Is there a way to control the numa settings on the iMac (Core i7), OS X 10.7.3? MacPorts doesn't have numactl and tbb/openmp are both slowing down since the memory is allocated incorrectly.
Does Lion even support NUMA ?
For Snow-Leopard, I thought, there was no NUMA support. German article as source.
I could not find a source for NUMA support in OS X, thus I would say that there's as well no way to control the NUMA-settings ;)
This Intel document states:
No OS X mentioned.
