We have 4 CE’s available for submission and 1 CE for testing against, they all run Nordugrid ARC Compute Element Software. Information about ARC CE can be found at http://www.nordugrid.org/arc/ce/
Please be aware that from 23rd April 2026 11am all Compute Elements are ARC REST submission only, we not longer accept GridFTP jobs we also submit to the CE using the default REST interface (No longer require 8443).
For information on what nodes we have please see the Grid Nodes Resources page.
Test
Test CEs can only access specific nodes to the individual test setup.
CE-TEST
This is a test CE to allow you to test your job submission.
There are 2 test nodes with 1 core each and 4GB of RAM (2 single core jobs at 4GB max) with a max run time of 20minutes. This should be long enough to test your submission method and any get/copy/sync scripts prior to actual compute jobs.
