Optimal performance is accomplished using the tool dplace .
This eliminates the potential for poor performance resulting from multiple threads executing on the same processor. As with a single dedicated job, for best performance, it is recommended that you do not use all the processors on the system. Leave 1-2 processors free for use by the operating system and other system processes. Note that for benchmarking runs, SGI recommends running jobs one at a time rather than using dplace to run multiple jobs at a time. The section Non-MP Library Programs and Dplace in Chapter 8 of the SGI manual Origin2000 and Onyx2 Performance Tuning and Optimization Guide also has detailed information on dplace.
