摘要:
Computer implemented method, system and computer usable program code for profiling the execution of an application that is both space- and time-efficient and highly accurate. A computer implemented method for profiling the execution of an application includes sampling execution characteristics of the application at a plurality of sampling points to provide samples, and deriving a calling context of the samples. The application is continuously executed between sampling points while additional profiling data is gathered.

A dual-mode prefetch system for implementing checkpoint tag prefetching includes: a data array for storing data fetched from cache memory; a set of cache tags identifying the data stored in the data array; a checkpoint tag array storing data identification information; and a cache controller with prefetch logic.

A cache management method using checkpoint tags in checkpoint mode includes steps of: receiving a request to save data; fetching at least one cache block including the data from cache memory; writing the data from the at least one cache block into the data array; writing a physical address and metadata of the cache block into an array of cache memory tags; and upon receipt of a restore request: fetching an identifier for the at least one cache block stored in the checkpoint tag array; reloading the cache memory with the at least one cache block in the checkpoint tag array; and switching to normal mode.
