On Discoverer, there two known issues related to Intel components:
-Intel MPI for input and output does not seem to work (none of the MPI data representation work).
-Intel COMPILER (both IFX and IFORT) creates problematic executables.
The code seems to work fine only if the grid points/node ratio is kept relatively low.
On small number of nodes (1-4), the code crashes with segmentation fault.
The fault depends on the grid points/node ratio and is not a clear point on the code.
Possible reasons:
-Arrays pre-allocated (e.g. in. theta_check and helmoltz).
On the same machine, if the code is compiled with Nvidia, AMD or Gfortran no problems arise.
