AK V8 + CUDA MB team work mod

[jj_glos]

As expected it only uses 1 GPU on multi GPU setup...
So far so good though...

Anyone got any ideas on how to get 2 GPU going? It pains me to leave one idle...

I'm getting lots of computation errors.  Cuda app running fine + 4x AK V8 running fine, but fifth AK V8 will start and stop at 8-9 seconds with computation error.  Fifth AK V8 starts again and repeats.  Computation errors stack up quick!  I'm doing SETI and SETI Beta, but only installed package to setiathome.berkeley.edu folder not setiathome.berkeley.edu_beta folder.

Hi there.
Some errors from me:

Yes.
Use V7x package. It relies on BOINC GPU scheduling and will use both yours GPU. But will not do SETI MB on CPU.
But you can do SETI AP on CPU, with opt app too.
So this V8 "team" mod doesn't make V7x packages obsolete, it just provide another way  - in one config some way will lead to better performance, in other configs it will be another way.
So, for dual/many GPU configs I strongly recommend to use V7 of my package, not V8 one.

Could you provide link on that host, please?
5th AK v8 (first one, actually) shouldn't take 8-9 seconds. It should take 0 seconds to pass control to CUDA MB....

Yes, this is known inherently error of CUDA MB (but was unknown if this bug still with us or not).
Probably you can do nothing to avoid it, just kepp crunching - I hope this error prety rare. Thanks for report (I passed bug report to developer).

I tried to install your version 8aon my quad core, but all the units that went to the gpu all were getting computation errors, so I removed the opt app to just let the defalut process for now.

Here are two of the errored out tasks:

You didn't install it correctly, reinstall. And try to describe sequence of operations you did first time.

I downloaded this file:  Raistmer's_opt_package_V8a_CPU_GPU_team.rar

Stopped BOINC and then ran net boinc stop to make sure nothing was still running.

Copied the contents of the download to ....BOINC\projects\setiathome.berkeley.edu

Made the cc_config.xml file and placed that in the appropriate spot.

I then restarted BOINC and watched all the units hitting the gpu error out.  None of the units processing via the cpu were erroing out, just the gpu ones.

As for reinstalling it, that will have to wait until I get home from work.

[Raistmer]

Looks all done right.
But, it seems you use service BOINc install (net stop boinc - it's for stopping service). and pre-V6 BOINC, V6 BOINC use BOINCdata folder instead BOINC folder. IS it true?

Was running BOINC version 5.10.45, then 6.2.19 and now have installed version 6.4.5.  When I installed 6.2.19 and 6.4.5, I chose advanced and then Protected application execution.  When installing newer versions, I just stopped BOINC and then installed the new version using the defaults for path.

This machine is running Vista Home Premium 64 bit.  The actual path is C:\Programdata\Boinc\projects\setiathome.berkley.edu

protected execution=service execution (almost).
But under Vista service BOINC can't get access to CUDA-capable GPU. It seems you should try to reinstall BOINC first.

Ok, 180.xx drivers are required.

If it cant access the CUDA-capable GPU when run as a service, then why is it happily chugging away on CUDA apps when using the standard Berkley apps?  Or is it when BOINC sees the app_info.xml file then it can't access the gpu?

Edit:

On second thought, I don't think the computer has been rebooted for some time, so BOINC may not actually be running as a service right now.  I'll also verify what version of video driver is installed.
