Many popular software packages are installed and available as modules. There may be several versions of a package available.
Software packages are available as modules and are accessible from the compute nodes of any of our three clusters. They are not available on the login nodes so you will need to be in an interactive session to access them. A list of installed software can be seen by clicking the link below, but may not be as current as using the
To see, access, and get information on individual software packages available on the system, use the module commands detailed below. If you have trouble accessing the module command, see our FAQ section.
module load modulename
module unload modulename
Example for Using Modules
First log in to the login node:
To display a list of the available packages:
To load the latest installed version of the "Trinity" software:
module load trinity
To list the software you currently have loaded:
To unload all modules if you want to start over. Logging out will also unload modules.

Using and Installing Python
Follow this link for more information on using Python.
There are several compilers available for your use. Remember when you run your code and you need to do a module load that you use the same version of compiler that the code was originally compiled with.
- GCC is available by default. gcc --version shows that it is 4.4.4 That version was installed at cluster installation and has not been updated to maintain consistency between compiling software and subsequently running it. If you also need the GNU Scientific Libraries (gsl), that is available using module load gsl which will get you version 1.15
- The Intel 2012 compiler suite is available as a module. module load intel will load the 2012 suite. It is the default for the same reason as gcc. The math kernel libraries (mkl) are provided when you module load intel (any version) - no separate step is required.
- The Intel 2013 compiler suite is also available as an optional module. module load intel/2013.5.192 will provide that version if needed.
- The latest Intel suite is now available with module load intel/xe.2016.u2. Unlike earlier versions, you do not need to separately load the MPI capable compiler. For detailed information, refer to the Intel documentation:
- intel-mpi/2012.0.032 is the default version which matches the non-mpi version. Use module load intel-mpi
- intel-mpi/2013.5.192 is available by specifying module load intel-mpi/2013.5.192
- openmpi version 1.4.4 is available by specifying module load openmpi
- mpich2 is available at version 1.4.1p1 by default or you can get version 3.1.4 wth module load mpich2/3.1.4
The new cluster has Intel V3 Haswell processors. A key feature of these is AVX2. Read this Intel document.
For AVX2 support, compile with the -xHOST option. Note that -xHOST alone does not enable aggressive optimization, so compilation with -O3 is also suggested. The -fast flag invokes -xHOST, but should be avoided since it also turns on interprocedural optimization (-ipo), which may cause problems in some instances.
For GNU compilers, AVX support is only available in version 4.6 or later. For AVX support, compile with -mavx
The principals are similar for ElGato except that the intel and intel-mpi compilers are only available for the 2013 versions.
openmpi is available both for version 1.6.5 and version 1.8.1
El Gato has a separate web site with easy to follow instructions.
Puma, Ocelote, and El Gato all run CentOS7 and have the following compilers available:
Common Software Packages
Installing additional software
To submit a request to have software installed on the UArizona HPC systems, use our HPC Software Install Request form. There is no expected time frame for how long it takes to install software, there are many variables that determine this. If you haven't heard back in a week, it is reasonable for you to follow up with a support ticket
You may also install software packages into the space that is allocated to you with your HPC account. However, you cannot install software that requires root permission or use a method like "yum install" that accesses system paths. For information on installing software locally, see our online guide for an example.
