STREAM "Top20" results

This table shows the "Top 20" shared-memory system results, from either the "standard" or "tuned" category. This is intended to be a "show-off" table (similar to the LINPACK NxN benchmark), so code modification (including assembly language coding) is acceptable.

Here "shared-memory" means that all memory is transparently accessible to all processors using standard load and store operations.

The table excludes:

cluster results
"MPP" systems, such as the IBM SP and Cray T3D/T3E
