Sample sort was implemented using Split-C [14] and run on a variety of machines and processors, including the Thinking Machines CM-5, the IBM SP-2-WN and SP-2-TN2, and the Cray Research T3D. For every platform, we tested our code on six different benchmarks, each of which had both a 32-bit integer version (64-bit on the Cray T3D) and a 64-bit double precision floating point number (double) version.
