Both libibverbs and librdmacm provide sample programs, and you could also look at some of the perftest samples. The simplest of these for RC QPs is probably the rdma_server/rdma_client samples with the librdmacm, but these make use of newer APIs. For UC QPs, you would need to look at libibverbs. UD QPs are setup differently, but both libibverbs and librdmacm have samples. There wasn't enough context provided in the code snippet for me to see the cause of the crash. - Sean -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
