是否可以使用 gfortran 和 openmpi 在 Linux 中编译 NASA Parallel Benchmarks (NPB) 文件？

Question

I am attempting to run NPB benchmarking on my RHEL7.3 install but come into a similar issue as the question asked here

Error while building NAS benchmarks

Trying to make the BT benchmark, which is in fortran, I get the following error:

cd BT; make NPROCS=16 CLASS=W SUBTYPE= VERSION=
make[1]: Entering directory '/mnt/npb_install/NPB3.3-MPI/BT'
make[2]: Entering directory '/mnt/npb_install/NPB3.3-MPI/sys'

However I am not using Intel MPI but rather OpenMPI, though I don't full understand the implication of that.

My make.def file has the following mpi related settings

#-------------------------------------
# This is the fortran compiler usedd for MPI programs
#-----------------------------------------
MPIF77 = gfortran
# This links MPI fortran programs; usually the same as ${MPIF77}
FLINK = ${MPIF77}

#------------------------------------------
# These macros are passed to the linker to help link with MPI correctly
#-------------------------------------------
FMPI_LIB = -L/usr/lib/openmpi/lib/ -lmpi

#-----------------------------------------
# These macros are passed to the compiler to help find 'mpif.h'
#------------------------------------------
FMPI_INC = -I/usr/include/openmpi-x86_64/

Similar to those posted in the above question.

From the error, I assume that the input parameters -lmpi is not a valid input parameter for gfortran when compiling but removing it leads to a screen full of undefined references like:

 file.f:(.text+0x123): undefined reference to 'mpi_whatever_'

Is it possible to compile NPB with gfortran? Or am I clearly doing something wrong here? I have seen that using ifort is another option but I thought I'd ask the question before moving towards that possible solution

Answer 1

After hacking at it I resolved the issue with the following fixes, not sure what did it.

OpenMPI may have not been installed properly (was unable to call mpicc or other wrappers/comps), to fix it I ran the following commands

module avail
#displayed the openmpi-x86_64 module
module add open-x86_64
which mpirun
#displayed location of mpirun

The more likely fix was simply changing gfortran in the make.def file to mpif77
