GNU Compilers

Fortran, C and C++ compilers produced by the GNU Project. 

Availability and Restrictions

Versions

The following versions of the GNU compilers are available on OSC systems:

CCAPP Condo on Ruby Cluster

Condo model refers to that the participants (condo owners) purchase one or more compute nodes for the shared cluster while OSC provides all infrastructure, as well as maintenance and services. CCAPP Condo on Ruby cluster is owned by the Center for Cosmology and AstroParticle Physics, at OSU. Prof. Annika Peter has been heavily involved in specifying requirements.

Hardware

Detailed system specifications:

  • 21 total nodes

    • 20 cores per node

Prof. Gaitonde's Condo on Ruby Cluster

Condo model refers to that the participants (condo owners) purchase one or more compute nodes for the shared cluster while OSC provides the infrastructure, as well as maintenance and services. Prof. Gaitonde's Condo on Ruby cluster is owned by Prof. Datta Gaitonde from Mechanical and Aerospace Engineering Department of Ohio State University.

Hardware

Detailed system specifications:

  • 96 total nodes

    • 20 cores per node

Parallel netCDF

PnetCDF is a library providing high-performance parallel I/O while still maintaining file-format compatibility with  Unidata's NetCDF, specifically the formats of CDF-1 and CDF-2. Although NetCDF supports parallel I/O starting from version 4, the files must be in HDF5 format. PnetCDF is currently the only choice for carrying out parallel I/O on files that are in classic formats (CDF-1 and 2). In addition, PnetCDF supports the CDF-5 file format, an extension of CDF-2, that supports more data types and allows users to define large dimensions, attributes, and variables (>2B elements).

Batch Requests

Batch requests are handled by the TORQUE resource manager and Moab Scheduler as on the Oakley and Glenn systems. Use the qsub command to submit a batch request, qstat to view the status of your requests, and qdel to delete unwanted requests. For more information, see the manual pages for each command.

There are some changes for Ruby, they are listed here:
