Nibi, the Anishinaabemowin word for water, is the successor of Graham and a general purpose cluster of 134,400 CPU cores and 288 H100 NVIDIA GPUs built by [https://www.hypertec.com/ Hypertec], hosted and operated by [https://www.sharcnet.ca/ SHARCNET] at University of Waterloo. It is expected that Nibi will come online by July 1, 2025.
=Storage=
Parallel storage: 25 petabytes, all [https://en.wikipedia.org/wiki/Solid-state_drive SSD] from [https://www.vastdata.com/ VAST Data] for /home
, /project
and /scratch
.
This is the same storage as being used by miniGraham.
=Interconnect fabric=
* Nokia 200/400G ethernet
** 200 Gbit/s network bandwidth for CPU nodes.
** 400 Gbit/s non-blocking network bandwidth between all Nvidia GPU nodes.
** 200 Gbit/s network bandwidth between all AMD GPU nodes.
** 24x100 Gbit/s connection to the VAST storage nodes.
** 2:1 blocking at 400 Gbit/s uplinks for all compute nodes.
