One Line Summary

Using the scheduler's ASYM_PACKING feature for the handling of cores with different maximum turbo frequencies


With Intel® Turbo Boost Max Technology 3.0, single-threaded performance is optimized by identifying processor’s fastest core and running critical workloads on it. This presentation gives overview of implementation using ACPI CPPC and scheduler ASYM_PACKING feature.
