Contacts: Gwendolyn Bryson (, Liam Forbes ( will be offline for the week of February 6-10 per plans to expand the cluster. During this time 35 new nodes (Relion 1900v2 each w/ 28 cores, 128GB memory) will be added to the cluster. One new node will be allocated to the debug partition (making two total) and 34 to the standard partitions (for 66 total).
