README.md

Purpose:

Example of using NetCDF libraries on the cluster. The specific example creates a random vector and writes it to a netCDF (nc) file.

Contents:

(1) netcdf_test.f90: Fortran 90 source file

(2) Makefile: Makefile to compile the source code

(3) netcdf_test.sbtach: Btach-job submission script to send the job to the queue

Example Usage:

source new-modules.sh
module load gcc/4.8.2-fasrc01
module load openmpi/1.10.0-fasrc01
module load netcdf/4.1.3-fasrc03
make
sbatch netcdf_test.sbatch

Example Output:

[pkrastev@sa01 NETCDF]$ ncdump vector_x.nc
netcdf vector_x {
dimensions:
	x = 100 ;
variables:
	double data(x) ;
