Notes for NCI (Gadi)

November 2019

Quickstart

# Instructions for Gadi

#
# Load module for netcdf
#
module load intel-compiler/2019.3.199
module load netcdf/4.7.1

#
# Clone the git repository
#
git clone https://github.com/jpevans/BTrIMS.git
cd BTrIMS

#
# Compile with OpenMP
#
# gfortran equivalent:
# gfortran -ffree-line-length-512 -fopenmp -O3 -c BTrIMS.f90
ifort -03 -fopenmp -c BTrIMS.f90

#
# Link the executable
#
# gfortran equivalent
# gfortran -fopenmp -O3 -L/apps/netcdf/4.7.1/lib -lnetcdff BTrIMS.o -o main
ifort -O3 -fopenmp -L/apps/netcdf/4.7.1/lib -lnetcdff BTrIMS.o -o main

#
# Run BTrIMS from 11 Jan 1980 to 13 Jan 1980, storing the results in subdirectory ./outputs
#
chmod u+x main
mkdir outputs

#
# PBS jobscript for Gadi
#
cat - <<EOF >191119-btrims.sh
#!/bin/bash
#PBS -q normal
#PBS -l walltime=10:00:00
#PBS -l ncpus=48
#PBS -l mem=64GB
#PBS -l storage=gdata/hh5 
cd $PBS_O_WORKDIR
ulimit -s unlimited
./main 11 01 1980 13 01 1980 ./outputs

EOF

#
# Submit the job to Gadi normal queue
#
qsub 191119-btrims.sh

#
# Example resource usage via qstat
#
Every 60.0s: qstat -f 149802                                     gadi-login-04.gadi.nci.org.au: Wed Nov 20 10:19:04 2019

** Required: a brief introduction to what is the format and contents of these files

Verify that scaling with OpenMP gives consistent output

Visualise with Panoply

First, download and install Java

Then download and extract Panoply
