Someone more familiar with ipoib needs to respond regarding those changes. For rsockets, please make sure that you've pulled the latest code. You can improve the performance by adjusting the QP size and send/receive buffers, which can be done through config files. I started an rsocket man page that describes the files that I just pushed out to my git tree. - 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
