Abstract
In this work we study the effect of cache blocking and memory/thread placement on a modern multicore shared memory parallel system, the SunFire X4600 Ml, using the Gaussian 03 computational chemistry code. A protocol for performing memory and thread placement studies is outlined, as is a scheme for characterizing a particular memory and thread placement pattern. Results for parallel Gaussian 03 runs with up to 16 threads are presented.
