摘要
Controlling access to a resource in a distributed computing system that includes nodes having a status field, a next field, a source data buffer, and that are characterized by a unique node identifier, where controlling access includes receiving a request for access to the resource implemented as an active message that includes the requesting node's unique node identifier, the value stored in the requesting node's source data buffer, and an instruction to perform a reduction operation with the value stored in the requesting node's source data buffer and the value stored in the receiving node's source data buffer; returning the requesting node's unique node identifier as a result of the reduction operation; and updating the status and next fields to identify the requesting node as a next node to have sole access to the resource.
