Hi Guys,

Just a line to say we've got our first GTX750Ti card up and running. The performance out-of-the-box matches a GTX480. We'll have a public app for GPUGRID just as soon as CUDA 6.0 is publicly released, which will probably happen at GTC at the end of the month.

Matt

a cuda6 application will be available asap. Minimum driver required 334.21.

Can you please post a few results (time) how it performs here ?

I assume "up and running" means that it works with some sort of your beta CUDA 6 app...

Thanks Alexander,
That could provide a daily RAC of ~253,000 (while crunching Einstein iGPU WU's) or around 278,000 if not.

Peter_M: You should be getting WUs like any other client...

Has the linux app already been updated for Maxwell? Otherwise the recent scheduler changes may prevent sending the wrong app. Or something simply went wrong with that scheduler fix.

There is only a CUDA6 app for Linux in the Beta queue,

Linux running on an AMD x86_64 or Intel EM64T CPU 8.11 (cuda60) 15 Mar 2014 | 0:07:21 UTC

However, going by the Server status page there are no Beta tasks,

ACEMD beta version 0 0 0.00 (0.00 - 0.00) 0

...So there are no CUDA 6 tasks for Linux!

Correct - I need to build a CUDA 6 app for Linux.

Matt

Linux app CUDA 6.0 is now available for cc5.0 / GTX750 etc.

Matt

Huh. That's unexpected. What driver version do your machines have?

Matt

One of the problems may be that BOINC for Linux never seems to have been able to extract the version numbers from CUDA drivers and report it to the servers.

With the recent drivers, performance can be capped due to a lack of GPU utilization; I'm presently running a GERRARD Long run task on CUDA 6 (albeit on a GTX770 and W7) and the clocks are 1045MHz. Power is at 40%. It's normally OC'ed to ~1250MHz. Even with only 3 CPU threads in use for CPU projects and the GPU Utilization rising to 80% the GPU remains in that non boost clock rate (it drops but doesn't rise). It's a known issue, but it's hard to spot - might not happen for days if you only receive some WU types. So far I have only seen this on the first GPU, and rarely. This driver 'feature' might also be applicable to Linux.

I'm using 331.49 on Linux with a GTX670 and a GTX660Ti. I get the odd failure on that system, but so far I've not seen any issues with the few tasks that ran on CUDA6. Recently completed a Gianni WU using v8.20 (cuda6.0), presently running a NATHAN_KID using 8.20 (cuda6.0).
Going by NVidia X server the GTX670 GPU clock varies from 1071 to 1110MHz (with Prefer Maximum Performance selected).

I have not received any cuda6 WU's on my other Linux system with an earlier driver.

Was going to suggest using the Beta queue, but at least they won't all fail overnight!

8.21 also failed on my Ubuntu 13.10 system (331.49 drivers and either or both of a GTX670 and a GTX660Ti). Failures were quick:
