Mpi_Problem

Sherif_Yehia — Tue, 16 Aug 2022 15:35:09 GMT

Dear Expert

I am trying to set Elpa software with Intel compiler mpiifort

got the following errors.

checking whether mpiifort accepts -g... yes
checking for function MPI_INIT... no
checking for function MPI_INIT in -lmpichf90... no
checking for function MPI_INIT in -lfmpi... no
checking for function MPI_INIT in -lfmpich... no
configure: error: Could not compile an MPI Fortran program

Could you help me to figure out my mistakes

Thanks for your effort and time

I think you'd get a more informed response in Intel® oneAPI HPC Toolkit - Intel Communities , but my guess is that you don't have an MPI library installed that mpifort knows how to find.

I agree with Steve - looks like either you don't have an Intel compiler compatible MPI installed or you didn't run the setvars script to path MPI correctly. Below is where you can download Intel MPI, from here.

then go to THIS PAGE and click the "Documentation" tab and read the "Get Started" for your OS

Hello Steve & Ron

Thanks my dear experts for the quick advice I already have the . bashrc

I downloaded and set up the l_mpi_oneapi_p_2021.6.0.602_offline.sh

Please see the .bashrc

# .bashrc

# Source global definitions
if [ -f /etc/bashrc ]; then
. /etc/bashrc
fi

# User specific environment
if ! [[ "$PATH" =~ "$HOME/.local/bin:$HOME/bin:" ]]
then
PATH="$HOME/.local/bin:$HOME/bin:$PATH"
fi
export PATH

# Uncomment the following line if you don't like systemctl's auto-paging feature:
# export SYSTEMD_PAGER=

# User specific aliases and functions

/opt/intel/oneapi

# FC=ifort

source /opt/intel/oneapi/setvars.sh intel64
source /opt/intel/oneapi/mpi/2021.6.0/env/vars.sh

# CC=icc

source /opt/intel/oneapi/setvars.sh intel64

source /usr/share/Modules/init/sh

export F77=ifort
export FC=ifort
export F90=ifort
export FFLAGS='-O3 -xhost -g'
export FFLAGS_NOOPT='-O0 -g'
export CC=icc
export CXX=icpc
export PATH=$PATH:/opt/intel/oneapi/compiler/2022.0.2/linux/bin/intel64:/opt/intel_openmpi/bin
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/intel_openmpi/lib:opt/intel/oneapi/compiler/2022.0.2/linux/compiler/lib/intel64_lin
export LD_RUN_PATH=$LD_RUN_PATH:/opt/intel_openmpi/lib

Possibly I am doing another stupid mistake

I hope you can direct me

Have a wonderful time

shoot, I should have told you to set FC=mpiifort, not ifort

before running ./configure, confirm the env var is set

echo $FC

should return

mpiifort

which mpiifort

to confirm your setvars.sh was invoked. Also, you do not need to source /opt/intel/oneapi/mpi/2021.6.0/env/vars.sh, setvars does that.

next, try

./configure FC=mpiifort

along with any other config options you pass to it.

Thanks very much for your quick response

I guess I found my problem with google help & your advice in

1-.bashrc file

2-https://stackoverflow.com/questions/70687930/intel-oneapi-2022-libimf-so-no-such-file-or-directory-during-openmpi-compila

Please acknowledge that or direct me { I am beginner}

I created intel_libs.conf in ld.so.conf.d

with the line in intel_libs.conf
/opt/intel/oneapi/compiler/2022.1.0/linux/compiler/lib/intel64_lin

then try ldconfig

It work thanks again

Thanks v. much

Best regards

Ron_Green — Thu, 18 Aug 2022 14:03:28 GMT

you did in 'source /opt/intel/oneapi/setvars.sh' ?

maybe your configure needs you to tell it where MPI is located?

./configure --help

or look in the configure script for any MPI* variables it may be using. better yet, attach your configure script here
