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
