although he seems to be having more issues than most other users.

Yes, I have seen around 3xxMB of GPU memory usage, but have around 600MB free.

I'm able to run 3 instances to get higher GPU usage on HD 7950.

GPU usage of my GTX460:
TWallSunSun=99%
TWieferich=~50%

But always too much cpu usage.

Do you have AMD SDK installed?

Yes, streamsdk_2-6-RC3_win764


This can cause a driver conflict. I have installed with a NVIDIA card, and the wwwwcl cause an error on start. After deinstallation its working.

Well, uninstalled all Catalyst stuff, restarted and...wwwwcl works as before. Means 32-bit version is still crashing and 64-bit version is still working and WallSunSun crashing.

Windows are still holding 12.2 drivers according to Device Manager.

Well, I was now able to really install and use 12.4 driver.
32-bit version is now working.

It leaves only WallSunSun tests crashing (both 32 and 64 versions).

Ok, better for debugging. It seems to be a driver issue. The card is very new. Can you check this with another HD6xxx or HD5xxx?

@rogue: I have no ATI card to debug the program, I hope you can find out what cause this problem.

@all: Anyone else have the same problem with a HD7xxx card?

I have an ATI card, but my Windows build freezes the computer. Could you e-mail me your zipped up solution folder (minus the .ncb and other temp files) and let me know which OpenCL SDK you are using?

Unfortunatelly not, at least not now.

I might be able to reach some low-end HD5xxx on Windows 7 x64 tommorow.
But this would need updating driver which I'm a bit hesitative...

I still can't get a build to run for me on Windows. It just hangs on a call to copy data from the GPU back to the CPU.

I did find a problem, but it is minor. I don't know if it is causing Honza's issue or not. I've sent the updated source to Rebirther for him to build.

Honza, can you install Visual Studio 2010 Express Edition? If so, could you assist in debugging the crash (assuming the patch doesn't work)?

Got VS2010Express1.iso downloaded.
What should I install and do? You can send instructions via PM or mail.

I found all MS Visual C++ redistributable 2005, 2008 and 2010 version , both x64 and x64 are already installed on my host.

Sorry about that. I've been lazy.

I don't think you have the right file. Go here: http://www.microsoft.com/visualstudio/en-us/products/2010-editions/visual-cpp-express and click on the download button. Make sure you choose VS2010, not VS2011 from the dialog it opens. It will download an exe. Double click the exe to install VS2010, which it will then download. Use the default install options. You will also need the AMD APP SDK.

A VS2008 solution is included in my zip file. You will have to upgrade it when you open it with VS2010, but that shouldn't be any issue. Use the "Build" option to build the solution. You can e-mail me with questions. Unless you are familiar with VS, you will need a little guidance with the debugging, but hopefully not too much.

I have sent him a link for the pro trial version. The Express version doesnt have 64bit.


I see. There should be little speed difference between 32-bit and 64-bit builds.

Build the Debug project (it is probably Release). It might squawk that it can't find inttypes.h. If so, you have to right click on the project and select "Properties". From C/C++ -> General is an option called "Additional Include Directories". It should have $(SolutionDir)\visualstudio in the list.

On the Properties dialog there is another selection called "Debugging". On that page is an option called "Command Arguments". Use that to specify the same arguments that you use on the command line.

Once built correctly, hit F5 to run. It will stop when it hits the bug causing the crash. I need the stack trace from that.

I'm sorry, but I haven't tested the next release of PRPNet yet. I have the changes and I had intended to test on Wednesday, but I didn't have my thumb drive with me.

I also have a few changes to wwwwcl, mainly a few stats and using of an ini file. No bug fixes. Honza's issue is still not resolved.

I've posted wwwwcl 2.1.0 at home.roadrunner.com/~mrodenkirch/wwwwcl_2.1.0.zip. The changes are:

Added more detail when using -v, such as the amount of GPU memory allocated
Added -q option to not print stats
Added wwww.ini file along with description of supported settings
Re-factored SharedMemoryItem

This will work with PRPNet 5.0.8, which I just released, but you won't be able to use it with either project until Lennart upgrades the server.

