While Compute Canada clusters have a relatively high degree of uniformity, particularly the general purpose clusters, there are still significant distinctions that you need to be aware of when moving from cluster to another. This page will explain what is the same between clusters and what changes you'll need to adapt to on a new cluster. | While Compute Canada clusters have a relatively high degree of uniformity, particularly the general purpose clusters, there are still significant distinctions that you need to be aware of when moving from cluster to another.

While each of the general purpose clusters has a similar [[Storage_and_file_management | filesystem structure]], it is important to realize that there is no mirroring of data between the clusters. The contents of your home, scratch and project spaces is independent on each cluster. The [[Storage_and_file_management#Filesystem_quotas_and_policies | quota policies]] may also differ between clusters though in general not by much. If a group you work with has a special storage allocation on one cluster, for example <code>$HOME/projects/rrg-jsmith</code>, it will normally only be available on that particular cluster. Equally so, if your group requested that the default project space quota on a cluster be increased from 1 to 10 TB, this change will only have been made on that cluster. | |||

The collection of [[Utiliser_des_modules/en|globally installed modules]] is the same across all of our general purpose clusters, distributed using CVMFS. | |||
