Other languages:
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.

For transferring data by Globus, you should use the endpoint computecanada#mammouth, whereas tools like rsync and scp can simply use an ordinary login node.

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.
