General Frequently Asked Questions

• How do I compile on Frost? There are no compiler wrappers on Frost. For instructions on compiling your code on Frost, see the Frost compiling page.
• Where are the programming environment modules? Unlike our other systems, Frost does not use programming environment modules. To load a compiler, unload the compiler you are currently using, and load the compiler you want to use: intel for Intel, pgi for PGI, pathscale for Pathscale.
• Can I load multiple compilers at once? It is strongly discouraged. Though it is possible to load two or more compiler modules at the same time, loading modules sets up an environment specific to the compiler, which may be changed by further compiler loads. It is highly recommended to either unload the compiler you are using, or use module swap oldcompiler newcompiler
