Rapid Access Service

Our Rapid Access Service (RAS) allows Principal Investigators (PIs) to request a modest amount of storage and cloud resources without having to apply to the Resource Allocation Competitions (RAC). Many research groups can meet their needs by using the Rapid Access Service only.

Compute resources are available only for opportunistic use (no priority) to anyone with an active Compute Canada account.

If you need a CPU or GPU allocation (priority), or require larger quantities of storage and cloud resources than what is available via RAS, you must apply to one of our annual Resource Allocation Competitions. (See additional information about Compute allocations and resource scheduling).

PIs with a current RAC allocation are still able to request resources via RAS.

Please consult our Technical Glossary if you have questions about any of the terminology used below.

General questions can be emailed to our support team at any time.

Storage resources available via RAS

Users have access to different storage resources on most national systems without a RAC application. Visit this page for details about quotas available via RAS.

Please note:

  • Storage resources are only accessible with an active Compute Canada account.
  • /HOME and /SCRATCH storage are not allocated through RAC.
  • Storage resources may be available on regional legacy systems without a RAC allocation. These are documented on the regional websites linked from the Compute Canada wiki.
  • For details about cloud storage available via RAS, visit this page.

How to request RAS storage resources

PIs can request storage resources available via RAS by sending an email to our support team.

Cloud resources available via RAS

PIs may request access to modest amounts of cloud resources at any time and allow others with Compute Canada accounts to access these resources. 

  • To see resource limits that can be requested through RAS see the cloud RAS documentation on our technical wiki. 
  • For details on how to make a request for new, or access to, existing resources see the cloud documentation on our technical wiki.
