Rnuunig CosmoMC on a cluster

Post by R Purnalingam » April 16 2017

I am trying to run COSMOMC on a cluster
And my job_file is as follows

#!/bin/bash
#PBS -N 1.sh
#PBS -q mini
#PBS -l nodes=1:ppn=20
#PBS -j oe
cd PBS_O_WORKDIR
export I_MPI_FABRICS=shm:dapl
export I_MPI_MPD_TMPDIR=/scratch/purna
mpirun -machinefile $PBS_NODEFILE -n 20 ./cosmomc test_planck.ini

Iam getting the following error when i try to run my script file.

--------------------------------------------------------------------------
mpirun was unable to launch the specified application as it could not access
or execute an executable:

Executable: ./cosmomc
Node: hpc004

while attempting to start process rank 0.

Did you forget to run "make clean" and "make"? Unless you run "make" the executable is not created.

Also, if you are using Planck data (as it looks from your .ini file), don't forget to source the Planck likelihood, i.e. source plc-2.0/bin/clik_profile.sh and a bunch of other commands
