Comparing Ethernet and Soft RoCE for MPI Communication
Journal Title: IOSR Journals (IOSR Journal of Computer Engineering) - Year 2014, Vol 16, Issue 4
Abstract
Abstract: RDMA has pleasant consideration in the late 1990 when the Virtual Interface Architecture was introduced. This growth has accelerated with the introduction of Open Fabrics Alliance’s (OFA’s) Verb Interface. The stability & independence of OFA verb interface facilitated significant growth of software applications that exploit the benefits of RDMA. RoCE is an emerging trend that can be made to work on the Ethernet infrastructures. In this paper, we evaluate the Linux cluster, having multi nodes with fast interconnects i.e. Gigabit Ethernet & Soft RoCE and evaluates its performance using IMB and OSU Micro Benchmarks. A comparison between the IMB and OSU Micro benchmark is done and our results shows that IMB Benchmark is performing better in case of collective Benchmark class as OSU Micro benchmark is performing better in other classes of benchmark.
