Abstract Contention for synchronization locks and delays waiting for synchronization events can substantially increase the running time of a parallel program. This makes it important to characterize the synchronization behavior of programs and to provide analysis tools to aid both the hardware and software designer in evaluating design alternatives. This paper describes a tracing facility that is incorporated into a synchronization package. This facility provides a portable means to accurately and efficiently characterize parallel programs. The behavior of several applications has been monitored uncovering program characteristics that make it difficult to achieve linear speedup. Our monitoring facility allows a programmer to determine the performance implications of the synchronization structure he has used, and it allows the architect to evaluate various hardware support mechanisms.
