(mine is > pentium D processor) NUMA (Non-Uniform Memory Arcitecture) has nothing to do with the processor but everything with the memory architecture. You can build NUMA systems using a Pentium D processor, but SMP systems are far more common. OTOH, some processors like the AMD Opteron family have a built-in memory controller which makes a multi-processor Opteron system automatically a NUMA system. All 2.6 kernels support NUMA systems. > When I'm using "numactl" command, it gives an error that "This system > doesn't support NUMA policy" Then your system indeed doesn't support NUMA.
