Abstract
Recently, NetEffect Inc. has introduced the first and only iWARP­enabled 10-Gigabit
Ethernet Channel Adapter. This white paper presents the performance of the NetEffect PCI
Express 10-Gigabit iWARP Ethernet adapter at the NetEffect verbs layer and the MPI
implementation. At the verbs layer, our evaluation includes the basic latency and bandwidth
tests for both Send/Receive and RDMA write operations, as well as the cost of memory
registration. At the MPI level, we present the basic latency and bandwidth, aggregate
bandwidth, hotspot bandwidth, and the computation/communication overlap ability for the
NetEffect MPI implementation.
