1) Message boards : GPUs : Has BOINC 7.12.1 broken NVIDIA detection? (Message 87775)

An update on this ....

Turns out that the problem was not BOINC, Windows or Nvidia.
I run the BOINC client under BoincTasks, a (normally) very nice third party tool that makes it easy to monitor several BOINC computers (I run 2-4 so this is useful). (If anyone is interested, you can get it at https://efmer.com/boinctasks-how-to-start/.

But .... I have also updated BoincTasks; same day as updating BOINC.

Interestingly, if I start the BOINC client from BoincTasks, BOINC does not find my GPUs. But if I start the local instance from BOINC Manager, the BOINC client _does_ find my GPUs. This appears reproducible on my machine.

So for anyone else seeing a similar problem recently; if you're running BoincTasks and have recently updated to v 1.75, maybe that's the issue. In the mean time, try starting BOINC with BOINC's own manager; it may behave better. And starting BoincTasks once the client is runing causes no trouble as long as you don;t stop and restart the client from inside BoincTasks.

Did you get the "updated" drivers from the Nvidia website?


Yes; driver update was direct from geforce.com.

... and a clean install.

Just installed BOINC client version 7.12.1 for windows_x86_64.
BOINC can no longer find my two NVIDIA GPUs; both are now reporting as 'missing'.
Restarting both BOINC and windows is ineffective.
Have updated NVIDIA driver to 398.82: still no luck.

System is windows 10 pro build 1803

Seems to be associated with the new BOINC version, but is this just me or a general problem?
5) Message boards : BOINC client : Boinc 7.6.22 only using 1 cpu core since win 10 update (Message 66597)

This issue seems to have resolved itself after a couple of days crunching; there seems no further need for discussion.

Just updated Windows 10 64 bit to latest (Nov 2015) version. Also updated BOINC to 7.6.22. Neither Rosetta, Einstein, nor WCG now use more than 1 of my two cpu cores. Yesterday they happily used both. And backing down to prev Boinc version does the same thing...

Any ideas why this might change?

NB: Also running 2 GPUs - a GTX 750 and GT640. Both working OK though the win 10 update needed a clean nvidia driver install to get open L back
7) Message boards : Documentation : Recent Average Credit description incomplete (Message 54924)

Looking at the BOINC wiki at http://boinc.berkeley.edu/wiki/computation_credit, I think the RAC description must be incomplete. It tells you only that RAC decreases by a factor of two every week - but it doesn't tell you how it's calculated to start with. I can _guess_ that it might be a daily moving average with an exponentially decaying weight - perhaps a weight that changes daily such that it halves over 7 days.
But that's a guess, and one which would imply that RAC could never be zero.
It'd be nice if the wiki said exactly how RAC was calculated.
