Mulch-core processors today have two or four cores. When core counts hit 16 or 32, we will call these many-core processors. When core counts get that high, the connections that hook cores to each other, and cores to memory, will change. Non-uniform memory access (NUMA) is one such change in computer architecture (it is also in some multi-core systems). A lot of frustration can be avoided by being sure that your program designs, and the tools you use, are ready to "forward scale" to many-core processors.
