Recently Resolved Issues

Wed 5th September : Update of PP nodes completed.
Our systems team updated the pp nodes espp1 and espp2 by taking one node out of service at a time.
This work was completed, ahead of schedule, on Tuesday 18th September. Please contact the helpdesk if you experience any issues.

Upcoming Maintenance Sessions

Wednesday 26th September 09:00-17:00
At Risk
RDF maintenance - 3rd October 2018 09:00 - 17:00
The RDF filesystems including the archer frontends, Data Transfer Nodes and DAC will be unavailable 09:00 - 17:00 on 3rd October whilst engineers work to replace UPS batteries.
We apologise for the inconvenience that may be caused by this essential work.
ARCHER Modules deletion - 3rd October 2018
The Programming Environment January 2015 module set will be removed on ARCHER.
This was the default set on the system from April 2015 - March 2016.
The full list of modules to be removed are listed at http://www.archer.ac.uk/about-archer/news-events/news/2018-10-03-module_removal.php.

Live Usage/Queue Data by Job Length/Size

This section displays ARCHER usage and queue information broken down by the job class (class is based on size in nodes and run time in hours).

Queue Times by Job Size/Length

The heatmap below provides information on the mean queue times on ARCHER over past periods for different job sizes/lengths. The colour in the heatmap indicates the mean queue time as measured by scheduling coefficient for each class and the number in the box is the number of jobs of that class.

The scheduling coefficient is the ratio of run time to run time plus queue time and, as such, represents the fraction of the time in the queue that was spent running. A value of 1 indicates that the job started instantaneously and a value of 0.5 indicates that the job queued for the same amount of time that it ran for.

All periods are relative to the current date.

ARCHER scheduling coefficient.

Usage by Job Size/Length

The heatmap below provides information on the usage on ARCHER over past periods for different job sizes/lengths. The colour in the heatmap indicates the number of kAU expended for each class and the number in the box is the number of jobs of that class.

All periods are relative to the current date.
