Add to ORKGWe have implemented eight of the MPI collective routines using MPI point-to-point communication routines with algorithms designed to be efficient for large messages. The performance of our implementations of these collective routines is compared with the vendor implementations on the Cray T3E-600, the Cray Origin 2000 and on the IBM SP. Many of our implementations significantly outperformed vendor implementations on the T3E and the Origin 2000. On the SP, only our implementation of the broadcast significantly outperformed IBM's implementation
