SCITAS supports Intel compilers and Intel MPI (full proprietary) or GCC compilers and MVAPICH2 (full free). Other combinations are not supported.

Why do some system tools stop working after the intel module is loaded?

The Intel compiler includes their own versions of many libraries (and these must take precedence over the system ones). Sometimes these libraries do not include symbols which are needed by some system tools and these will no longer work. Examples of these could be: gitrsync, etc.

If a module exists providing the same tool one can just load that module.

If no module exists you will have to module unload intel before using the command and module load intel afterwards (any modules which depend on intel will simply become inactive and will be restored automatically).
