This report describes the Myrinet interface card, a card that interfaces the Hewlett-Packard 9000/J200 workstation to the Myrinet local-area network, and HP-LAM, an implementation of Generic Active Messages (GAM) on that platform. It describes the performance of HP-LAM in terms of LogP parameters and in terms of execution time for the Split-C application radix sort. It shows how HP-LAM's performance is limited by inefficiencies in transferring data over the peripheral bus. It compares the performance of HP-LAM to that of Sun-LAM, a similar implementation of GAM on the Sun Microsystems SparcStation-20 and Ultra-1 workstations. The comparison shows that the performance of HP-LAM is comparable to that of Sun-LAM on the SparcStation-20 but is poorer than that of Sun-LAM on the Ultra-1.
