MPICH was compiled with the Infiniband libraries. Hence, these need to be linked in. An easy way to find which libraries need to be include is by doing a mpif90 -show for example.

My environment variables:

USE_MPI=y
USE_MPIF=y
USE_MPIF4=y

MPI_LOC=/usr/local
MPI_LIB=/usr/local/lib
MPI_INCLUDE=/usr/local/include

LIBMPI=-lmpich -lopa -lmpl -lrt -lpthread

Compilation leads to undefined references:



/usr/local/lib/libmpich.a(rdma_iba_init.o): In function `MPIDI_CH3I_CM_Finalize':
rdma_iba_init.c:(.text+0x185): undefined reference to `ibv_dereg_mr'

Thanks for your help.
