attempting to break the get into multiple rdma fragments A little background. Historically ob1 always registered the entire memory region when the RGET protocol was in use. This changed when Mellanox added support to fragment RGET using the btl_prepare_dst function. Now that the BTL layer has changed to split out the limits of get/put there is explicit fragmentation code in ob1. Before this commit the registration was still done per RGET fragment. This commit will attempt to register the entire region before creating RGET fragments. If the registration is successfull then all RGET fragments will use this registration otherwise they will each attempt to register their own segment of the receive buffer. If that fails enough times each fragment will give up and fall back on send/recv. |
