Experiences here, please.

Ubuntu 14.04.1 - Nvidia driver 343.22 - BOINC Client 7.3.15 - 1 GTX 770 + 1 GTX 750 Ti - Both working on acemdshort 8.46 (CUDA 6.5)

Scheduling questions :
1/ My account is set up to get only acemdlong (no acemdshort or acemdbeta), why did I get an acemdshort ?
2/ My system is GK104 + GM107, so based on http://www.gpugrid.net/forum_thread.php?id=3874 I was thinking to get CUDA 6.0 application ?

* If you have a GM204 you will get a CUDA65 application, or nothing if your driver is too old
* If you have a GM107 you will get a CUDA60 application, or nothing if your driver is too old
* If you have a Fermi or Kepler you will get a CUDA60 application, or CUDA42 if your driver is too old

Regarding performance, nothing special right now. GM107 and GK104 appear to crunch well with CUDA 6.5 :)

64-bit linux mint 17, GTX980, nvidia driver 343.22

finished NOELIA_SH2 WU:

http://www.gpugrid.net/result.php?resultid=13168490

Everything ok so far.

64-bit Linux Ubuntu, Driver 340.24.

Finished 2 on a GTX 770 and they validated.

One more under way on a GTX 660ti and one more on a GTX 770.

Everything looks normal so far.

Nicolas,

You got a short because there's no long app yet.

Matt

Some data. In windows setting SWAN_SYNC=0 results in 100% CPU usage of one core. It doesn't seem to work in Linux (24-50% CPU usage with or w/o env variable)

The trend for the 980 is slower on Linux vs Win 8.1

I may try rolling back the driver on the machine with the 780Ti to see performance of the Cuda 6.0 app.

I couldn't get the formatting quite right below but you should be able to figure it out I think.

This Error was due to me rolling back the nvidia drivers on my 780Ti.

I'm testing NOELIA_SH2 WUs using the cuda 6.0 app.

I couldn't get the formatting quite right below but you should be able to figure it out I think.

You should use the "pre" tag instead of "code", and white spaces instead of tabs.
It is also practical to abbreviate the OS name, just like you did it with Windows.

Thanks for reformatting the table and the format suggestions. I'll give it a go next time.

Are we ready to move to the "long" WUs?

Is SWAN_SYNC functional in the new cuda 6.5 linux app?

I added SWAN_SYNC=0 in /etc/environment and printenv SWAN_SYNC returns the value 0.

CPU usage is still quite low though.

On Linux you need SWAN_SYNC=1

Matt

On Linux you need SWAN_SYNC=1

Matt

I'm seeing similar CPU time per WU whether I set SWAN_SYNC to "0" or "1" on the 780Ti or 980 (different machines).

On win 8.1, I saw a dramatic increase in CPU time per WU when I set SWAN_SYNC to "0".

BTW, for linux users using recent nvidia drivers, if you set coolbits to 12 you have more monitoring info (GPU utilization, PCIe bandwidth utilization, memory usage), manual fan control and overclocking/underclocking options.

http://www.phoronix.com/scan.php?px=MTY1OTM&page=news_item

Here's the device section of my xorg.conf file:

Section "Device"
Identifier "Device0"
Driver "nvidia"
VendorName "NVIDIA Corporation"
Option "Coolbits" "12"
EndSection

Well, don't worry about it too much. Provided the cpu's not over-subscribed there's negligible performance degradation.
