Software

ARC provides user guides for the following software packages:

  • Unix: A detailed guide to the Unix operating system
  • OpenMP: An introduction to OpenMP, a common means of obtaining parallelism on shared-memory systems
  • MPI: An introduction to Message Passing Interface (MPI), a standard for obtaining parallelism, particularly on distributed-memory systems.
  • MATLAB: An introduction to MATLAB numerical computing software with instructions for and examples of submitting jobs to Ithaca
  • NAMD: An introduction to NAMD molecular dynamics software, including information on running, scaling, and GPU acceleration

The table below describes the availability of select (but not all) software packages on ARC systems:
