Mp2

Availability: February 2012 - April 1, 2020

Login Node: mp2.calculcanada.ca

Globus Endpoint: computecanada#mammouth

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

Mp2 is now exclusive to researchers from the Université de Sherbrooke.

Mammouth-Mp2 is a heterogeneous and polyvalent cluster designed for ordinary computations; it is located at the Université de Sherbrooke.

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	Large space for storing temporary files during computations. 20 TB of space and 1M files per user. No backup system in place.
PROJECT Lustre filesystem 716.6 TB of space in total	This space is designed for sharing data among the members of a research group and for storing large amounts of data. 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

The Mellanox QDR (40 Gb/s) Infiniband network links together all of the cluster's nodes and is non-blocking for groups of 216 nodes and 5:1 for the rest of the cluster.
