There are two ways to connect to our systems. The traditional way will require you to install some software locally on your machine, including an SSH client, SFTP client, and optionally an X Windows server. The alternative is to use our zero-client web portal, OnDemand.
Once your account is set-up you will receive a welcome letter from us containing your username and default password, which will allow you to register your ARMSTRONG account.
The ARMSTRONG portal provides many services to OSC users, including:
ANSYS is an engineering package and support routine for general-purpose finite-element analysis: statics, heat transfer, mode frequency, stability analysis, magnetostatics, coupled field analysis, etc. Supports are provided by ANSYS, Inc.
The Assisted Model Building with Energy Refinement (AMBER) package contains many molecular simulation programs targeted at biomolecular systems. A wide variety of modelling techniques are available. It generally scales well on modest numbers of processors, and the GPU enabled CUDA programs are very efficient.
HyperWorks is a high-performance, comprehensive toolbox of CAE software for engineering design and simulation.
CUDA™ (Compute Unified Device Architecture) is a parallel computing platform and programming model developed by Nvidia that enables dramatic increases in computing performance by harnessing the power of the graphics processing unit (GPU).
FLUENT is a state-of-the-art computer program for modeling fluid flow and heat transfer in complex geometries.
Availability & Restrictions
FLUENT is available on both the Glenn and Oakley clusters. The following versions are available:
The AMD Core Math Library (ACML) is a set of numerical routines tuned specifically for AMD64 platform processors (including Opteron™ and Athlon™64 ). The routines, which are available via both FORTRAN 77 and C interfaces, include BLAS, LAPACK, FFT, RND, and many others.
Intel's implementation of the Message Passing Interface (MPI) library.
Ohio Supercomputer Center (OSC) has a variety of software applications to support all aspects of scientific research. We are actively updating this documentation to ensure it matches the state of the supercomputers. This page is currently missing some content; use
