SELECTION OF MESSAGE PASSING COLLECTIVES IN PRESENCE OF SYSTEM NOISE

摘要

Consideration of system jitter in selecting a “message passing collectives algorithm” used in a message passing interface. A set of multiple message passing collectives algorithms are ranked against each other with at least some consideration of relative jitter-related performance as between the algorithms. The consideration of jitter includes consideration of “system jitter” (OS jitter and/or network jitter). In some embodiments, multiple rankings are performed for different levels of system jitter.

1. A method comprising:
providing a plurality of message passing collectives algorithms; evaluating each algorithm of the plurality of message passing collectives algorithms for performance when subject to at least one type(s) of jitter to obtain jitter evaluations; and ranking the plurality of message passing collectives algorithms relative to each other based upon the jitter evaluations to obtain a first ranking.
