Title: constrain an app to one core?
OK, I have a system made of three applications running simultaneously, one of
them servicing a USB device, the other two are for UI.
They all send messages to one another, sometimes rapidly, using a shared
memory mechanism.
There is some flaw in my architecture that causes intermittent failure on
some multi-core systems, both Mac and PC (same 3-process architecture
is used there).
I worked around the issue on PCs by constraining the 3 processes to all
run on the same processor or core.
Is there a way to do this in OS X? Processor Affinity?
thanks.
