Purpose

Notify you that one or more of your jobs caused excessive load on one of the network file system directory servers.

Sample subject line

Your jobs on Oakley are causing excessive load on fs14

Apparent sender

OSC Help <OSCHelp@osc.edu> or an individual staff member

Purpose

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

Sample subject line

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

Apparent sender

OSC Help <OSCHelp@osc.edu>

Explanation

Your job failed and was not at fault. You should resubmit the job.

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.

Sample subject line

PBS JOB 944666.oak-batch.osc.edu

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.

Glenn, Oakley

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.
