Description This work presents a low-level communication protocol for Myrinet, which offers reliable data transmission at network interface level. The protocol is used within the ParaStation2 system, a high-performance cluster for parallel computing. Although most projects using Myrinet assume the hardware to be reliable, there is strong evidence that this assumption does not hold and reliable data transmission has to be ensured using an appropriate protocol. ParaStation2 exploits Myrinet's programmable network interface (NI) to implement link level flow control based on an ACK/NACK mechanism with timeout and retransmission. We describe the design and implementation of ParaStation2's transmission protocol and we evaluate it performance by comparing it to two similar protocols offering reliable data transmission, namely AM-II from Berkeley [CMC97] and VMMC-II from Princeton [DBL + 97].
