Hi Openfabrics, A question or bug probably, after upgrading to new OFED with libibverbs-1.1 release. I experienced problems with running Fluent CFD application with HP-MPI 2.2.5.1 as i saw the libibverbs initialization failed due to library throws an error saying maximum pinnable memory i.e memlock insufficient.
"ibv_create_qp failed" "Unable to Initialize RDMA device". I didn't have this problem in earlier versions. I fixed this by changing the hardlimit/softlimit to more than 32k which was default on my system. But i am thinking why does the RDMA initialization fails if it's 32k which didn't happen for libibverbs version 1.0.4. It should throw a warning according to the check_memlock function in the libibverbs source directory. But that's not happening in turn the ibv_create_qp is failing, is it not better to set the rlimit by the library itself using setrlimit(). This looks to be a change with the ConnectX IB 4th Gen Infiniband hardware in place that libibverbs is requesting memlock to be more than 32k.
