Thanks, got the 128 core box back to running 50 threads. Still not where I need it to be, but much better than before.

Seems to be a limitation of the boinc_client program. Checked command line options, and there is one which seems to allow multiple clients, however, when I tried to run 2 instances of boinc_client, it just complained that one was already running, even with that option.

Did you make another directory location, and install Boinc in it, then run that instance with the allow allow multiple client? each instance will need to a have a different host id, etc, so you can't run a client multiple times from the same directory.

Seems to be a limitation of the boinc_client program.

Because it couldn't possibly be a limitation set elsewhere, or yet again a bad preference setting. Without messages what this BOINC does at such a moment, there's not much I can see about it either, but I can tell you that the BOINC client has no limitation on CPU cores it can detect and use.

As long as the hostID is seen as reliable, your work + additional work request is set to something high enough, and the project allows that much work to be sent to your client, it can stock up work and run it simultaneously. So perhaps it's a project limitation, or it's something else. Impossible to guess without you giving some message lines of a scheduler contact with the project, preferably with the <sched_op_debug> flag set on.

You may also want to read When requesting help on these forums for a clue of the bare minimum we like to get when guessing at answers, without constantly having to play 20 questions.

As for multiple_clients, and as Claggy asked, you did set them up with different data directories and when paired against a BOINC Manager, different port numbers?

Something like:
CD /D c:\Boinc1
"C:\Program Files\BOINC\boinc.exe" --detach --allow_multiple_clients --gui_rpc_port 31417 --dir c:\BOINC1
"C:\Program Files\BOINC\boincmgr.exe" /m /n localhost /g 31417 /p xxxxxxxxxx
CD /D c:\Boinc2
"C:\Program Files\BOINC\boinc.exe" --detach --allow_multiple_clients --gui_rpc_port 31419 --dir c:\BOINC2
"C:\Program Files\BOINC\boincmgr.exe" /m /n localhost /g 31419 /p xxxxxxxxxx

No, I wasn't aware that separate directories were needed. Ill try that and see if I can get it going at 100 threads instead of 50.

As for the host side, I know the host will support all 128 threads, as it was running a database engine prior to being replaced with a newer/larger box. So I do believe it's something on the application side, but since that includes all the application settings, there could be a limitation in those settings I haven't discovered yet. Ill try and read more about the various settings and what they control.

Tried multiple directories, but no luck. The second instance doesn't run.
I have also not been successfull in locating any option settings which limit the boinc instance to 50, so im thinking it may be an inherent limitation. Will have to ask on Boinc support forum to get more details on that issue.

Anyone know what the "failed" message is about? Does this have somthing to do with trying to run 2 boinc_client processes?

Ive been a bad boy and let this thread drift off topic.
The initial issue regarding GPU's is resolved. My 7850's are running, although VERY slowly compared to CPUs.

Ill take the cpu threading issue to a new topic.
