Re: HCC1 Beta Test for Linux GPU (Issues Thread)

Don't know, since the HCC-GPU app is written for OpenCL, not CUDA. Think proper OpenCL detection did not start until v7, so in your case with a dual card config of NVidia it might be necessary to upgrade. Maybe other members have advise on how to config with v6.10 to stop HCC taking your GPU0

Personally, I'd switch the GT220(Make that GPU#0) and GT430 (make that GPU#1), as latter is the more capable crunching card, where the GT220 is a good display card. [per my previous post] My GT220 definitely fails on HCC-GPU [OpenCL 1.0, not the required 1.1], so maybe you may want to set the <use_all_gpus>0</use_all_gpus> which then automatically would select only your most powerful card... not enables your GT220 for BOINC, but then I don't know what else you crunch besides WCG or if gaming requires you to have the GT430 as GPU0. An upgrade to v7 may resolve this all.

Re: HCC1 Beta Test for Linux GPU (Issues Thread)

My results (with the GT430 GPU, gpu#0) are OK, no errors with HCC nvidia and pretty fast. I think the GT220 didn't try a HCC task yet, but there is no reason (except compute capability limit) that the GT220 would not achieve a HCC task.

I see that tasks sent to my BOINC client, have in their name 'hcc_nvidia_cuda708' (more or less). Then, I think that it's not OpenCL specific only, but nvidia.

I'll try to switch the card (by the .xml config file) to see if those tasks crash with the GT220 card.

Going with Windows is not an option for me, sorry.
And the GT220 have a bug, when using it on GPU#0 : the Nvidia Power Mizer option freeze the X server, and it's ok with the GT430. So the GT430 have to be in GPU #0 slot.

The two card crunches when I'm not using my computer, then almost all the time, no need to switch them :-).

I see with other tasks and let you know.
Thanks for answers.

Re: HCC1 Beta Test for Linux GPU (Issues Thread)

Longer ago I played with the Power Mizer and disabled it.

Don't know what Linux version you run [I've progressed to 12.10 Ubuntu], under which the GT220 does an excellent job for me. Check out the Synaptic repository on latest version, or one of the other maintainer ppa's such as LocutusofBorg. I'm running latters 7.0.39 port under Linux 12.10 [Skip 7.0.40 as already superseded]. He's got versions back to about Ubuntu Hardy.

If I gave the impression [or said] we were talking windows, sorry. Linux-64 is great, particularly with the VINA sciences. 60-70% faster than Windows.

Re: HCC1 Beta Test for Linux GPU (Issues Thread)

Thanks for advices. I'm under 10.04 64bits, and I will go for the 12.04 in a few weeks, and I will test with newer Boinc client version.

:-)

P.S. : I misunderstood your 'v7', I read Windows Seven, not v7 of Boinc, sorry.

Re: HCC1 Beta Test for Linux GPU (Issues Thread)

You are right, I just checked, some tasks are crashing with errors, and some don't.
This comes from the GT220 for sure...

I have to see how I can tell HCC to use only the GT430 :-/

edit : an example :

CL_DEVICE_NAME: Quadro FX 380 LP
CL_DEVICE_VENDOR: NVIDIA Corporation
CL_DEVICE_VERSION: 295.49
CL_DEVICE_MAX_COMPUTE_UNITS: 
CL_DEVICE_MAX_WORK_ITEM_DIMENSIONS: 3
CL_DEVICE_MAX_WORK_ITEM_SIZES: 512 / 512 / 64
CL_DEVICE_MAX_WORK_GROUP_SIZE: 512
CL_DEVICE_MAX_CLOCK_FREQUENCY: 1375 MHz
[...]
CL_DEVICE_COMPUTE_CAPABILITY_NV: 1.2
CL_DEVICE_REGISTERS_PER_BLOCK_NV: 16384
CL_DEVICE_WARP_SIZE_NV: 32
CL_DEVICE_GPU_OVERLAP_NV: CL_TRUE
CL_DEVICE_KERNEL_EXEC_TIMEOUT_NV: CL_TRUE
CL_DEVICE_INTEGRATED_MEMORY_NV: CL_FALSE
Estimated kernel execution time = 6.35754 [sec]
ERROR: Kernel execution time estimate too high, exiting.
10:10:49 (2788): called boinc_finish

Why does it see a Quadro FX instead of GT220 ???
You have the same kind of errors with your gt220 ?

Re: HCC1 Beta Test for Linux GPU (Issues Thread)

ubuntu 12.10 x64. ATI 7770. fglrx-updates installed from repos. client ver.7.0.28. Downloaded and installed latest AMD-APP SDK from
http://developer.amd.com/sdks/AMDAPPSDK/downloads/Pages/default.aspx
howto install it located here http://blog.markloiseau.com/2012/05/install-opencl-sdk-ubuntu/

So, in the begining I got computation error.

Starting BOINC client version 7.0.28 for x86_64-pc-linux-gnu
ATI GPU 0: Capeverde (CAL version 1.4.1741, 1024MB, 764MB available, 3200 GFLOPS peak)
OpenCL: ATI GPU 0: Capeverde (driver version 1113.2 (VM), device version OpenCL 1.2 AMD-APP (1113.2), 1024MB, 764MB available)
Requesting new tasks for ATI
Scheduler request completed: got 1 new tasks

Requesting new tasks for ATI
Finished download of X0960086731298200705111607_X0960086731298200705111607.zip
Starting task X0960086731298200705111607_3 using hcc1 version 708 (ati_hcc1) in slot 3

Then I manually deleted task with an error and after manual update (user request), I got number new tasks for ati.
Now I see additional task running (with "1 CPUs + 1 ATI GPU" text)

update1: some gpu tasks end with an error
update2: desktop interface responsiveness decreased sad

To get rid of that should I switch to latest catalyst 12.11 which is beta?
update3: currently I have 5% of errors for gpu tasks. And it seems like it's decreasing
update4: system hangs sometimes. It happens when gpu task tries to resume after suspend. But rather resuming works and gpu task is computed from where it had stopped due to suspend.

Re: HCC1 Beta Test for Linux GPU (Issues Thread)

I got also these problems with my new bought Radeon HD 6670! crying

I opened up a new bug reports about this behaviour:
https://bugs.launchpad.net/ubuntu/+source/boinc/+bug/1077316

So please add yourself to this bug and give a hand in solving this problem.

"no usable gpu found" problem is well known for years. And if you have ati you got that issue almost 100%. I decided not to wait for decision here. I install manually boinc to my home dir and add to "startup applications" '/home/BOINC/run_client --daemon' string.

Then to run boinc-manager I type

./run_manager

from /home/BOINC/ dir

Re: HCC1 Beta Test for Linux GPU (Issues Thread)

Yes, but i seems a quiet bigger problem, look at #6.

After stopping all processes GPU does not work correct!

But i will try an manually installation of BOINC and test this out.
Thanks for the hint.
