Abstract: IBM has recently launched an upgrade of the communication subsystem of its SP2 parallel computer. This change affects the communication hardware (high-performance switch and interface adapters) as well as the communication software (MPI implementation). In order to characterize to what extent the execution times of parallel applications will be affected by these changes, a collection of benchmarks has been run on a SP2 with the old communication subsystem and on the same machine after being...

...completion time for Step 4 of the algorithm. Finally, we estimate the time in seconds to transfer this maximum number using the model of [11] for smaller messages (see Section 6.3: ff = 47 and = 0:0254) and considering a message of 8 bytes to request (suffix pointer plus...
