Issue

Why is there such error "libibverbs: Warning: RLIMIT_MEMLOCK is 32768 bytes." when running mvapich2 jobs? The full error messages are:

[user1@hpc ~]$ /usr/lib64/mvapich2/1.4-gcc/bin/mpirun -n 1 ./cpi

libibverbs: Warning: RLIMIT_MEMLOCK is 32768 bytes.
    This will severely limit memory registrations.
