Graham (GP3)

GRAHAM is a heterogeneous cluster, suitable for a variety of workloads, and located at the University of Waterloo. It is named after Wes Graham, the first director of the Computing Centre at Waterloo. It was previously known as "GP3" and is still identified as such in the 2017 RAC documentation.

System evaluation is not yet completed as of November 2016. Anticipated specifications, based on Waterloo's RFP and bids received, include the following. This information is NOT GUARANTEED and might not be complete. It is provided for planning purposes.

The parallel filesystem, interconnects and external persistent storage (NDC-Waterloo) will be the same as Cedar's. There is a slightly different mix of compute nodes.

Types de noeuds et leurs caractéristiques

Noeuds de calcul de base:	Plus de 500 noeuds	128Go de mémoire chacun
Noeuds de calcul de type "large":	Plus de 100 noeuds	256Go de mémoire chacun
Noeuds à grande mémoire 512	À déterminer	512 Go de mémoire chacun
Noeuds à grande mémoire 3000	À déterminer	3 To de mémoire chacun

Tous les noeuds ci-dessus auront du stockage local.

Calcul Canada ne peut pas révéler les modèles ou spécifications des CPU à ce stade-ci.

Graham will have GPU's, but Compute Canada is not currently able to disclose specific details. The RFP used NVIDIA K80 as a baseline specification.

The completed system is expected to have over 25,000 cores.
