Non-Uniform Memory Access Model (NUMA)

In shared memory multiprocessor systems, local memories can be joined with every processor. The group of every local memories form the global memory being shared. In this way, global memory is dispersed to all the processors. In this  the access to a local memory is regular for its corresponding processor as it is involved  to the local memory. But if one reference is to the local memory of several other remote processor, then the access is not uniform. It depends on the place of the memory. Therefore, all memory words are not accessed equally.
