The Research Computing Support Group (RCSG) manages shared computational clusters for a wide range of research projects affiliated with Rice University and the Texas Medical Center.
Please visit the RCSG Home Page for more information.
Because our clusters are highly complex environments, we do expect our users to acquire a basic set of skills before they get started. We understand that the range of computing experience among researchers can vary widely. In any cross-disciplinary field, there exists a need for introductory material to get researchers up to speed on fundamental concepts. We've gathered the following list of tutorials on varying computing subjects that we think will be of use.
At the least, a cluster user should understand:
- Basic file/directory manipulation under Linux
- Creating/Editing files under Linux
- Writing and submitting job scripts
- How to login to the clusters
- How to copy data in and out of the clusters
- Know whether you jobs are serial or parallel
All of the clusters that make up our shared computing resources run the Linux operating system. Using Linux is very similar to using Windows or MacOS on the desktop level, but that changes when it comes time to perform tasks remotely, as we do with the RCSG clusters. In order to work on RCSG clusters, users must use the command line interface (CLI).
In order to submit compute jobs to the clusters, a basic understanding of shell scripting is required. Job submission scripts typically use Bash, but can employ more advance scripting techniques as well.
Parallel Programming (MPI)
Parallel Programming (OpenMP)
Part of the mission of the RCSG is to serve as an onramp for our researchers to scale their problems up to the minimum size requirements at big national supercomputing resources. One such national resource is the Extreme Science and Engineering Discovery Environment or XSEDE
