Asking community for help regarding ISSM on Apple Silicon

justinquinn

Hello all,
For those of you running ISSM on Apple Silicon based machines under MATLAB, we would like to ask for your help debugging an issue we are having with our nightly runs. Assuming the above, could you please perform the following,

Install the shell2junit external package using the install.sh script
Load MATLAB with ISSM
cd to $ISSM_DIR/test/NightlyRun
Run, runme('id',430)

What we're checking for is if all of the tests pass with a SUCCESS message. If so, could you please provide the following information,

Are you using Xcode or the Command-Line Tools? Which version?
Which distribution of GFortran are you using (e.g. fxcoudert's port on GitHub, Homebrew, MacPorts)?
Which version of GFortran are you using?
Which version of MATLAB are you using?
The list of ISSM external packages that you installed, and which install scripts you used.
Your ISSM configuration.

We very much appreciate you time and the contribution you will be making to keeping ISSM stable on Apple Silicon-based machines.

Hi Justin, I ran the test as described and the output is below:

----------------finished:430-----------------------

I am using:
Xcode 14.3.1 Build version 14E300c
GNU Fortran (Homebrew GCC 13.1.0) 13.1.0
Matlab R2022b
with external packages:
autotools (./install-mac.sh), cmake (./install.sh), and PETSC (a modified version of install-3.17-mac-m1.sh to install 3.18.4)

Sorry I am not quite sure what is meant by ISSM configuration. Thanks for your efforts to make ISSM work nicely on M1 Macs though!

adamjhepburn Thank you, Adam, for taking the time to do this! These errors are in line with what we are experiencing, so at least we have consistency. 🙂
