Welcome to the ARC/Cloud renewal transition documentation for the Digital Research Alliance of Canada (the Alliance). This is the primary source for users with questions about the upgrade of our HPC/Cloud infrastructure. The upgrade will replace the nearly 80% of our current HPC and Community Cloud equipment which is approaching end-of-life. | Welcome to the ARC/Cloud renewal transition documentation for the Digital Research Alliance of Canada (the Alliance).

The systems being replaced are [[Arbutus]], [[Béluga]], [[Cedar]], [[Graham]] and [[Niagara]]. The new systems will be broadly comparable to the old systems, but with significantly increased capacity. | The systems being replaced are [[Arbutus]], [[Béluga]], [[Cedar]], [[Graham]] and [[Niagara]].

This renewal will be implemented during an intense period in the winter of 2024-2025. Constraints on space and electrical power mean that there will have to be service outages during the installation and transition to the new systems. Each site will develop a transition plan for their new system. We expect to hear more details in the autumn and will continue to update this landing page as those details become known. | This renewal will be implemented during an intense period in the winter of 2024-2025.

The sites cannot yet provide detailed technical specifications of the new systems. Generally, the new systems will be similar in architecture to the old systems but with considerably increased capacity and performance. For instance, we expect to have fewer compute nodes, but each node will have a significant increase in the number of cores due to the increase in the size of multi-core CPUs since 2017. | The sites cannot yet provide detailed technical specifications of the new systems.

The Resource Allocation Competition (RAC) and RAC renewals will be affected by this transition, but we are not changing the normal RAC process. Expect to see the usual announcements for the competition in September 2024. We expect to implement the 2025/26 allocations on the new machines when they become available so there may be some delay in RAC implementation. See RAC documentation available [https://www.alliancecan.ca/en/services/advanced-research-computing/accessing-resources/resource-allocation-competition here]. | The Resource Allocation Competition (RAC) and RAC renewals will be affected by this transition, but we are not changing the normal RAC process.

We will do our best to limit overlapping outages, but we are very constrained by delivery schedules and funding deadlines so there will probably be periods when many of our systems are simultaneously out. We’ll communicate all outages as early as possible. | We will do our best to limit overlapping outages, but we are very constrained by delivery schedules and funding deadlines so there will probably be periods when many of our systems are simultaneously out.
