Abstract
Official abstract text for this publication.
Systems, methods, and other embodiments associated with avoiding resource blockages and hang states are described. One example computer-implemented method for a computing system includes determining that a first process is waiting for a resource and is in a blocked state. The resource that the first process is waiting for is identified. A blocking process that is holding the resource is then identified. A priority of the blocking process is compared with a priority the first process. If the priority of the blocking process is lower than the priority of the first process, the priority of the blocking process is increased. In this manner the blocking process can be scheduled for execution sooner and thus release the resource.
First claim
Opening claim text (preview).
What is claimed is: 1. A computer-implemented method for a computing system, the method comprising: determining, by at least a processor, that a first process is waiting for a resource and that the first process is in a blocked state by accessing process state information from a shared global memory, where the process state information identifies processes and a current state of each process, where the shared global memory is shared and accessible by multiple nodes in the computin…
