| 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 to use UPC version FFTs: Added directives to vectorize. Collapsed some loops. | ||||
