Packaged Binaries

You can install applications on our HPC using Spack: a Linux package manager that makes installing scientific software easy. With Spack, you can build a package with multiple versions, configurations, platforms, and compilers, and all of these builds can coexist on the same machine.

• To list all available packages:

  • spack find

• To load a package into your environment:

  • spack load

  • You can specify a software version as part of the load:

  • spack load python@3.7.3 loads Python 3.7.3

Python and PIP

If you load install Python using Spack (above) you can use PIP to install other modules:

• spack load python

• python3 -mpip install matplotlib

...

If you need an application that’s not available through Spack please contact the Helpdesk: helpdesk@floridapoly.edu or 863.874.8888.
