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.

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.
The OSC-Springfield offices would officially open in April 2004. Over the next several months, OSC engineers would install the 16-MSP Cray X1 system, the Cray XD1 system and the 33-node Apple Xserve G5 Cluster at Springfield office. A 1-Gbit/s Ethernet WAN service linked the cluster to OSC’s remote-site hosts in Columbus.

PIVIn December, 2003, OSC engineers installed a 512-CPU Pentium 4 Linux Cluster. Replacing the AMD Athlon cluster, the P4 doubled the existing system’s power with a sizable increase in speed. With a theoretical peak of 2,457 gigaflops, the P4 cluster contained 256 dual-processor Pentium IV Xeon systems with four gigabytes of memory per node and 20 terabytes of aggregate disk space.
