Intel

bwUniCluster currently provides Intel compiler suite versions:

• 13.1 (default)
• 12.1

To load the default compiler suite execute in your terminal session:

$ module load compiler/intel

To load your prefered version, e.g. 12.1, enter:

$ module load compiler/intel/12.1

For details about unloading or switching compiler suites, please see chapter environment modules.

Default Intel compiler suite - version 13.1

This module provides the Intel® compiler suite version 13.1.3 via commands 'icc', 'icpc' and 'ifort', the debugger 'idb' as well as the Intel® Threading Building Blocks TBB and the Integrated Performance Primitives IPP libraries (for details see also http://software.intel.com/en-us/intel-compilers/).

The related Math Kernel Library MKL module is 'numlib/mkl/11.0.5'. The related Intel MPI module is 'mpi/impi/4.1.1-intel-13.1'. The Intel icpc should work well with GNU compiler 4.7.

The compiler suite contains:

  icc           # Intel® C compiler
  icpc         # Intel® C++ compiler
  ifort         # Intel® Fortran compiler
  idb          # Intel® debugger in GUI mode
  idbc         # Intel® debugger in console mode

For local documentation consult the module help:

$ module help compiler/intel/13.1

or the man pages of each compiler:

$ man icc
$ man icpc
$ man ifort

• Intel® Fortran Composer XE Version 2013
• Intel® C++ Composer XE Version 2013

For some Intel® compiler option examples, hints on how to compile 32bit code and solutions for less common problems see the tips and troubleshooting doc under:

  $INTEL_DOC_DIR/intel-compiler-tips-and-troubleshooting.txt

For details on library and include directories of this compiler suite please enter:

$ module show compiler/intel/13.1

Note that, the environment variables and commands are only available after loading this module.

GCC

bwUniCluster currently provides GNU compiler suite versions:

• 4.5
• 4.7 (default)
• 4.8

To load the default compiler suite execute in your terminal session:

$ module load compiler/gnu

To load your prefered version, e.g. 4.5, enter:

$ module load compiler/gnu/4.5

For details about unload or switching compiler suites, please see chapter environment modules.

Default GNU compiler suite - version 4.7

This module provides the GNU compiler suite version 4.7.3 via commands 'gcc', 'g++' and 'gfortran' (see also 'http://gcc.gnu.org/'). The GNU compiler has been build with gmp-4.3.2, mpfr-2.4.2 and mpc-0.8.1.

The compiler suite contains:

  cpp        # GNU pre processor
  gcc         # GNU C compiler
  g++       # GNU C++ compiler
  gfortran  # GNU Fortran compiler (Fortran 77, 90 and 95)

Libraries can be found under:

  $GNU_LIB_DIR = /opt/bwhpc/common/compiler/gnu/4.7.3/x86_64/lib64

For local documentation consult the module help:

$ module help compiler/gnu/4.7

or the man pages of each compiler:

$ man cpp
$ man gcc
$ man g++
$ man gfortran

For further online documentation visit:

• http://gcc.gnu.org/onlinedocs/

For details on library and include directories of this compiler suite please enter:

$ module show compiler/gnu/4.7

Please do not add the gnu compiler module to any automatic environment setup procedure (neither to ~/.profile nor to ~/.bashrc).
Please note, that the environment variables and commands are only available after loading this module.
