V10/11 of modified SETI MB CUDA + opt AP package for full multi-GPU+CPU use

<< < (7/80) > >>

Raistmer:
See first post, it stated as clearly as I could formulate that.
Here I better describe why it should be so.
In team mod BOINC doesn't know at all that some of apps it controls using GPU/CUDA.
It manages all applications as CPU ones. That is, it will run only ncpus copies of AK_v8 for example. But you need to take all cores and all GPUs busy, that's why you need number of started by BOINC apps to be NUMBER_OF_CORES + NUMBER_OF_GPUs in V10 packs.

Jason G:
So.... not advised to run with current Astropulse only work climate then, lest you get NumGPUs over subscription... right?

Kashra:
I just tried to install V10a x64 build on my XP x64 but it did not work.
I alway get a computation error.

Here is what I did:

Installed Boinc 6.4.5
Let Boinc fetch standard app + WUs
stop Boinc Service
place the files from the V10 Package in the Project directory and setup the cc_config.xml for 5 (4CPU + 1 GPU) and placed it in the main Boinc "user" directory.
start Boinc service
Both APPs Astro+Seti produce only computation errors all the time but I donīt know why.

Any idea what might cause the error?
The stock version runs without errors.

My system specs:

Intel Q9550 CPU
1x Nvidia GTX280 with 182.06
8 GB DDR-2 Ecc Ram
Windows XP x64 SP2
Boinc 6.4.5 service installation

Richard Haselgrove:
It might be easier if you told us what the error messages actually said.

The strong, silent type ;D There's a Kashra at SETI who runs host 4493623 - Q9450 and GTX280.

The error message (consistently) is

"Es gibt keine untergeordneten Prozesse, auf die gewartet werden muss. (0x80) - exit code 128 (0x80)"

  awww, without knowing what that is saying, it still 'sounds' rather coarse. [Hopefully Urs or Crunch3r might rock up, and make more sense of it]
