[mpich-discuss] MPICH configure

[Zhou, Hui]

Hi Bruce,

Thanks for the details. Since you already instructed `sbatch` with `-N 2 -n 6` I thought you could simply run with `srun`, i.e. without further `-n`? I believe hydra also reads environment so you could also try `mpiexec` without `-n`. Did you also try `-N 1` and `-N 6`?

Hi Hui,

Sorry for the late reply, I keep getting pulled off on other projects. I’m actually running a test suite most of the time, so the job scripts look like


#!/bin/csh

#SBATCH -t 02:30:00

#SBATCH -A XGA

#SBATCH -p short,slurm,gpu

#SBATCH -N 2

#SBATCH -n 6

#SBATCH -o ./test.out

#SBATCH -e ./test.err



source /etc/profile.d/modules.csh



source ~/set_mpich

env | grep PATH

module list



#make check-ga MPIEXEC="mpirun -n 6 "

make check-ga MPIEXEC="srun -n 6 "



I’ve tried using mpirun, srun and mpiexec in the MPIEXEC variable. If I run a test standalone, then the job submission script is


#!/bin/csh
#SBATCH -t 02:30:00
#SBATCH -A XGA
#SBATCH -p short,slurm,gpu
#SBATCH -N 2
#SBATCH -n 6
#SBATCH -o ./test.out
#SBATCH -e ./test.err

source /etc/profile.d/modules.csh

source ~/set_mpich
env | grep PATH
module list

srun -n 6 test.x > test.out



Again, I’ve tried running with mpirun, srun, and mpiexec. The environment in the set_mpich file is



module purge

module load gcc/5.2.0

module load python/2.7.8

module load cmake/3.8.2

module load git

module load mkl

setenv CC gcc

setenv CFLAGS "-pthread"

setenv CXX g++

setenv CXXFLAGS "-pthread"

setenv FC gfortran

setenv FCFLAGS "-pthread"

unsetenv F90

unsetenv F90FLAGS



setenv PATH /people/d3g293/mpich/mpich-3.3.2/install/bin:${PATH}

setenv MANPATH /people/d3g293/mpich/mpich-3.3.2/install/share/man:${MANPATH}

setenv LD_LIBRARY_PATH /people/d3g293/mpich/mpich-3.3.2/install/lib:${LD_LIBRARY_PATH}
