Programming Language Compilers

The following Sun compilers are provided on ISS Cent1 Interactive Unix Service:

• Fortran 90 - type: man f90 (on IUS) for more info.
• C - type: man cc for further info.
• C++ - type: man CC for further info.

The following compilers are supported on the HEC:

• Gnu Compilers - gcc = C Compiler, g++ = C++ Compiler, gfortran = Fortan 90 Compiler.
• Intel Compilers - icc = C Compiler, icpc = C++ Compiler, ifort = Fortran 90 Compiler.
• PGI Compilers - pgcc = C Compiler, pgCC = C++ Compiler, pgf90 = Fortran 90 Compiler.

The HEC also supports the following parallel programming paradigms:

• OpenMP - OpenMP is a set of compiler directives, library routines and environment variables that can be used to specify shared-memory parallelism in C, C++ and Fortran codes.
• MPI - Multi-node parallel jobs are typically written using MPI, a C/C++ and Fortran based Application Programming Interface that implements job parallelism via passing (network) messages between co-ordinated processes.
