Grid Maintenance - May 2017

April 26, 2017

This is a reminder that the monthly Grid maintenance is scheduled for Monday, May 1st, from 8am until 12pm.

How will this affect you?

  • All sessions to the login nodes will be terminated (including terminal and NoMachine sessions)
  • All interactive sessions will be terminated
  • You will not be able to login to the grid
  • You will not be able to use NoMachine
  • Modules installed under Python v2.6 that include compiled code may need to be reinstalled under the new Python v2.7

Any currently pending jobs should not be affected.

Currently running non-interactive (batch) jobs may be affected if the job code makes separate, distinct calls to the Python binary. There is a remote chance that an early Python call will hit v2.6, and a later call will hit v2.7.

The actual work being performed is:

  • The terminal and NoMachine login nodes will be rebooted
  • The default Python will be upgraded to version 2.7

Installed Python v2.6 modules that included a compilation phase may need to be reinstalled under v2.7

o   *If you require continual usage of Python 2.6, please contact us for further instructions.*

Our next first-Monday-of-the-month maintenance will occur on June 5th, 2017.
