Specifications

The Niagara Neptune Nodes are a special partition of the Niagara cluster accessible for special projects administered by SciNet.

Each node of the cluster has 484 GiB / 520 GB RAM per node (about 6 GiB/core for jobs and roughly 475 GiB/node). It has a fast interconnect consisting of HDR InfiniBand network that is part of Niagara's overall Dragonfly+ topology with Adaptive Routing. These are all compute nodes that can only be accessed through a queueing system that allows jobs with a minimum of 15 minutes and a maximum of 24 hours and favours large jobs. Jobs should be submitted from the Niagara login nodes.
