In addition to the software you'll normally find in /usr/local, these packages were compiled specifically to work on the cluster.

Compilers:

• GNU - gcc, gfortran
• Intel Cluster Studio - icc, icpc, ifort
• Portland Group - pgcc, pgCC, pgc++, pgfortran
• NAG - nagfor

Debuggers:

• GDB
• Intel
• PGI
• TotalView

MPI Libraries:

• mvapich
• mvapich2
• openmpi

NetCDF:

NetCDF is compiled against each of the available compilers.
Note that when you load the module for your compiler, the NetCDF libraries are also loaded.

Modules:

Modules are used to quickly and easily setup your computing environment.
Loading a module will correctly set up the paths to your binaries and libraries so you don't have to do it manually.
To use modules, you only need a few simple commands or use "module help" to see all options:

• module avail - see what environments are available
• module load - load your environment
• module list - see what you have loaded
• module purge - remove all modules

Software?

Are we missing software that you need to do your work?
If so, send an email to help@ucar.edu and we can discuss its installation on the cluster.
