Frontenac is CAC's main compute cluster. Until March 31, allocations from the 2018 Resource Allocation Competition of Compute Canada ("RAC 2018"), ran on this cluster.
This cluster is not be among the allocatable system for the 2019 Compute Canada allocation round ("RAC 2019"). Therefore, operation of Frontenac is on a cost-recovery basis since April 1. For details about the fee structure, please see our Frontenac Fee Wiki page. This is an important change that affects both compute access and the usage of storage.
If you are looking for systems that offer cycles free of charge, please consult the available resources at Compute Canada. Allocations of larger resources require an application, but "opportunistic" use (Rapid Access Service or RAS) is available also.
Compute Ontario has kindly offered to provide temporary storage (located at the [Graham] Compute Cluster) for those of our current users who need to move their data and presently do not have sufficient allocation to accommodate them.
Note that the CAC team will continue to provide support for researchers from Queen's and other Ontario Universities, irrespective of the systems they are working on. Our main commitment is to the researchers, not the platform.

Migrating off the Frontenac cluster
Note: Any data on the Frontenac file system must be moved off the system by April 2019. Retention of data beyond that time requires an arrangement involving fees. Please consult our fees guide for details. The Arrangement has to be made before the deadline of April 1, 2019 to avoid data purges.
For technical information of how to upload/download data from our system, see our file transfer help page
Note that the responsibility of data migration lies with the user. We do not control access to the target systems and cannot do the data transfer for you. We will assist you with technical issues but you have to arrange for the disk space on the target system.
Unfortunately, operating expenses will no longer be covered by CFI MSI-2 resources. The only way we can continue to supply resources is by charging a fee to cover maintenance and operating costs. We do so on a cost recovery basis, i.e. we charge as much as we must, and as little as we can.
Data can be transferred to another system using scp/sftp from a command line or through a secure transfer client. Another option is to establish a Globus individual access point on our system. Please consult our guide about data transfer. Note that the transfer should be done using our login nodes (login.cac.queensu.ca) or a data transfer node we installed for this purpose (transfer.cac.queensu.ca). If you encounter issues with moving data, please contact us through our ticketing system.

- Q: Will user support continue ?
- A: Yes. Our team will continue to support researchers from Queen's and other Ontario Universities irrespective of the systems they are working on. Our main commitment is to the researcher and their science, not to the platform.
- Q: Who migrates ?
- A: All users who currently hold an hpcXXXX (Compute Canada) free account, and will not continue on a charged account.
- Q: How much would it cost to continue the system ?
- Q: Where can I continue to use resources for free ?
- A: Compute Canada systems offer free resources based on allocations from a competition (RAC), or to a limited extend on "opportunistic" usage (RAC).
- Q: Can I run my programs somewhere else?
- A: Most execution scripts, pipelines, etc will still work on another system, as Frontenac is very similar to other Compute Canada systems.
- Q: Do I copy my files over myself ?
- A: Yes. We cannot do the data transfer for you. We will assist you with technical issues, but we cannot arrange for permanent space on other systems.
- Q: I have a lot of data and don't know where to put it.
- A: We have made arrangements with SHARCNET to store data temporarily on Graham. You can use the default space allocations there to store your data, and ask for extended storage if necessary. Keep in mind that this is meant as a temporary solution before you move the data to the system where you continue your work.
- Q: Is this optional ?
- A: No. The move must be done by April 1, 2019, as we have to cover our operating and maintenance costs.
- Q: Can I decide when to move ?
- A: Yes, as long as the move is completed by April 1.
- Q: Will this disrupt my research ?
- A: We hope that you continue your research on our systems and pay the associated fees. In that case things will be continuing without any disruption. If you decide to move to another system that offers free access, you should plan the data migration as early as possible to smooth over any issues that the migration entails. We will do our best to assist you with this, but we cannot do it for you.
- Q: I have a RAC 2018. Does this apply to me ?
- A: Yes. The bulk of data has to be moved by April 2019. This is particularly important if you are a researcher outside Ontario. We may be able to help make arrangements prior to the onset of the 2019 allocation on a case-by-case basis. Contact us.
- Q: I have contributed hardware to CAC. Does this apply to me ?
- A: Contributed accounts were issued on the basis of a prior agreement and will not be subject to this as long as the agreement continues.
