A popular suite of open
source compilers for C (gcc), C++ (g++), and Fortran (gfortran).
module load gcc/4.1.2
GCC 4.1.2 is bundled with the SLES 10 SP1 operating system installation. For computationally-intensive work, however, we strongly recommend evaluating applications against the commercial-grade PGI and Sun Studio compiler suites to determine if either of them will deliver better performance. In practice there are substantial variations in performance, features, and compatibility among compilers, so some experimentation is in order.
