We support PGI, GNU, Intel, and Cray compilers. These should be more than sufficient; it is unlikely that we will add other compilers such as Borland. More information on compiling can be found at Compiling and see Modules for assistance with modifying your environment and changing compilers. When compiling code for the compute nodes, do not use the compilers directly, instead use the Cray wrappers (cc, CC, ftn).
We are investigating some new profiling features for standard MPI programs and are unlikely to purchase other compilers unless there is a strong demand for them. Please let us know if you would like to request a compiler (or any other software) by sending us an email at help@xsede.org
