Availability: February 2012 (in operation until April 1, 2020)

Login Node: mp2.calculcanada.ca

Globus Endpoint: computecanada#mammouth

Data Transfer Node (rsync, scp, sftp,...) : mp2.calculcanada.ca

Mammouth-Mp2 is a heterogeneous and polyvalent cluster designed for ordinary computations; it is located at the Université de Sherbrooke. It is a legacy resource which is administered by the regional consortium Calcul Québec. It is not part of the new national clusters of Compute Canada.

Site-specific policies

• Each job must have a duration of at least one hour (at least five minutes for test jobs) and a user cannot have more than 1000 jobs (running and queued) at any given time. The maximum duration of a job is 168 hours (seven days).

• No GPUs.

Storage

HOME Lustre filesystem 79.6 TB of space in total	This space is small and cannot be expanded; you should use your project space for substantial storage needs. 50 GB of space and 500K files per user. There is a daily backup.
SCRATCH Lustre filesystem 358.3 TB of space in total	Grand espace pour stocker les fichiers temporaires pendant les calculs. 20 TB of space and 1M files per user. No backup system in place.
PROJECT Lustre filesystem 716.6 TB of space in total	Cet espace est conçu pour le partage de données entre membres d'un groupe et pour le stockage de beaucoup de données. 1 TB of space and 500K files per group. No backup system in place.

Pour les transferts de données par Globus, on devrait utiliser le point de chute computecanada#mammouth, alors que pour les outils comme rsync et scp, on peut utiliser un nœud de connexion.

High-performance interconnect

Le réseau Infiniband QDR (40 Gb/s) de Mellanox relie tous les nœuds de la grappe, non-bloquant sur 216 noeds, 5:1 pour le reste.
