<div dir="ltr">Hi Pratik,<div><br></div><div>I haven't built FLASH for Perlmutter, but a few tips from building other codes on Perlmutter and FLASH on other machines.</div><div>1. Choose your programming environment to work in first. E.g. "PrgEnv-GNU" is a good choice to get things working quickly. See <a href="https://docs.nersc.gov/systems/perlmutter/software/#compilers">https://docs.nersc.gov/systems/perlmutter/software/#compilers</a></div><div>2. Use the compiler wrappers. See <a href="https://docs.nersc.gov/development/compilers/wrappers/">https://docs.nersc.gov/development/compilers/wrappers/</a></div><div>3. Consider using OpenMPI for your first pass at compiling FLASH, as I find it easy to compile FLASH with OpenMPI. See See <a href="https://docs.nersc.gov/development/programming-models/mpi/openmpi/">https://docs.nersc.gov/development/programming-models/mpi/openmpi/</a></div><div>4. Use built-in HDF5 (either serial or parallel is available depending on what you need for that particular build of FLASH.) See See <a href="https://docs.nersc.gov/development/libraries/hdf5/">https://docs.nersc.gov/development/libraries/hdf5/</a> </div><div><br></div><div>Good luck!</div><div><br></div><div>Scott</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, Feb 13, 2024 at 3:59 PM Pratik Manwani <<a href="mailto:pkmanwani@gmail.com">pkmanwani@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">Hello all,<br>

Has anyone compiled FLASH on NERSC Perlmutter?<br>
<br>
There are makefiles for different site configurations on Nersc but I<br>
could not find one for Perlmutter. Let me know if possible, Thanks for<br>
the help!<br>
<br>
Best,<br>
Pratik<br>
