Perl and UNIX-shell scripting

Automating and simplifying tasks with command-scripts is a routine procedure in the Unix/Linux environment. We regularly help users develop scripts to suit their specific needs.

Code Development

We provide assistance with code compilation and debugging in serial and parallel environments.

Computational Physics

Computational physics methods are sometimes useful and applicable to problems in other fields. We provide some consultation for computational physics algorithm selection and implementation.


From the installation of programs and data (e.g., genetic databases), to helping users get started, bioinformatics support is a key support area.

General Usage

GACRC staff are available to provide consultation in order to facilitate and optimize the use of GACRC’s resources. We are available to meet with small groups of users, and to provide guest lectures for courses that use GACRC resources.
