Purpose

Notify you that one or more of your jobs was running on a compute node that crashed due to a system software problem.

Sample subject line

Failure of job(s) 919137 due to a system software problem at OSC

Apparent sender

OSC Help <OSCHelp@osc.edu>

Explanation

Your job failed and was not at fault. You should resubmit the job. Usually the problems are caused by another job running on the node.

Purpose

Notify you that one or more of your jobs caused compute nodes to crash with an out-of-memory error.

Sample subject line

Failure of job(s) 933014,933174 at OSC due to exhaustion of physical memory

Apparent sender

OSC Help <oschelp@osc.edu>

Purpose

Notify you when your job is deleted by an administrator.

Sample subject line

PBS JOB 9657213.opt-batch.osc.edu

Purpose

Notify you when your job terminates abnormally.

Sample subject line

PBS JOB 944666.oak-batch.osc.edu

Purpose

Notify you when your job begins or ends.

Quantum ESPRESSO is a program package for ab-initio molecular dynamics (MD) simulations and electronic structure calculations.  It is based on density-functional theory, plane waves, and pseudopotentials.

SSHing directly to a compute node at OSC - even if that node has been assigned to you in a current batch job - and starting VNC is an "unsafe" thing to do. When your batch job ends (and the node is assigned to other users), stray processes will be left behind and negatively impact other users. However, it is possible to use VNC on compute nodes safely.

This knowledge base is a collection of important, useful information about OSC systems that does not fit into a guide or tutorial, and is too long to be answered in a simple FAQ.

Ruby, named after the Ohio native actress Ruby Dee, is The Ohio Supercomputer Center's newest cluster.  An HP built, Intel® Xeon® processor-based supercomputer, Ruby provides almost the same amount of total computing power (~144 TF) as our former flagship system Oakley on less than half the number of nodes (240 nodes).  Ruby also features two distinct sets of hardware accelerators; 20 nodes are outfitted with NVIDIA® Tesla K40 and another 20 nodes feature Intel® Xeon® Phi coprocessors.

STAR-CCM+ provides the world’s most comprehensive engineering physics simulation inside a single integrated package. Much more than a CFD code, STAR‑CCM+ provides an engineering process for solving problems involving flow (of fluids and solids), heat transfer and stress. STAR‑CCM+ is unrivalled in its ability to tackle problems involving multi‑physics and complex geometries.  Support is provided by CD-adapco.
