NUMA API

Are there any usr API that can control affinity etc/, from application level for x64 ? Somewhat similar to suse !

I might be missing something here, could not find any on psdk for x64.

Prokash,

just look in SDK/PDK documentation.

SetProcessAffinityMask(),
SetThreadAffinityMask(),
SetThreadIdealProcessor(),
GetCurrentProcessorNumber(),

GetNumaNodeProcessorMask(),
GetNumaProcessorNode(),
GetNumaAvailableMemoryNode(),
etc.

These functions are available for 32-bit Windows apps
and should be available for x64 apps too.

Do you need something else?

Dimitry,

Thanks for the info. I will surely look at them.

Specifically I’m trying to see how much is exposed to the user for managing
the cc-Numa(x64). I’m not quite up to the point of getting the dual-opteron
on x64 os, and found that the psdk for x64(native) may need to be unzipped
on 64bit os.
Getting the drivers downloaded, then I will get it up and running soon. On a
Dell(x64), I was lucky not to get any drivers, but that one was
uni-processor.

For now, this is enough ptr.

Thanks again.
