Software on Yellowstone

Environment overview | Software packages

The Yellowstone system and the Geyser and Caldera analysis and visualization clusters have nearly all software in common. Notable exceptions are GPU-related packages that are provided for the Geyser and Caldera systems.

Because of the similarities between systems, your non-GPU codes will run on any of them. Which system to use depends largely on the needs of your project.

As you will see below, CISL provides an array of open-source and commercial third-party products that you can load as needed for programming, compiling, computing, analysis, and file management tasks.

Environment overview

The following are common to the HPC, analysis, and visualization clusters' system software:

Operating system: Red Hat Enterprise Linux.

Scheduler: Platform LSF (load sharing facility) is used to schedule jobs.

Shells: Four shells are supported on login and compute nodes: tcsh, csh, bash, and ksh. The default is tcsh.

Compilers: Intel, PathScale, PGI, GNU, and NVIDIA compilers are provided. CUDA and OpenCL are available for developing GPGPU codes for the Geyser and Caldera clusters.

Environment modules

Our Consulting Services Group (CSG) provides an extensive set of environment modules to help you manage the many environment variables, compilers, libraries, and other software. With the variety of compilers in particular, using the environment modules is especially important to ensuring that your programs work as intended.

You can use some modules regardless of which compiler is loaded, while others are compiler-dependent.

See the following pages for searchable lists of software packages and descriptions that are drawn from their module help files:
