Abstract
One embodiment of the present invention provides a system that generates code for a scout thread to prefetch data values for a main thread. During operation, the system compiles source code for a program to produce executable code for the program. This compilation process involves performing reuse analysis to identify prefetch candidates which are likely to be touched during execution of the program. Additionally, this compilation process produces executable code for the scout thread which contains prefetch instructions to prefetch the identified prefetch candidates for the main thread. In this way, the scout thread can subsequently be executed in parallel with the main thread in advance of where the main thread is executing to prefetch data items for the main thread.
