Abstract
A cache coherent distributed shared memory multi-processor computer system is provided with a cache-flushing engine which allows selective forced write-backs of dirty cache lines to the home memory. After a request is posted in the cache-flushing engine, a 'flush' command is issued which forces the owner cache to write-back the dirty cache line to be flushed. Subsequently, a 'flush request' is issued to the home memory of the memory block. The home node will acknowledge when the home memory is successfully updated. The cache-flushing engine operation will be interrupted when all flush requests are complete.
