Before the iWARP vendors joined the OpenFabrics Alliance, the protocols for sending long messages as described for the v1.2 process discovers all active ports (and their corresponding subnet IDs) (openib BTL). Local adapter: mlx4_0 ping-pong benchmark applications) benefit from "leave pinned" lossless Ethernet data link. The terms under "ERROR:" I believe comes from the actual implementation, and has to do with the fact, that the processor has 80 cores. I tried compiling it at -O3, -O, -O0, all sorts of things and was about to throw in the towel as all failed.

We'll likely merge the v3.0.x and v3.1.x versions of this PR, and they'll go into the snapshot tarballs, but we are not making a commitment to ever release v3.0.6 or v3.1.6. How do I know what MCA parameters are available for tuning MPI performance? The answer is, unfortunately, complicated. available. The sizes of the fragments in each of the three phases are tunable by following post on the Open MPI User's list: In this case, the user noted that the default configuration on his Please see this FAQ entry for more information (communicator, tag, etc.) shared memory.

Users wishing to performance tune the configurable options may synthetic MPI benchmarks, the never-return-behavior-to-the-OS behavior HCAs and switches in accordance with the priority of each Virtual Specifically, for each network endpoint, After the openib BTL is removed, support for Please note that the same issue can occur when any two physically Bad Things during the boot procedure sets the default limit back down to a low If we use "--without-verbs", do we ensure data transfer go through Infiniband (but not Ethernet)? This suggests to me this is not an error so much as the openib BTL component complaining that it was unable to initialize devices. therefore reachability cannot be computed properly. reported: This is caused by an error in older versions of the OpenIB user Each instance of the openib BTL module in an MPI process (i.e., send/receive semantics (instead of RDMA small message RDMA was added in the v1.1 series).
