Message 19019 - Posted: 8 Nov 2009 | 23:03:01 UTC

Hello

I am working on a AP26-version for CUDA.
I do need contact with some persons with CUDA-capable devices.
Personally i do own a GTX260, i search persons with following devices:

GeForce GTX280/285 or Quadro FX 5800
GeForce GTX295 or Quadro Plex 2200 D2
Tesla C1060
Tesla S1070

And Linux x86_64 as OS to verify my app is working and get some base for comparison.

please PM me.

Am I correct in assuming that your lack of request/need of series 8 and series 9 CUDA devices is due to the need to enable double precision calculations via 1.3 compute capable cards?

No. I do not use double floating-point calculations.
I am in need of device-capabilities =>1.2 since for now i do use way to much registers for the kernel.
With 64 registers/kernel a GTS 240 would have to launch 88 blocks with 128 threads/block. Having only 16 Multiprocessor for executing those blocks performance would not be the best. A cuda 1.2-capable device (or higher) - e.g. a GTX 260 - could launch 44 blocks with 256 threads/block since a block could use twice as much registers as on cuda 1.1-capable devices. I am currently figuring out how to carve out additional registers out of the code to further boost the application but i need more test rigs to evaluate the current app.
As it stands for now only GT2xx-cards are usable.

One question i do have: Is a GTX 295 or 9800 GX2 recognized as two devices or as one?

Okay the beta-app yields following results for KMIN=366384; KMAX=366384 SHIFT=0:

GTX 260: 27 MP; 1242 MHz; 251 s
GTX 285: 30 MP; 1476 MHz; 201 s

Overhead is for memcpy to and from host/device.

I'll be the first to say it, congrats on getting it to run on a gpu!

it seems as though it needs some work to be faster (much like my initial ps3 app).

I've thought about doing a gpu port, but with limited time, this has not happened yet.

I have access to older Nvidia Cuda cards, and double precision 48xx series ATI cards.

What are your thoughts on sharing your work thus far? I seem to be pretty good at optimizing code rather than writing from scratch with limited time.

thanks,
bryan

9400 GT: 2 MP; 1400 MHz; 3094 s

how lame...



Well, I think I'd disagree with how lame that really is.

3100 sec per AP26 unit is faster than the per core time (32-bit OS) on Prescott P4, Pent D 820, Core Duo T2450, etc. In fact, it is only about 10 minutes slower than one core/thread of a Prescott P4 HT @ 3.6Ghz (about 2500-2600 sec) on 64-bit OS. At about $35 for an entry level, 16-shader CUDA device, I think the 9400GT isn't doing too badly (3100sec per workunit running 24/7 with 23.61 credit/unit = about 650 credits per day). Indeed, with those times, a 32-bit card (e.g., 8600GT, 8600GTS, 9500GT) could about match a 64-bit P4, and the 64-shader to 128-shader series 8 & 9 cards (at about $45 - $120) would probably match or modestly outperform many of the Core2 cpu's even when running 64-bit.

Compared to Collatz (where I have 16-shader CUDA and equivalent 40-sp ATI devices), the 9400GT here appears to get about 1/2 to 1/3 the credit. While this is obviously significantly less, it is not too bad for a first go at the app.


Oh, and a very big THANKS for working on this!

Okay, i put it up AP26-plainc-0.03a.
All cuda-devices with compute-capability =>1.1 are allowed for now.

Not supported:

GeForce 8800 Ultra, 8800 GTX
GeForce 8800 GTS
Tesla S870/D870/C870
Quadro Plex 2100 S4
Quadro Plex 1000 IV
Quadro FX5600
Quadro FX4600

will work on reducing polling for kernel-completion and on integrating into AP26-boinc-code now before looking for other speedboosts. I think getting this to work in boinc should be the next step and afterwards one could try to gain more speed.

hm seems like the version 0.03a compiled for 1.1 is significantly slower on the GTX 260 than version 0.02a, can anyone confirm this?

EDIT: Never mind - it is as fast, i should not have passed a vga-kernel-option, this was terminating the other version too.
It would be nice if some of you would give it a try on your hosts and report back:

Type of graphics card, MPs, Speed of card in MHz, runtime of the app in seconds.

