Unable to download new WU's

[craiginsd]

For some time now, my 8-core Mac Pro has not been assigned any projects. I tried changing the CPU setting from -1 to other positive values, but to no avail. Also tried reinstalling FAHControl 7.4.4, but still nothing. Any ideas?

Here's the front end of the log file, in case that helps.

Mod edit: added Code tags to log file

Change the -1 to 6. There are no more WUs being assigned that support 7 threads which is what you'll get with an 8 threaded CPU and a GPU.

[Joe_H]

I see where you changed the CPU count to 2 and still did not get a WU assigned. However the slot never paused, so it is possible it was still trying to get a WU based on the -1 resulting in a request for 7 CPU threads. My suggestion would be to pause the folding slot and check the log to make certain the download attempts also stopped. Then change to a CPU count of 6 or another number besides 7 and start the folding slot again.

If the slot does not stop attempting a download, you may need to restart the FAHClient process. It can be done from the command line, but is easier to do by rebooting your Mac Pro. First change the CPU setting before the restart.

[toTOW]

Since you don't have a supported GPU to drive in your Mac, you can also choose to set it to 8 threads.

[craiginsd]

Thanks guys! Setting the CPU to 6 solved the problem! Many thanks again!!

[toTOW]

If you don't mind the heat, setting to 8 will work too with better performance ...

[ChristianVirtual]

Keep 6 as setting, problem solved

[Joe_H]

Change the -1 to 6. There are no more WUs being assigned that support 7 threads which is what you'll get with an 8 threaded CPU and a GPU.

Was this problem ever solved to where we can use the "default, -1" setting, or must we still use the 6 setting???
Thanks.

A permanent fix will require an updated client. Dr. Pande has announced that was being worked on, but no date has yet been announced for release. Before full release there will be a public beta of a new client based on past releases. The V7 archive topic - viewforum.php?f=90 - has the discussions of the prior public beta tests.
