Sean/IB experts:
I'm running a version of rdma_bw from src/userspace/perftest that I ported to utilize the RDMA CMA library for connection setup (stay tuned for a patch to offer this to the trunk). The CMA version exchanges the rkey information during RDMA connection setup using private data. I noticed that over IB the private data length received is != to the size of the private data submitted by the application. I send 24 bytes both ways and always get 56 bytes in the RDMA_CM_EVENT_CONNECT_REQUEST event and 196 bytes on the RDMA_CM_EVENT_ESTABLISHED event. The first 24 bytes, however, are correct so the data is being exchanged. Over iWARP, the lengths are 24... Is this a bug in the CMA or IB CM? Thanks, Steve. _______________________________________________ openib-general mailing list [email protected] http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
