OnDemand

OnDemand is our "one stop shop" for access to our High Performance Computing resources. With OnDemand, you can upload and download files, create, edit, submit, and monitor jobs, run GUI applications, and connect via SSH, all via a web broswer, with no client software to install and configure.

HOWTO

Our HOWTO collection contains short tutorials that help you step through some of the common (but potentially confusing) tasks users may need to accomplish, that do not quite rise to the level of requiring more structured training materials. Items here may explain a procedure to follow, or present a "best practices" formula that we think may be helpful.

SuperLU

SuperLU is a library for the direct solution of large, sparse, nonsymmetric systems of linear equations on high performance machines.  It comes in two different flavors:  SuperLU_MT (multithreaded) for shared memory parallel machines and SuperLU_DIST for distributed memory parallel machines.

HOWTO: Install your own python modules

While we provide a number of Python modules, you may need a module we do not provide. If it is a commonly used module, or one that is particularly difficult to compile, you can contact OSC Help for assistance, but we have provided an example below showing how to build and install your own Python modules, and make them available inside of Python. Note, these instructions use "bash" shell syntax; this is our default shell, but if you are using something else (csh, tcsh, etc), some of the syntax may be different.

TurboVNC

Introduction

TurboVNC is an implementation of VNC optimized for 3D graphics rendering.  Like other VNC software, TurboVNC can be used to create a virtual desktop on a remote machine, which can be useful for visualizing CPU-intensive graphics produced remotely.

Availability

Version 1.900.1 is available on the Oakley cluster.  

Usage

In order to use the JasPer library, you must load the JasPer module into your environment.  To load the JasPer module, type the following command:

VTK

Introduction

The Visualization ToolKit (VTK) is an open source, freely available software system for 3D computer graphics, image processing and visualization. VTK consists of a C++ class library and several interpreted interface layers including Tcl/Tk, Java and Python.

TotalView Debugger

Introduction

TotalView is a symbolic debugger which supports threads, MPI, OpenMP, C/C++ and Fortran, plus mixed-language codes.  Advanced features include on-demand memory leak detection, heap allocation debugging and the Standard Template Library Viewer (STLView).  Other features like dive, a wide variety of breakpoints, the Message Queue Graph/Visualizer, powerful data analysis and control at the thread level give you the power you need to solve tough problems.  

Gnuplot

Introduction

Gnuplot is a portable command-line driven data and function plotting utility.  It was originally intended to allow scientists and students to visualize mathematical functions and data.  

Allocations and Accounts

The Ohio Supercomputer Center provides cycles to both academic and industrial clients. The methods for gaining access to the systems are different for each user community. Primarily, our users are Ohio-based and academic, and the vast majority of our cycles will continue to be consumed by Ohio-based academic users. Those cycles are allocated to academic PIs via an allocations process overseen by the Statewide Users Group, which evaluates applications via a peer review process.
