GLPK

GLPK (GNU Linear Programming Kit) is a set of open source LP (linear programming) and MIP (mixed integer problem) routines written in ANSI C, which can be called from within C programs. 

Availability & Restrictions

GLPK is available to all OSC users without restriction. 

The following versions are available on OSC systems:

Managing Your Project

Principal Investigators of OSC projects are responsible for updating their authorized user list, their outside funding sources, and their publications and presentations that acknowledge OSC. All of these tasks can be accomplished through the ARMSTRONG portal (https://armstrong.osc.edu). PIs are also responsible for monitoring their project's Resource Unit balance and for submitting a proposal to the Allocations Committee of the Statewide Users Group before the balance goes negative.

CFX

CFX is a computational fluid dynamics (CFD) program for modeling fluid flow and heat transfer in a variety of applications.

System Email

Occasionally, jobs that experience problems may generate emails from staff or automated systems at the center with some information about the nature of the problem. These pages provide additional information about the various emails sent, and steps that can be taken to address the problem.

Out-of-Memory (OOM) or Excessive Memory Usage

Problem description

A common problem on our systems is for a user job to run a node out of memory or to use more than its allocated share of memory if the node is shared with other jobs.

If a job exhausts both the physical memory and the swap space on a node, it causes the node to crash. With a parallel job, there may be many nodes that crash. When a node crashes, the systems staff has to manually reboot and clean up the node. If other jobs were running on the same node, the users have to be notified that their jobs failed.
