Ruby, named after the Ohio native actress Ruby Dee, is The Ohio Supercomputer Center's newest cluster.  An HP built, Intel® Xeon® processor-based supercomputer, Ruby provides almost the same amount of total computing power (~144 TF) as our former flagship system Oakley on less than half the number of nodes (240 nodes).  Ruby also features two distinct sets of hardware accelerators; 20 nodes are outfitted with NVIDIA® Tesla K40 and another 20 nodes feature Intel® Xeon® Phi coprocessors.

STAR-CCM+ provides the world’s most comprehensive engineering physics simulation inside a single integrated package. Much more than a CFD code, STAR‑CCM+ provides an engineering process for solving problems involving flow (of fluids and solids), heat transfer and stress. STAR‑CCM+ is unrivalled in its ability to tackle problems involving multi‑physics and complex geometries.  Support is provided by CD-adapco.

OSC Help consists of technical support and consulting services for OSC's high performance computing resources. Members of OSC's HPC Client Services group staff OSC Help.

Before contacting OSC Help, please check to see if your question is answered in either the FAQ or the Knowledge Base. Many of the questions asked by both new and experienced OSC users are answered in these web pages.

MPJ-Express is a Java library that provides message passing capabilities for parallel computing in Java applications.

MPJ-Express is available on Oakley.

We provide a number of web portals for our user community.

ARMSTRONG allows users to monitor their account summary information – RU balances and usage. In addition, PIs can manage their authorized users and keep their grants and publications up to date.

Description

This two hour workshop will provide an introduction to OSC resources and how to access them. Topics include:

  • High performance computing concepts.
  • Hardware and software available at OSC.
  • Getting allocations and accounts.
  • How to connect and log in.
  • How to move data on and off the systems.
  • Introduction to batch processing.
  • Storage and file systems.

Optional hands-on participation: 

OSC offers perioding training both at our facility and at universities across the state on a variety of topics. Additionally, we will partner with other organizations to enable our users to access additional training resources. Here you can find copies of the materials from recent training events.

OSC HPC resources use an operating system called "Linux", which is a UNIX-based operating system, first released on 5 October 1991. Linux is by a wide margin the most popular operating system choice for supercomputing, with over 90% of the Top 500 list running some variant of it. In fact, many common devices run Linux variant operating systems, including game consoles, tablets, routers, and even Android-based smartphones.

We are providing a collection of tutorials to allow self-paced training on various aspects of using OSC resources. Please contact us if you feel there is a specific tutorial that would be of use to the community.

OpenACC is a standard for parallel programming on accelerators, such as Nvidia GPUs and Intel Phi. It consists primarily of a set of compiler directives for executing code on the accelerator, in C and Fortran. OpenACC is currently only supported by the PGI compilers installed on OSC systems.