Windows users will need to a build from rebirther.

An OS X build is included. AFAIK, nobody with Linux has built and tested the code. I compile with the following:

gcc *.c *.cpp opencl/*.cpp wwww/*.cpp sieve/*.cpp -m64 -framework OpenCL -fopenmp -lstdc++ -O2 -o wwwwcl

on OS X. I expect a similar command for building on Linux.

Did you consider using a http://gitorious.org/, SVN or something else. I think it will be much better to share source than upload zip files.

At last, tried a linux build (ubuntu 11.04, gcc 4.5.2, nvidia driver 270.41.06). This was with your original release from several days ago. Finally got it to build after adding some #include and #define in main.h and App.h, and a couple of others... I can send along diff's after I pound on this some more. Still, with the following build command:

gcc *.c *.cpp opencl/*.cpp wwww/*.cpp sieve/*.cpp -O2 -I/usr/local/cuda/include -L/usr/lib/nvidia-current -lOpenCL -lpthread -lstdc++ -o wwwwcl -m64

the compilation still has lots of warnings like this:

App.cpp: In member function ‘void App::WriteCheckpoint()’:
App.cpp:516:50: warning: format ‘%llu’ expects type ‘long long unsigned int’, but argument 3 has type ‘uint64_t’

These were not present when I tried "-m32" instead of "-m64".

Still, I have a runnable, with all of the dynamic libraries resolved, so give it a whirl. Nope, no joy:

gary:~/Downloads/wwwwcl$ ./wwwwcl -p1334568e11 -P1334569e11 -TWieferich -t4 -b2000 wwwwcl v2.0 Compiled May 12 2012 with GCC 4.5.2 OpenCL Error: Invalid value in call to clGetKernelWorkGroupInfo kernelName: wieferich_kernel gary:~/Downloads/wwwwcl$

Not sure where to go from here, except to bed. Back at it later. I'll try your latest release (from a few hours ago).

I wouldn't worry about the compiler warnings right now, but please e-mail me your diffs.

Thanks. Is that OpenCL 1.0 or OpenCL 1.1? I will investigate a change to address that problem.

I'll try to fix the Windows project later today, but I have a really busy day, so I can't make any promises.

As for sesef's suggestion, I hadn't considered it. I won't make any decisions on it at this time.

Rogue,

Just shot you an email (your rr.com address posted earlier in this thread) with source diffs, compile command, compiler output, and a run attempt using your new 2.1.0 version. Same results as before.

Yes, it looks like an OpenCL 1.0 library. I'll scrounge up 1.1 somewhere, I'm sure, and give that a try.

32bit
64bit

Its possible that the app crashes with MSVCR100.dll. You need to install
Microsoft Visual C++ 2010 Service Pack 1 Redistributable Package

At this time my program crashed every time and I cannot find the problem. All packages are installed.

Tried it too, mine crashed as well until I tried without the -v switch, try giving it a go without -v.

For Rebirther's 64 bit (2.1.2 version) on trying to run it on a dual GPU I can't get it to recognise the second GPU properly, and I also can't get it to read the whole of the ini file correctly (except for the last 4 lines). I might be keying in the format of the values incorrectly into the ini file, anyone know the desired format?

It doesn't like the -v switch for me.

It crashed a few times when I had other cores busy doing other things, after a re-boot with nothing else running I've completed about 20 different tests without it crashing.

It does crash when I have additional cores busy.

Screen outputs available if required.

Does it crash immediately with -v or when the range is done?

For a dual GPU, use -l to list the platforms and devices, then use -p and -d to switch to the second GPU.

I can't speak for the ini file issue (yet). It's possible that I have a bug in the code. Make sure the lines don't have a '//' in the first two characters.

K Lewis is right, without the -v switch mine is running. The first time I got a bluescreen while I closed the window immediately.

The speed is around 5x higher than the old one but taking more cpu usage:

I'll try to investigate the -v option tonight to see why it is crashing. Most likely it is something stupid on my part, such as not passing enough parameters on a printf().


With OpenMP, wwwwcl will use a lot more CPU for the sieving. Wieferich will need more threads than WallSunSun to maximize GPU throughput.

