More detailed hardware characteristics of the Niagara supercomputer can be found on this page. The compute nodes are accessed through a queueing system that allows jobs with a minimum of 15 minutes and a maximum of 24 hours and favours large jobs. Being designed for large parallel workloads, it has a fast interconnect consisting of EDR InfiniBand in a Dragonfly+ topology with Adaptive Routing. It was the 53rd fastest supercomputer on the TOP500 list of June 2018, and is at number 113 on the current list (June 2021).Įach node of the cluster has 188 GiB / 202 GB RAM per node (at least 4 GiB/core for user jobs and roughly 170 GiB/node at most).
The peak performance of the cluster is about 3.6 PFlops (6.25 PFlops theoretical). The Niagara cluster is a large cluster of 2,024 Lenovo SD530 servers each with 40 Intel "Skylake" cores at 2.4 GHz (1548 nodes) or 40 Intel "CascadeLake" cores at 2.5 GHz (476 nodes).
