We present a new technique, early phase termination, for eliminating idle processors in parallel computations that use barrier synchronization. This technique simply terminates ea...
Software distributed-shared-memory (DSM) systems providean appealingtarget for parallelizing compilers due to their flexibility. Previous studies demonstrate such systems can prov...
The performance of the barrier operation can be crucial for many parallel codes. Especially distributed shared memory systems have to synchronize frequently to ensure the proper o...
