Abstract
Embodiments relate to a prefetch threshold for cache restoration. An aspect includes determining, based on a task switch from an outgoing task to a current task in a processor, a prefetch threshold for a next task, the prefetch threshold corresponding to an expected runtime of the current task and an amount of time required to prefetch data for the next task. Another aspect includes starting prefetching for the next task while the current task is executing based on the prefetch threshold.
