Well, this is the example newbies will follow when they want to write code using the same interfaces. Given the lack of documentation, we really depend on good examples for people (like me) who have never written code for any infiniband implementation. > Since it has no pipelining, its also not the best bandwidth benchmark.

Harping on the same theme as above, that might be an opportunity to hack something into an existing benchmark like netpipe or netperf. Ie provide an example of how to adapt an existing application to optimally use openib interconnect. thanks, grant _______________________________________________ openib-general mailing list [email protected] http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