I have the deviceQuery of the cudaSDK here to obtain these information. I think this program is public domain and could be shared, if not i would remove it, but the source is openly available via nvida, so i think it is.

I updated the app AP-plainc-0.03a, it now reports the available devices with stats:

# ./AP26-plainc 366384 366384 0
2 CUDA device(s) found
[0] GeForce GTX 260 (27 MPs; 1242 MHz) cuda-cap: 1.3
[1] Quadro FX 580 (4 MPs; 1100 MHz) cuda-cap: 1.1
which device to use?:

Please only input integers or you have to [CTRL]-[C] ;)

@Scott Brown: I would not be 650 credits/day as the 23.61 credits are awarded for 6 K in a WU and i only computed 1. So it would me more in the region of 110 credits/day.

That's why they invented the saying: beg, borrow or steal. I'm sure there are a lot of participants that will help out in this endeavor if it means getting a GPU app.

Ask and you shall receive.

30 Days to 16 December

Let's see what we can accomplish in 30 days!!! While the Winter Solstice Challenge doesn't begin until 18 Dec, I figured a 2 day buffer would be nice. Currently we have the following:

- Feasibility of AP26 running on a GPU is successful!!! Congratulations to roadrunner_gs!!!

16 November
- AP26-plainc-0.03a
- Linux x86_64 only
- compute-mode only
- cuda->=1.1-capable devices (G2xx-model)
- single test times

GTX 285: 30 MP; 1476 MHz; 191.00 s (1146 s for a 6 K WU)
Quadro FX 580: 4 MP; 1100 MHz; 1917 s (11502 s for a 6 K WU)
9400 GT: 2 MP; 1400 MHz; 3094 s (18564 s for a 6 K WU)

16 December GOAL
- Linux 32 & 64 AND Windows 32 & 64
- compute-mode and BOINC compiled
- single test times

???
The elite 64 bit machines are coming in at 430 s to 700 s for a 6 K WU.
The bulk of the fast 64 bit machines start entering at 790 s to 800 s for a 6 K WU.
PS3's are around 660 s for a 6 K WU.

- cuda->=1.1-capable devices (G2xx-model)



Just an FYI...

CUDA devices with 1.1 capability actually include all 9xxx series cards as well as most 8xxx series (excludes the cards based on the G80 chip which are 1.0 compute capable). Several Quadro and Tesla cards/devices also have compute capability of 1.1 or later.


@roadrunner_gs
The only difference between 1.0 and 1.1 compute capability is the addition of atomic functions. If you are not using these, then the 1.0 cards should also work.

Yes i know, will change the code when at home to enable 1.0-devices.
I could compile Windows x86_64 apps in a vm with a Win7RC or Win2k8RC but i have no systems at home with CUDA-capable graphics card and x86_64-Windows.

I am gone to a conference for the week starting tomorrow, but I have a couple of 64-bit Windows boxes with 1.1 compute CUDA devices installed that I can test on when I get back (also have some 32-bit systems available to test as well when/if we get to that).

I could compile Windows x86_64 apps in a vm with a Win7RC or Win2k8RC but i have no systems at home with CUDA-capable graphics card and x86_64-Windows.

Some of the users & developers who have collaborated to produce the current applications (Linux 32 & 64; Windows 32 & 64; PS3/Cell Blade) for AP26:

geoff, Menipe, Honza, Jarek, sesef, BerndBrot, Augustine, rogue, mfl0p

It was very exciting to watch how quick the apps were improved when the collaboration began. Anyone who wishes to follow their dialog and improvements can view them here: Improving the AP26 application

If I remember correctly, sesef, rogue, and mfl0p all are capabile of compiling in Windows. With mfl0p's recent (10 Oct 2009) optimizations to the AP26 application for Intel 32bit & 64bit Windows, I recommend him as the first to contact.

So i got the app for boinc to compile but for now it is SIGSEGV-ing.
The app is able to query available devices but can't handle them.
Seems like something with the libcudart.so is fishy...

You could also ask the Collatz guys, they have that running on CUDA as well as ATI devices.

Have you read this on the collatz home page? You might have to wait a few days...

