Artemis Hardware
- Stephen Kolmann
Artemis is a 7588-core InfiniBand cluster comprised of the following nodes. Some of these nodes are reserved for research groups who won a "Grand Challenge" node allocation, or who purchased compute nodes for their research group or school and are having them hosted in Artemis. See the below table for a summary of available resources in Artemis

1 Jobs that are for I/O workloads or data transfer. Compute jobs will be terminated.
2 Interactive jobs are jobs where you have interactive access to a compute node. The PBS Pro node is exactly like a compute node, and the NoMachine nodes are for opening programs with GUIs where graphics processing is done server-side.
3 "Scavenger" jobs are low-priority jobs that run using idle resources in Artemis Grand Challenge scheme winners allocations. All Artemis users are welcome to submit scavenger jobs, however they will be terminated before finishing if a Grand Challenge allocation member submits work to their allocation and requires resources being used by a scavenger job.
Core allocations
Some Artemis nodes are reserved for certain groups. These nodes are either granted to researchers who won dedicated access to compute nodes as part of the Artemis Grand Challenge scheme, or who have ownership of compute nodes and choose to have them hosted in Artemis. As of March 2018, 1800 cores are allocated to Artemis Grand Challenge scheme winners, and 1136 cores and 80 V100 GPUs are owned by groups who have chosen to host compute resources in Artemis.Â
