| Specifications || The sites | | Specifications || 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 RAC | 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. Detailed updates to follow. | ||
