File system load problem

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

Explanation

Your jobs are causing problems with one of the network file servers. This is usually caused by submitting a large number of jobs that start at the same time and execute in lockstep.

Sent under these circumstances

These emails are sent by a staff member when the high load is traced to your jobs. Often the jobs have to be stopped or deleted.

To turn off the emails

You cannot turn off these emails. Please don’t ignore them because they report a problem that you must correct.

To prevent these problems

See the Knowledge Base article (coming soon) for suggestions on dealing with file system load problems.

For information on the different file systems available at OSC, see Available File Systems.

Notes

If you continue to submit jobs that cause these problems, your HPC account may be blocked.

For assistance

We will work with you to get your jobs running within the constraints of the system. Contact OSC Help for assistance. See our Support Services page for more contact information.
