We've collected some references to the basic utilities that might be helpful in using Unity, as well as more in-depth references to concepts that might guide your growth in using Unity and other HPC resources. Please let us know if you find other helpful references so that we can include them here for others to use.

See also our annotated bibliography of HPC-related references.

Basic use


In contrast to Mac and Windows, many things are easier to do in Linux on the command line. Googling produces links to general references and tutorials or varying quality (over time you may find certain sites more reliable than others--for example, answers at Stack Overflow are generally of high quality because of extensive user review). Once at the Linux command line, you can search for help on a specific command using the man command. Here are some favorites.

Text editing

Unity offers three text editors, vim, emacs, and nano at the command line.

vim resources


SchedMD's official Slurm documentation, which includes man pages for user commands, as well as a Rosetta stone to facilitate translation between resource managers. 

Exit codes

They may be obtuse and cryptic, but exit codes, as reported in the email you get from a completed job, may help you diagnose a problem.

Handy tools


  • Software Carpentry's material on Make.
  • The Wikipedia page on Make includes a sketch of its long history.
  • Some projects use CMake.



NVIDIA's CUDA training.

Other computing resources


Unity's configuration closely resembles the Ohio Supercomputer Center's, facilitating interchange of programs and data. Much of OSC's introductory documentation is applicable to both environments, especially the HOWTOs.


Advanced Cyberinfrastructure Coordination Ecosystem: Services & Support (ACCESS), an advanced computing and data resource supported by the National Science Foundation.


Open Science Grid (OSG), a high-throughput computing consortium, also supported by the National Science Foundation.



Ask.Cyberinfrastructure is a developing question-and-answer format environment, similar to the Stack Overflow concept, for everyone involved with HPC, from researchers to system administrators.

HPC Carpentry

Software Carpentry has spawned HPC material.

Supercomputing in Plain English

The Oklahoma University Center for Education & Research regularly runs a series of webinars called Supercomputing in Plain English. Links to slide sets and YouTube videos of the most recent webinars are on that site.


The Texas Advanced Computing Center publishes free HPC textbooks by Victor Eijkhout; other free textbooks on parallel programming and C++ and Fortran are on that site.

Sterling et al.

The most comprehensive printed reference is the textbook High Performance Computing--Modern Systems and Practices by Thomas Sterling, et al., Morgan Kaufmann 2018.
