Trilinos

Using Trilinos on Hopper

The Trilinos module is dependent on Cray's installation of PETSc, so you must make certain this modulefile is loaded before using Trilinos.

Caveat: The trilinos module is not supported with use of pgi versions 11.x.x. This is due to an incompatibility in c++ code built with previous versions of PGI.  So when using PGI compilers, please swap to pgi/10.9.0 first. 

Then to use the Trilinos packages, load its module:

module load trilinos

After you load the Trilinos module, all header and library locations are set automatically and you are ready to compile your code. No Trilinos-specific linking information is required on the command line. This should be true for all compiler environments available on Hopper, provided, of course, that you use the Cray compiler wrappers (ftn, cc, and CC). If you link to more than one Trilinos package, the libraries should be linked automatically in the correct order of package dependency.  See the documentation (below) for more information on this.

Documentation

On the Cray systems, after you have loaded the Trilinos modulefile, you can use man trilinos to get some basic information.  More info is available in Cray's Programming Environment User's Guide.  The base document number for this is S–2396.  Cray documents are generally of the form S-xxxx-nn, where nn relates to the release.  The June, 2010 release of the Programming Environment User's Guide is S–2396–50.
