[issm-support] ISSM Questions

[Morlighem, Mathieu (334H-Affiliate)]

Hi Gordan,

thank you for your interest in ISSM. Matlab is only an interface for pre and post processing and is not required to do the actual simulation. The strategy that we generally use is to install ISSM on both a local machine (for pre-post processing with matlab) and on the cluster (where only issm.exe is compiled, i.e. with the option --with-modules=no). The matlab interface can then "ship" the binary input file to the cluster and fetch the output file once the run is completed (http://issm.jpl.nasa.gov/documentation/parallel/)

For your second questions, the PDD module is still under developments. We would be happy to help you implement dynamical surface and basal processes (would be in C++, not in matlab).

Thanks
Mathieu

Hello,

I have been working with the ISSM code, and I have a few questions:

1) Is there any way to make use of the computational resources
of a cluster that does not have MATLAB installed?

2) What is the recommended coding approach for incorporating
dynamical surface and basal boundary conditions?  There seem,
for example, to be some C++ routines relating to PDD schemes, but no
way to access them from the MATLAB front-end.

Thanks in advance,
