[scb0115:mpi_rank_0][MPIDI_CH3_Init]

Please set LD_PRELOAD to the full path of libmpi.so of your MVAPICH2-GDR installation to avoid unexpected errors for GPU-based transfers

E.g. LD_PRELOAD=<PATH_TO_MVAPICH2_GDR_INSTALL>/lib64/libmpi.so

WARNING: Error in initializing MVAPICH2 ptmalloc library.Continuing without InfiniBand registration cache support.
