Abstract:
This paper describes a method to improve the cache locality of
sequential programs by scheduling fine-grained threads. The algorithm
relies upon hints provided at the time of thread creation to determine
a thread execution order likely to reduce cache misses. This technique
may be particularly valuable when compiler-directed tiling is not
feasible. Experiments with several application programs, on two
systems with different cache structures, show that our thread
scheduling method can improve program performance by reducing
second-level cache misses.This technical report has been published as
