The Intel Compilers are available as modules for 32bit (depricated) and 64-bit version. To see the available versions of the Intel Compilers type

 module av ics

which currently shows

 -------------------- /cm/shared/uniol/modulefiles/COMPILER ---------------------
 ics/2013_sp1.3.174/32 ics/2013_sp1.3.174/64

To load the module of your choice type e.g.

 module load ics/2013_sp1.3.174/64

The commands for the available languages are

Name Description
icc C compiler
icpc C++ compiler
ifort Fortran compiler


Advantages

  • usually best performance for C and Fortran code on Intel processors
  • high performance with OpenMP
  • high optimization done by compiler
  • Fortran extension coarray implemented


Disadvantages

  • performance of C++ code can be moderate
  • relative slow compilation
  • not free, only for Intel architecture available
  • newest standards may missing
  • sometimes too enthusiastic/aggressive in optimization


Intel Cluster Studio addons

Within the Intel Cluster Studio several tools and libraries for debugging, profiling and analyzing of program code are included:

  • MKL (Math Kernel Library)
  • VTune
  • Intel Trace Analyzer
  • Intel Thread Checker
  • Intel Debugger (idb)
  • Thread Building Blocks
  • Intel(R) Advisor Command Line Tool
