6.04 runs ok on my hosts but uses 100% cpu so I have elected not to run them.

Are you completely mad? Run them, they are not there to look at. They run 30% faster than the other tasks (that have run out).

Let me put this another way.
My highly overclocked i7 does about 1/5th the work of a GT240 (under windows). A GTX260 does about twice the work of a GT240 and a GTX295 does twice the work of a GTX260. So a GTX295 does 20 times the work of my i7.
Your GTX260s would do 13 times the work of an i7 under Linux!

- Give up one CPU core - you have quads and GTX260's!

I even sack a CPU core under Windows, just to facilitate GPUGrid even when it does not need one full core. It's worth it for me using Windows never mind linux!

BTW this is Way OT.

Well I ended up throttling back CPU utiliz to 80% on 1 machine, the other i didnt touch, but I pointed them both to 'work' to pick up some ver2 WUs (maybe). I now have 2 6.04 WUs running and well past the 2sec cpu mark, so I guess, i will kick back and monitor for a few days, see what happens w/ no twiddling for a couple days, be back in a few I guess

Paolo Biagini,
Do the same, select to only run ACEMD tasks.


To change account settings:
Goto Your Account, GPUGRID preferences, Edit GPUGRID Preferences,

Alter the Application versions as follows:

Run only the selected applications
ACEMD: YES
ACEMD ver 2.0: no
ACEMD beta: no


OK, I try it.
bye


NOT WORK IN ANY WAY :-(

Hi Paolo, it took me a few days to get my Linux boxes dialed in to run 6.04 WUs. I have now got 6 validated vs 1 errored out, and 7 more running/queued to go. Let me backtrack, maybe you will spot a prob on yours. I had to throttle back CPU utiliz on one of mine under BOINC prefs, from using 100% CPU back to 80%. Your own earlier post showed your single 6.04 successful run, confirms my work, these 6.04 linux GPU runs are real CPU hogs vs a windows GPU WU, although I have not a clue why a GPU linux WU should require nearly a sec/CPU for the entire run time in secs, while a windows seems to need 10% or less CPU for its GPU run to complete. End result, try freeing up CPU cycles from other projects. See if that helps.
If you dont have the latest/greatest (I assume) Nvidia drivers installed, it was another upgrade for me to get the 6.04 WUs to run clean, you will want to be able to display the NVIDIA X server settings from the OS to confirm good install, not to worry if BOINC still cant detect it, the WU's can tell the diff and were not running from backlevel drivers. HTHs

Everybody who responded to thread, I really had to bang all of your observations/suggestions together in order to get this project back on track/ functional. Thanks, Paolo check back if u r still stuck
