Barrier Synchronization on a Loaded SMP Using Two-Phase Waiting Algorithms
Little work has been done on the performance of barrier synchronization using two-phase blocking, as the common wisdom is that it is useless to spin if the total number of threads in the system exceeds the number of processors. We challenge this view and show that it may be beneficial to spin-wait if the spinning period is set to be a bit more than twice the context switch overhead (rather than...

In distributed memory multithreaded systems, the long memory laten ies and unpredi table syn hronization delays are tolerated by ontext swit hing, i.e., by suspending the urrent thread and swit hing the pro essor to another thread waiting for exe ution. Simple analyti al upper bounds on performan e measures are derived using throughput analysis and extreme values of some model parameters. These...
