This page includes a summary of differences to keep in mind when migrating jobs from Glenn to one of our other clusters.

TIP: Remember to check the menu to the right of the page for related pages with more information about Owens' specifics.

OSC's Owens cluster being installed in 2016 is a Dell-built, Intel® Xeon® processor-based supercomputer. More details will be forthcoming as we finalize facilities changes and deployment schedules.

Allinea Performance Reports is a simple tool to generate one single-page HTML report that presents overall performance characteristics of HPC applications. It supports pthreads, OpenMP, or MPI code on CPU, GPU, or MIC based architecture.

OSC provides Allinea Performance Reports and Allinea MAP to all OSC users. 

Many software packages require a license.  These licenses are usually made available via a license server, which allows software to check out necessary licenses.  In this document external refers to a license server that is not hosted inside OSC.

If you have such a software license server set up using a license manager, such as FlexNet, this guide will instruct you on the necessary steps to connect to and use the licenses at OSC.

Users who wish to host their software licenses inside OSC should consult OSC Help.

The Schrodinger molecular modeling software suite includes a number of popular programs focused on drug design and materials science but of general applicability, for example Glide, Jaguar, and MacroModel.  Maestro is the graphical user interface for the suite.  It allows the user to construct and graphically manipulate both simple and complex chemical structures,

MPI is a standard library for performing parallel processing using a distributed-memory model. The Oakley and Ruby clusters at OSC can use the OpenMPI implementation of the Message Passing Interface (MPI), which is based on MPICH.

Lustre is a file system known for its capabilities in high performance environments.  A central factor in its ability to achieve such a high perfomance is striping, where individual files are transparently split and stored on multiple underlying targets known as object storage targets (OSTs).  The distributed nature of the file system allows for faster read and write performance than is possible with traditional file systems.
