Description from McStas website: “McStas is a general tool for simulating neutron scattering instruments and experiments. It is actively supported by DTU Physics, NBI KU, ESS, PSI and ILL.”
Using mcstas:
McStas is run on the command line using a job submission script eg:
#!/bin/bash
#SBATCH -n 4 #### Number of cores to use
#SBATCH -o %j.o
#SBATCH -e %j.e
# Run for 60 hours
#SBATCH -t 60:00:00
#SBATCH --exclusive
#Load desired
module load mcstas/2.4.1-intel-17.0.2
# compiling the c file
mcstas -I <path_to_instrument_files> -t -o <c_file> <instr_file>
# compiling using mpicc
mpicc -o <outputfile> <c_file> -lm -DUSE_MPI
# running
mcrun <outputfile> --ncount=<neutrons> --format=PGPLOT --mpi=auto
wait
Submit using:
[me@scarf]$ sbath jcl
Where jcl is the name of the job submission script file from above. To change the number of cores, please make sure to change the #SBATCH -n value.
To monitor your jobs progress use the normal LSF batch commands eg:
[me@scarf]$ squeue -u <username>
or
[me@scarf]$ squeue -u <username> -l
ISIS_tables have been added to McStas.
