Abstract
In multi-threaded or multi-processor computing systems, a deadlock may occur when two or more processes or threads are unable to proceed because they are each waiting for a resource that the other holds. As a result, progress is halted because conflicting entities are stuck in a circular dependency, and none can release the resources they hold to let the others continue. Systems and methods are provided wherein a resource reservation is carried out in two steps. The first step causes query nodes to add an identifier to a queue and, upon a request and the identifier being in a first position, a non-sharable resource is reserved. As a result, non-sharable resources are reserved in order and when needed, thereby preventing deadlocks.
