| | | Assessing Single-Message and Multi-Node Communication Performance of InfiniBand
(In Proceedings of IEEE International Conference on Parallel Computing in Electrical Engineering (PARELEC'06), presented in Bialystok, Poland, pages 227-232, IEEE Computer Society, ISBN: 0-7695-2554-7, Sep. 2006)
Abstract We present a micro benchmark suite to evaluate
InfiniBandTM implementations with regards to single message performance and the addressing of many hosts. We
use a 1:n communication pattern to assess the latency and
bandwidth for all different combinations of InfiniBandsTM
transport services and functions. The results gathered in
this study are used to optimize MPI collective communication operations where 1:n communication schemes are
not used widely today. We show that applications as well
as collective algorithms can benefit from sending multiple messages in a single round. Moreover, the results will
be used to choose the transport service and function to
develop InfiniBandTM optimized collective communication
functions. Our study compares all available transport options and shows that single packet sends can be very expensive compared to multi packet sends.
