Moved Boinc vesion, confused about reinstalling op app's
Rob.B:
Thaks you for the link Richard.
Rob.
Rob.B:
Followed the instructions to the letter and blew away my Boinc Manager! Won't start properly, can't unintall, cant repair, sant shut the client. Well and truly screwed!
Tried butting back the pre op app structure, no go. Ended up having to physically delete both boinc directory structures, then uninstall, then reinstall. Now back at 6.6.20 stock apps but seeing only one GPU. I think I'll go back to 6.4.7 again. (This was my second try at movong to 6.6.20).
Thanks anyway.
Rob.
Rob.B:
Third time lucky, with a clean install I have followed the template instructions and now the AP's are running OP-APP and MB is running stock CUDA, but only one CUDA is being used (I have two).
I have tried amending this entry in the app_info file from one to two, but when set to two no CUDA work starts.
<coproc>
<type>CUDA</type>
<count>1</count>
</coproc>
I have even reinstated cc_config with an entry: <use_all_gpus>1</use_all_gpus>
No luck.
This seems far more complex than it need to be. Any ideas on this one?
Raistmer:
Don't touch <count> field. It's for another purpose.
What log of your BOINC client at startup?
Rob.B:
OK, reset that field.
The log shows 1 GPU, I downgraded back to 6.4.7 and it see's two GUP's again. Now back at 6.6.20 and only one GPU is recognised. It's all very strange.
I'm going to be working away for a week or two, so my wife will be keeping an eye on my server, so I'm going back to 6.4.7 until I get back.