Just out of curiosity, I gave 2.1.2 a try.
HD7950 crashing on Wieferich, possibly on msvcr100.dll with -v option.

Without -v option, 32-bit it goes fine. Using up to 3 cores, ~20M p/sec with nice GPU usage of ~95-98%.
>wwwwcl.exe -p1334568e11 -P1334569e11 -TWieferich -b2000 -t3
With -b2000, CPU usage goes down in final stages of computation (and so does Mp/sec)
But -b200 or -b500 crashes on first progress output.

EDIT:
64-bit version is similar in speed but lower CPU usage.
-b1000 looks optimal in terms of speed, CPU usage and screen responsiveness.

Sorry for the delay, I see the -v switch issue is being dealt with, it crashes just after prior to starting, after reporting running with x threads.

The mac version (2.1.0) worked fine with the -v switch.

I've got the dual GPU switches working now thanks, but it still crashes if too many cores are busy on other task for some reason.

I tested the new one on my GT440.

The throughput falled rapidly but gpu is used better than before...

Regards Odi


I suggest playing around with the -t and -b switches to find the optimal settings.

I found the problem with -v. It was due to a switch to use some macros which were used to address compiler warnings. I'll try to post it tonight.

Hi,

Long time reader, first time poster.. wanted to help test this new program out. Unfortunately not working for me.

Core i5 2500k @ 4.5ghz with 2x 4770HD in Crossfire. Using the latest 12.4 Catalyst drivers. This is the output from the 64bit version, I get exactly the same with the 32bit version.

MSVC redist installed.

This means nothing to me but I hope it's useful in helping test out !

That link appears to refer to the Fire Pro 7740 series. gribzy appears to have two crossfired HD4770 cards. I think those cards are supported.


The crossfire setup is probably the culprit (as has been SLI on NVidia setups for other GPU apps). I would suggest testing with crossfire disabled.

Can we have some output if GPU is not supported or driver is not supported?

Tested 2.1.3 with HD46xx and driver from 2011/05 and wasn't able to get any output at all (nor error). -?, -h, -v does nothing.

Same for GTX 580 with latest 300.xx drivers - no output at all nor error when trying to compute.

I don't know how to make such a check in code. There is plenty of error checking for all of the OpenCL calls, so if one of those calls fails you should get a message. I'm open to suggestions.

-l will list the valid platforms/devices.

Well, that's the point - it does nothing, no output to screen or log file at all.

I would expect something like "HDxxx not supported, get a proper card." or "Driver version not supported, get yourself updated to 12.2+"

I would expect something like "HDxxx not supported, get a proper card." or "Driver version not supported, get yourself updated to 12.2+"


That's very odd. When I run rebirther's 2.1.3 Windows build on a laptop that doesn't support OpenCL, I get this (when using -l):

List of available platforms and devices
Platform 0 is a Intel(R) Corporation Intel(R) OpenCL, version OpenCL 1.1
No devices
Platform 1 is a Advanced Micro Devices, Inc. AMD Accelerated Parallel Processing, version OpenCL 1.1 AMD-APP (851.4)
No devices
Fatal Error:
No devices were found that can run this code

If you use -l alone with no other parameters, do you still get nothing? I wonder if there is a missing dependency.

rebirther, can you rebuild with the following change:

In the Configuration Manager -> Configuration Properties -> C/C++ -> Code Generation -> Runtime Properties, set it to /MT instead of /MD. I don't know if this will change anything for Honza.

Yes, I get nothing at all whatever paramater of combinations of them are given. Both 32-bit and 64-bit versions, both HD46xx and GTX580. Will try HD7950 later...

Is there any way that you can debug this or somehow give me access to your machine to debug it?

Lower CPU usage (1+ cores), but screen is more laggy than with Wieferich. GPU usage aroung 95%-96% with Wieferich and 99% with WallSunSun.

Some heavy duty job (8-threads, larger block size). Version 2.1.3 looks more stable.

For WallSunSun you should choose either fewer threads or fewer blocks or fewer of both. You will still get high GPU utilization, but you will have less lag.
