Well I'm sure glad I didn't build one of the new 44C/88T machines. Besides having to hock my soul to pay for it I would have really been PO'd when I couldn't use all of those suckers =))Quote:

Since JPM weighed in then that is the definitive answer. I won't argue with that boy :D
Okay. But what does that mean exactly? You need to configure DIMMs differently? Run dual VMs of windows somehow? I read the wiki about NUMA, but it really doesn't explain the part about how you implement it, or work around it, or turn it off.Quote:

When NUMA kicks in, it assigns groups of 64 threads to a node (by default). You can have more than 1 node going, but the way it works is that a program that launches another program can only launch that other program into the same node it resides in, meaning BOINC cannot use more than 1 node. It can see all threads over 64, but can't assign WUs to them.
If using Windows, a VM would be the way to go. Or you could turn HT off. Or figure out how to run 2 instances of BOINC at the same time, assigning 1 to node 1 while the default remains in node 0. Or beg the BOINC devs to code for more than 1 node.
Or just use Linux ;)
