Cache-Only Memory Access Model (COMA)
As we have considered earlier, shared memory multiprocessor systems can use cache memories with each processor for decreasing the execution time of a particular instruction. So in NUMA model, if we employ cache memories in place of local memories, then it turns into COMA model. The set of cache memories makes a global memory space. The remote cache access is too non-uniform in this model.
