United States Patent Application

View the Complete Application at the US Patent & Trademark Office
Methods, apparatus, and products are disclosed for performance testing of message passing operations in a parallel computer, the parallel computer comprising a plurality of compute nodes organized into at least one operational group, that include: establishing, on a compute node of the operational group, a number of measurement iterations for testing a message passing operation, a first group of the measurement iterations designated as warm-up iterations, and a second group of the measurement iterations designated as testing iterations; for each measurement iteration: executing, by the compute node, the message passing operation under test, and measuring, by the compute node, an elapsed time for only the execution of the message passing operation under test; and determining, by the compute node, a performance result in dependence upon the elapsed time for each measurement iteration designated as one of the testing iterations.
