| Explain Optimizations: | ||||
| STREAM: Aligned the data to cache line boundaries and added no_cache_alloc directives. Single cpu RandomAccess: Change vector length to 1024 and added concurrent directive. MPI RandomAccess: Changed distribution so all processors have equal number of elements except last cpu, this eliminated the need for a if test. Implemented "Extra Buckets" to vectorize. | ||||
