Many existing clusters use inexpensive Gigabit Ethernet and often have multiple interfaces cards to improve bandwidth and enhance fault tolerance. We investigate the use of Concurrent Multipath Transfer (CMT), an extension to the Stream Control Transmission Protocol (SCTP), to take advantage of multiple network interfaces for use with MPI programs. We evaluate the performance of our system with microbenchmarks and MPI collective routines. We also compare our method, which employs CMT at the… CONTINUE READING
