| The GNU compiler collection (GCC) is accessible in the cluster trough its commands and usual options. By default the compilers installed are from the GCC 4.7.2 version. ((In this version there is a optimization option (''march'') to generate code specifically for the cluster's nodes architecture (Opteron 6200 series, 15th Family //Bulldozer// Interlagos). This compilation option doesn't guarantee that the mathematical standard defined in GCC is followed, so its use is not recommended unless you know what you're doing. | The GNU compiler collection (GCC) is accessible in the cluster trough its commands and usual options.

| * ''-O'' Generate optimized code to get better performance. Is equivalent to ''-O1''. Alternatively, you can use the options ''-O0'', ''-O2'' or ''-O3''. Number indicates the optimization level, being 0 the less optimization and 3 the most (( 3 is quite aggressive and can lead to issues). | * ''-O'' Generate optimized code to get better performance.
