Abstract
In this paper, we have focused our work on memory accesses behavior over a AMD Opteron cache coherent Non-Uniform Memory Access (ccNUMA) platform with multicore processors. We investigated three types memory operations: threads accessing local data, threads not firing at each other and threads firing at each other. When the system was idle and not idle, We compared and analyzed the performance of the three cases and we have the important conclusion about the threads accessing to the memory.
