ABSTRACT:
A method, information processing node, and a computer program storage product are provided for performing synchronization operations between participants of a program. Each participant includes at least one of a set of processes and a set of threads. Each participant in a first subset of participants of a program updates a portion of a first local vector that is local to the respective participant. Each participant in a second subset of participants of the program updates a portion of a second local vector that is local to the respective participant. The participants in the second subset exit the synchronization barrier in response to determining that all of the participants in the first subset have reached the synchronization barrier.
