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

Introduction

Twenty of the new Ruby nodes have an Intel Xeon Phi coprocessor.  Some of the older debug nodes do also.  This guide explains how to build and run code for the Phi on Ruby.  It does not discuss programming techniques or performance issues.

For background information on the Xeon Phi and techniques for using the Phi efficiently, the following references may be useful: 

CDO

Oakley

CDO (Climate Data Operators) is a collection of command line operator to manipulate and analyse climate and NWP model data. It is open source and released under the terms of the GNU General Public License v2 (GPL).

Versions

CDO is available on Oakley Cluster. The versions currently available at OSC are:

NCL

Glenn, Oakley

NCL (The NCAR Command Language), is a free interpreted language designed specifically for scientific data processing and visualization. It is a product of the Computational & Information Systems Laboratory at the National Center for Atmospheric Research (NCAR) and sponsored by the National Science Foundation.

Projects who would like to use the Ruby cluster will need to request access.  This is because of the peticulars of the Ruby envionment, which includes its size, MICs, GPUs, and scheduling policies.  

Ruby

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.

In October, 2004, OSC engineers installed three SGI Altix 350s. The Altix 350s featured 16-processors each for SMP and large-memory applications configured. They included 32GB of memory, 161.4 Gigahertz Intel Itanium2 processors, 4 Gigabit Ethernet interfaces, 2-Gigabit FibreChannel interfaces, and approximately 250 GB of temporary disk.
