• make sure you have intel compilers on

• cd into the /work directory and run “make all”. This will automatically compile and link your program based on your runtime environment.

• You should get a adcprep, adcpost, dgswem, and dgswem_serial binary

Building on Frontera

Load the necessary modules:

module load TACC intel/23.1.0 impi

This loads the Intel compilers for Fortran and C: ifort and icx, as well as MPI. Then run make all as above.

Building on Vista

On the new machine Vista, we will instead use NVIDIA compilers. Here we can choose between the regular CPU version and a GPU-accelerated version (still in development). First, load the necessary modules by running

module load TACC

The Fortran compiler is now nvfortran and the C and C++ compilers nvc and nvc++.

CPU version

This is the default version. To compile, run

cd work
make compiler=nvhpc all

GPU version

This code is maintained in a separate branch gpu. Run

git fetch --all
git checkout gpu

to sync this branch. Then compile:

cd work
make all

Build a test case

Zach from the water institute has graciously lended us a program to build a test case, which we will adapt for DGSWEM:

...

Congrats! You have just run your first test case of dgswem!
