Grid Maintenance - July 2017

June 29, 2017

Due to the July 4th holiday, this is a reminder that the next monthly Grid maintenance is scheduled for Monday, July 10th, from 8am until 12pm.


How will this affect you?

  • ALL running jobs (interactive and batch) will be terminated
  • Any pending jobs will be paused prior to reboots and released afterwards
  • All sessions to the login nodes will be terminated (including terminal and NoMachine sessions)
  • You will not be able to login to the grid or use NoMachine

The actual work being performed is:

  • Reboot of the compute and login nodes (including NoMachine), as well as a reboot of the MariaDB server
  • Python 2.7 as a part of the Anaconda suite will replace the current Python 2.7 installation

What is happening?

  • An important security patch needs to be applied to all machines that are part of the compute grid
  • Providing Python 2.7 as a part of the Anaconda suite offers a richer set of additional Python packages and tighter integration with matplotlib, pandas, scipy, and other research tools

***Our next first-Monday-of-the-month maintenance will occur on Monday, August 7th, 2017.***
