The binary topo_bathy file cannot be read on aarch64 machine #835

Closed mnagaso closed 3 months ago

Hello,

I am trying to run the code on my aarch/arm64 (linux on M1 mac actually) machine, and found that an error below happens when I run xmeshfem3D.

mpirun -n 1 ./bin/xmeshfem3D 

Program received signal SIGSEGV: Segmentation fault - invalid memory reference.

So would it be possible to provide the data itself for arm64 or script to create this bin ?

Thank you very much for your help,

This problem has been resolved after recreating the topo_bathy_file by running the script, ./run_create_topo_bathy_file.py etopo4

A few update of this script was necessary for the recent versions of GMT and Numpy (https://github.com/SPECFEM/specfem3d_globe/pull/836)
