Abstract

The SB-PRAM is a shared memory machine which hides latency by simple interleaved context switching and which can be expected to behave almost exactly like a PRAM if all threads can be kept busy. We report measured run times of various versions of the MP3D benchmark on the completed hardware of a 64 processor SB-PRAM. The main findings of these experiments are: 1) parallel efficiency is 79% for 32 processors and 56% for 64 processors. 2) Parallel efficiency is limited by the number of available threads.
