- Determine if the CPU supports the CAT and CDP feature.
- The CAT is supported on the following 6 SKUs for Intel(R) Xeon(R) processor E5 v3 family: E5-2658 v3, E5-2658A v3, E5-2648L v3, E5-2628L v3, E5-2618L v3, and E5-2608L v3 and all Intel(R) Xeon(R) processor D SKUs.
- Configure the COS to define the amount of resources (cache space) available. This configuration is at the processor level and is common to all logical processors.
- Associate each logical processor with an available COS.
- Run the application on the logical processor that uses the desired COS
