An eligible principal investigator (PI) heads a project account and can authorize/remove user accounts under the project account (please check our Allocations and Accounts documentation for more details). This document shows you how to identify users on a project account and check the status of each user.
Glenn Cluster Retired: March 24, 2016
The Glenn Cluster supercomputer has been retired from service to make way for a much more powerful new system. As an OSC client, the removal of the cluster will result in work being added to the heavy workload being handled by Oakley or Ruby, potentially impacting you.
Submitting a job without specifying the proper shell will return a warning like below:
sbatch: WARNING: Job script lacks first line beginning with #! shell. Injecting '#!/bin/bash' as first line of job script.
If an error is encountered, the job is rejected.
OSC's Owens cluster being installed in 2016 is a Dell-built, Intel® Xeon® processor-based supercomputer.
ARM MAP is a full scale profiler for HPC programs. We recommend using ARM MAP after reviewing reports from ARM Performance Reports. MAP supports pthreads, OpenMP, and MPI software on CPU, GPU, and MIC based architectures.
ARM Performance Reports is a simple tool used to generate a single-page HTML or plain text report that presents the overall performance characteristics of HPC applications. It supports pthreads, OpenMP, or MPI code on CPU, GPU, and MIC based architectures.
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, to apply molecular mechanics and dynamics techniques to evaluate the energies and geometries of molecules in vacu
MPI is a standard library for performing parallel processing using a distributed memory model. The Ruby, Owens, and Pitzer clusters at OSC can use the OpenMPI implementation of the Message Passing Interface (MPI).
PAPI provides the tool designer and application engineer with a consistent interface and methodology for use of the performance counter hardware found in most major microprocessors. PAPI enables software engineers to see, in near real time, the relation between software performance and processor events.
This software will be of interest only to HPC experts.