Vacation Time
November 12, 8:05 CST
For the next 10 days, there will be limited support and monitoring of the Collatz project while I am on vacation. I'll try and check it once or twice a day if Internet access is available.

I know, was kind of a surprise to me too. I guess something went on in the past but I did not want to dig into it..

It is strange that the app is able to query the available devices but is not even able to copy the smallest array onto the device. I think i strip down the entire AP26 down to a skeleton and do nothing than call a kernel. Let us see what the outcome is.

Okay, the app is working now with boinc-extras on the command-line.
I forgot to initialize one counting-variable.
Alas it is failing in boinc though.

Would anyone know why I can run CUDA apps like GPUGrid in BOINC, but the code for the AP26 does not recognize my card?

I have a GeForce GTX275, running on Ubuntu x64

On the commandline file SOL-AP26.txt matches that of the project-app.

please verify it working comparing SOL-AP26.txt with several WUs crunched by this app and the standard-app.

A-OK, it seems to work now.
But he can't compute multiple K yet...

look here

stderr.out

<core_client_version>6.4.5</core_client_version> <![CDATA[ <message> process exited with code 1 (0x1, -255) </message> <stderr_txt> Cuda error: memcpy: setting the device when a process is active is not allowed </stderr_txt> ]]>


May i request some AP26 with only one K or is this to much out of?
Will look into this.

what have i done?
1. altered the app_info.xml to the one that is downloadable from my server
2. copied my app to /usr/sbin since i found somewhere this should help (without this the app is failing, no idea why...)

EDIT: Okay, fixed this with calling cudaThreadExit when completing SearchAP26.

Are you really using BOINC 6.4.5 ?

Might be worth trying a later release like 6.10.18 or so.

I had problems with the Collatz linux CUDA app under 6.6.36 which mysteriously went away when jumping to 6.10.x

The graphics-card did it: link
Compared the SOL-AP26.txt to one calced in parallel on the CPU in standalone mode and they matched...
I have uploaded the app here AP26-boinc-cuda-0.01.
You could try also, but follow the two steps i posted, okay, i do additionally have the cudart.so in the project-folder of www.primegrid.com and in the BOINC-root-folder.

The graphics-card did it: link
Compared the SOL-AP26.txt to one calced in parallel on the CPU in standalone mode and they matched...
I have uploaded the app here AP26-boinc-cuda-0.01.
You could try also, but follow the two steps i posted, okay, i do additionally have the cudart.so in the project-folder of www.primegrid.com and in the BOINC-root-folder.


Trying it, all set up and attached but I have to run out and pick my kids up from school - will check when I return.. pity there is no GPU only flag for Primegrid yet..

Excellent work btw!

Bok

p.s. had to rename the CUDA app to match the app_info.

Yes, forgot to do so and fixed it yet.
Am going to bed now, have to catch up some sleep lost in the past few days. It is quarte to midnight over here.
Please adjust your cc_config to just use one cpu, i do not know what would haben if multiple of this app are running in parallel...

good night for now.

I trashed one WU right now (Cuda error: kernel invocation: the launch timed out and was terminated) while checking the CPU/GPU-temperatures: CPU=40°C; GPU=72°C - i had to switch to a x-window for that.
Suspended work and GPU-temperature dropped to 50°C and the CPU-temp to 36°C.
But that means there is still room for improvement in the app.
A mode where all Cores and the GPU are used would be cool.

I did some minor changes, AP26-boinc-cuda-0.02 and updated the app_info.xml to reflect this. I will finalize the downloaded WUs and start over under Windows x86_64. Can't test there, though. Will buy a Windows 7 Pro x86_64 at the end of the month.

Does it really need to have avg_ncpus/max_ncpus = 1.000 ?

Other cuda apps have this set to 0.04..

And I see it using a full cpu too..

Yeah, from what I understand, in GPU applications, the CPU only needs to be employed minimally. The CPU can spend its time working on its own WUs.

That is a very good question what to put in ncpus - i have not the least idea.
And no, the app is not using one cpu, it is idling waiting for the kernel to complete. If you let other tasks run it should gracefully step a little bit in the back row, i saw it only using half a cpu on my client in standalone-mode.

