The initial patch submitted to Andrew didn't include the NUMA support hence it is not expected to work on NUMA. We are testing the DISCONTIG_MEM patch, we will submit after finishing the testing. > > 2) AMD64 is not supported - i can't use my Opteron machine. > > 3) ppc is not supported - i can't use Power3 and Power4 machines. First set of patches are only meant to support 32bit x86 platform. Plan is to support Opteron and other platforms after stabilizing the initial patches. We are working on porting to AMD64 and PPC platforms. > > So, I can only try it on non-NUMA i386 smp boxes. I have few of > those to try. I will give an update next week on my testing. You can try on i386 UP and SMP boxes.
