=Major upgrade of our Advanced Research Computing infrastructure= | |||
Our Advanced Research Computing infrastructure is undergoing major changes to always provide better High Performance Computing (HPC) and Cloud services for Canadian researchers. This page will be regularly updated to keep you informed of the activities concerning the transition to the new equipment.<br> | |||
The infrastructure renewal will replace the nearly 80% of our current equipment that is approaching end-of-life. The new equipment will offer faster processing speeds, greater storage capacity, and improved reliability. | |||
The new equipment will offer | |||
The systems involved are | |||
*Arbutus, cloud | |||
*Béluga, compute cluster only (not cloud) | |||
*Cedar, compute cluster and cloud | |||
*Graham, compute cluster and cloud | |||
*Niagara, compute cluster | |||
=Technical specifications= | |||
Technical specifications for each new system will be provided further down this page in future updates. Generally, they will be similar in architecture to the current systems, but with considerably increased capacity and performance.<br> | |||
For example, we expect to have fewer compute nodes, but each node will have a significant increase in the number of its cores, for an overall increase in the total number of CPU cores. | |||
= | =Impacts= | ||
==System outages== | |||
An intense period of work will be conducted in the winter of 2024-2025 and spring of 2025. During the installation and the transition to the new systems, outages will be unavoidable due to constraints on space and electrical power. <br> | |||
We recommend that you consider the possibility of outages when you plan research programs, graduate examinations, etc. | |||
= | ==Resource Allocation Competition (RAC)== | ||
The [https://www.alliancecan.ca/en/services/advanced-research-computing/accessing-resources/resource-allocation-competition Resource Allocation Competition] will be impacted by this transition, but the application process remains the same. Application deadline this year is October 30, 2024.<br> | |||
2024/25 allocations will remain in effect on retiring clusters while each cluster remains in service. The 2025/26 allocations will be implemented everywhere once all new clusters are in service.<br> | |||
Because the old clusters will mostly be out of service before all new ones are available, if you hold both a 2024 and a 2025 RAC award you will experience a period when neither award is available to you. You will be able to compute with your default allocation (<code>def-xxxxxx</code>) on each new cluster as soon as it goes into service, but the 2025 RAC allocations will only become available when all new clusters are in service. | |||
