Cache only memory architecture
From Wikipedia, the free encyclopedia
Cache only memory architecture (COMA) is a computer memory design used in multiprocessors composed by caches only. It was found that NUMA machines have a set of local copies of data in cache and also have the same data in a distant memory, which can be eliminated using this method. In this method, what is kept is the cache which does not have a permanent home, since there is no memory to fall back on.
