The BLAST programs are widely used tools for searching DNA and protein databases for sequence similarity to identify homologs to a query sequence. While often referred to as just "BLAST", this can really be thought of as a set of programs: blastp, blastn, blastx, tblastn, and tblastx.


Bioperl offers a set of perl modules which can be used for sequence manipulation. Knowledge of PERL programming is required.

Getting Connected

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.

Managing Your Account

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.

Availability and Restrictions

ANSYS is available on Oakley and Glenn Clusters. The versions currently available at OSC are:


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.

Availability and Restrictions

AMBER is available on Ruby, Oakley, and Glenn Clusters. The versions currently available at OSC are (S means serial executables, P means parallel, and C means CUDA):


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 and Restrictions

FLUENT is available on Oakley and Glenn Clusters. The versions currently available at OSC are:
