Abstract
Methods, apparatuses, and computer program products are provided for locking access to data storage shared by a plurality of compute nodes. Embodiments include maintaining, by a compute node, a queue of requests from requesting compute nodes of the plurality of compute nodes for access to the data storage, wherein possession of the queue represents possession of a mutual-exclusion lock on the data storage, the mutual-exclusion lock indicating exclusive permission for access to the data storage; and conveying, based on the order of requests in the queue, possession of the queue from the compute node to a next requesting compute node when the compute node no longer requires exclusive access to the data storage.
