Arm big.LITTLE, migration decision

caff over 8 years ago

Hi everybody, I'm doing a presentation about ARM big.LITTLE Technology. What is the tracked load metric that is used to decide whether and when to allocate a thread to a big or LITTLE core?

ARM Energy Awareness Scheduling (EAS) technology is for that.

For task load tracking, there are two popular methods:

Per-Entity Load Tracking (PELT)

Window-Assisted Load Tracking (WALT)

See https://developer.arm.com/open-source/energy-aware-scheduling for an overview.
