NOTE: The above compilers support automatic parallelization.

In addition, there are

• Java, (java, javac)
• GNU - The GNU Compiler Collection: (Version: egcs-1.1.1.)
  g77 - Fortran 77 compiler
  gcc - C compiler
  g++ - C++ compiler
  Documentation for these compilers can be found on the info pages. Type info in the shell, or give Emacs the command C-h i.
• G95 - Open source Fortran 95 compiler from g95.org
  Install by issuing this command somewhere in your $PATH:
  

     ln -s /home/parallab/plab/avle/aix/g95-install/bin/powerpc-ibm-aix5.1.0.0-g95 g95
  

  g95 - Compile with this command, use the same optimization options as for gcc.

We also have the following languages installed.

• Python 2.1 with Numeric Python.
  • www.python.org
  • Numeric Python: Efficient multidimensional arrays for Python.
  • Instant Python: Learn Python in a few minutes.
• Perl version 5.6.0 (built for AIX)
