InfiniBand vs. iWARP--RDMA Technology Comparison
More InfoLess Info
This white paper paper compares various strategies for remote direct memory access (RDMA). RDMA technologies can boost network performance by offloading work from processors. Programs and interconnects that use RDMA provide access to memory directly without operating system or CPU intervention. Mellanox takes a look at two RDMA technologies—Infiniband and iWarp. The article covers Top500 World Fastest Supercomputers: Infiniband or iWarp, application performance and which of the two is indeed faster.
