Wus are very long to complete with Win Seven 64 bits, near the double time compared to 6.06 app under Linux 64 for equivalent amount of points.

Is there a way to make it work better ? (Is Sync Swan switch useful or not with this new app?)

For Information of linux users, to create proper launcher that stop and restart Boinc when "gpu missing" appears in its messages lines, the command line is :


sudo /etc/init.d/boinc-client restart


Don't forget to execute it in a terminal or it could not work as wanted.


Here is the stats i get crunching under Xubuntu :

<core_client_version>6.10.17</core_client_version>

Average 8ms/step with stock gtx 470 and Core 2 quad Q6600 runing 3.6Ghz 450 Fsb X 8 watercooled.

90°C for gpu temp 38°C for hotest core of Cpu at ambiant 27°C.

No crash since new Wus a couple of days. All runs fine for me here, yesterday i reached the 120 wus/day quota near 12H crunching since 00H00. Fermi works well on linux x64!!!

Does not work for me but a launcher restarting boinc client does actually the job.

Xubuntu permit to compute really faster, according to my personal tests, than Ubuntu or kubuntu. Give it a try.
4) Message boards : Graphics cards (GPUs) : What's the size of wus? (Message 17110)

Because of my limited bandwidth, i would like to know the size of wus for fermi cards on windows and linux 64 bit. (i reach easyly the 120 wu/day quota on xubuntu system then often switch to seven to complete some more wus)

I know the size is not always the same regarding the type of wu, so an idea about average size for both OS will be good for me to know about. Thank you by advance for replies, and again sorry for my approximative english.

I have the problem after reboot where my gpu is not found, then i found a workaround with two shortcuts on my desk, one to stop client, the other to restart it.

No "panache" here but it does the job.

Finally, I opted for the Ubuntu distro, mainly due to install via wubi which allows Windows to coexist just seven and Linux without having to suffer the burden of Grub 2.

My first workunits were calculated in 425 seconds or less, I'm pretty happy with the results.

Wubi is really an extraordinary idea for a setup like mine, again, everything here has installed a ssd, I did not suffer loss of velocity on my disk access, the best of both worlds ...

Thank you all for useful informations. I'm going to wait a bit before crunching under Linux, i'm glad to discover new OS via GPUGRID participation.

Again thx guys.

PS: Do you think Open suse 11.2x64 is a good distro to crunch and learn about linux world? This one is the one i prefer after testing Ubuntu and derivated included Mint, Mandriva and Fedora. What is your advice?

Is there any solution available to make GPUGRID function with fermi cards in Linux environement?

All Wus i got in linux (6.04) crashed. I tried with Ubuntu/Xubuntu/Kubuntu and Suse in their last x64 flavours.

I'm a linux newbie as i just want to use it for crunching faster.

Lot of computation errors since buying this fermi card.

What prefs for this project to run as expected with this card?
