Abstract
It is important to Choose a good data distribution to the performance of applications on Non-Uniform Memory Access (NUMA) shared memory multiprocessors. In this paper, we have investigated memory accesses behavior over a AMD Opteron cache coherent Non-Uniform Memory Access (ccNUMA) platform with multicore processors. We get important conclusions that it is important to keep data local on node where it is being accessed and it is important to avoid sharing of data between threads running on different cores.