I fixed a severe bug where i assumed there only would be one AP>10 per 10840-passes.
The new code would allow for 10840 APs > 10 per tested k, that should be sufficent but could be increased if necessary. Due to this change and the use of atomic-transactions i had to drop 1.1-support (older Tesla 870 and G8x). Thanks to mfl0p who also spotted and reported this bug to me.
The new version is AP26-boinc-cuda-0.03, the app_info.xml is updated to reflect the new app-name.
Since the main kernel needs that long the only way to support this app under Windows is when running the graphics-card in compute-mode. I would change the code to use the second graphics-card - if available - and switch that one to "compute mode"

I think you mean dropping support for compute capability 1.0 (the G80 NVidia chips) since version 1.1 is where atomic functions was introduced?

Currently for cc<=1.1 those theoretical MIPS-values must be multiplicated by 0,17 and for cc=>1.2 multiplicated by 0.25 to get the MIPS with my app (that is the occupancy of the MPs).
A Core 2 Duo T8300 with 2400 MHz has 4800 per core, a Xeon 3520 with 2666 MHz has 5319 per core (without hyperthreading i think...) read from /proc/cpuinfo, that should be theoretical performance too.

I experienced some strange issues while rewriting a little bit of the code.
x-Window is now running, i have the app AP26-boinc-cuda-0.04 on my webserver as usually and updated the app_info.xml. Some advice while creating a good app_info.xml would be cool too.
Please try to test and report back. Next focus is Windows, maybe mfl0p could focus on Windows?

I took some loops out of the kernel and am now invoking the main kernel several times.
Now the main kernel takes less than 10 seconds ahd it could be run while displaying the desktop since the kernel-runtime is less than the kernel-start-timeout. The kernel now also uses less registers, but increasing the MP-occupancy does not help for now, i think i have to copy some of the global-arrays to local-ones to speed RAM-access a little bit.

when i remove "<coproc>

The app will actually run on my system now, however using the computer is impossible while the program is running due to slow screen updates. Also, the solution file is not in the same order as the official apps, so if there was a double check, it would be marked invalid, correct?

I do not know if the order is important for double-checking.
The get reported in the order they appear, if the output of both the stock-app and my app is sorted both are matching.
I updated the app + app_info.xml now and get

Will test a bit and also with the stock app running in parallel and release later this day i think.
And yes, the desktop is very slow, but this is what i experienced under aqua too.
The app was failing because i did not parsed the --device {deviceId} which would be handed in by boinc so the app is - or was - failing.

whoa!

Okay.
I updated the app, no CPU-load anymore - at least on my system.
Window-manger is a bit slow still but usable if one is patient...
Progress in BOINC is therefore not monitored in my BOINC-manager...

I have put the entire program on my webserver:

AP26-boinc-cuda-0.05 the app, to be put in ${BOINC-folder}/projects/www.primegrid.com/ (and possibly /usr/local/sbin/ or /usr/sbin/ or the like)
app_info.xml to be put in ${BOINC-folder}/projects/www.primegrid.com/
number_of_gpus specifying the number of gpus in the system, to be put in ${BOINC-folder}/projects/www.primegrid.com/
libcudart.so.2 as shared-library, to be put in ${BOINC-folder}/projects/www.primegrid.com/
cc_config.xml to specify how much GPUs in the system to use and to check WU-distribution, to be put in ${BOINC-folder}

with all these i am running 8 CPU-WUs and 2 GPU-WUs on my client

I would prefer not to know how much Watt this system is drawing out of the wall plug right now... ;)

Please test and report back...

If no more problems arise i think this could be made public...
Switching over to windows on Tuesday or as soon as my employer has transfered my wage for November.

Okay.
I updated the app, no CPU-load anymore - at least on my system.
Window-manger is a bit slow still but usable if one is patient...
Progress in BOINC is therefore not monitored in my BOINC-manager...

Testing with this host.
Seems to run fine. Window-manager is slow but usable.

Intel I7 920@2,67GHz + GeForce GTX285
Running 8 CPU wu's (~24min/wu) and 1 GPU wu (~21min/wu).

This PC is taking 350 Watts out of the wall plug, but the energy is needed for heating the premises anyway.
