DASH uses a directory-based coherence protocol with point-to-point messages.ĭirectory-based cache coherence is essential to modern high-performance computers (supercomputers), although we have evolved to more complex directory structures. Data has to be communicated between them. However, these have multiple separate memories. Uniprocessors can only handle small problem sizes, so the future lies in multi-processor systems.
