C/C++ Commands associated with Compilers

Compiler	Serial * fileName extension, not command used, determines language version (can be changed by command flags)			Parallel * See the MPI doc.
	Commands	C++ fileName extensions	C fileName extensions	C++	C
Intel	icc, icpc (forces C++)	.C, .cc, .cpp, .cxx, .c++	.c	mpiCC	mpicc
GNU	gcc, g++, cc	.C, .cc, .cpp, .cxx, .c++	.c

Please note, to check which version of the aforementioned compilers is installed, issue at the command line the following command, for example for the Intel fortran:

ifort --version

use icc, gfortran, etc. for the other compilers.

Fortran 90/Fortran 77 Commands associated with Compilers

Compiler	Serial * fileName extension, not command used, determines language version (can be changed by command flags)			Parallel * See the MPI doc.
	Commands	Fortran 90 fileName extensions	Fixed Format fileName extensions	Fortran 90	Fortran 77
Intel	ifort	.f90 (.F90 preprocessed)	.f, .for, .ftn (.F, .FOR, .FTN, .FPP preprocessed)	mpif90	mpf77
GNU	gfortran	.f90 (.F90 preprocessed)	.f, .for, .ftn

Other Commands associated with Compilers

Compiler	Debugger	Linker	Profiler
Intel	idb^*	ld	gprof
GNU	gdb	ld	gprof, gcov

* Please note: It is not possible to run the Intel debugger from the login nodes, instead idb can be run within an interactive session obtained via qrsh (to invoke a qrsh session refer to: How to Get an Interactive Session through SGE).
