Scheduling in a high-performance computing (HPC) system
First Claim
1. A non-transitory computer-readable medium encoded with logic for scheduling in a high-performance computer (HPC) system, wherein the logic operates when executed to:
- receive a call from a management engine operable to manage a cluster of nodes in a HPC system, the call specifying a request comprising a job for scheduling, the job comprising one or more processes for execution at one or more nodes in the cluster, the call further specifying a number of nodes for executing the job;
determine whether the request is spatial, compact, or nonspatial and noncompact, the request being spatial if the job assumes spatial relationships between nodes executing the job, the request being compact if the job assumes proximity between nodes executing the job, the request being nonspatial and noncompact if the job assumes no spatial relationships or proximity between nodes executing the job;
generate one or more combinations of nodes in the cluster, the one or more combinations generated according to whether the request is spatial, compact, or nonspatial and noncompact; and
communicate a return to the management engine, the return identifying one or more nodes in at least one combination of nodes in the cluster for executing the job.

Abstract
In one embodiment, a method for scheduling in a high-performance computing (HPC) system includes receiving a call from a management engine that manages a cluster of nodes in the HPC system. The call specifies a request including a job for scheduling. The method further includes determining whether the request is spatial, compact, or nonspatial and noncompact. The method further includes, if the request is spatial, generating one or more spatial combinations of nodes in the cluster and selecting one of the spatial combinations that is schedulable. The method further includes, if the request is compact, generating one or more compact combinations of nodes in the cluster and selecting one of the compact combinations that is schedulable. The method further includes, if the request is nonspatial and noncompact, identifying one or more schedulable nodes and generating a nonspatial and noncompact combination of nodes in the cluster.

35. A system for scheduling in a high-performance computing (HPC) system, the system comprising:
-
means for receiving a call from a management engine operable to manage a cluster of nodes in a HPC system, the call specifying a request comprising a job for scheduling, the job comprising one or more processes for execution at one or more nodes in the cluster, the call further specifying a number of nodes for executing the job; means for determining whether the request is spatial, compact, or nonspatial and noncompact, the request being spatial if the job assumes spatial relationships between nodes executing the job, the request being compact if the job assumes proximity between nodes executing the job, the request being nonspatial and noncompact if the job assumes no spatial relationships or proximity between nodes executing the job; means for generating one or more combinations of nodes in the cluster, the one or more combinations generated according to whether the request is spatial, compact, or nonspatial and noncompact; and means for communicating a return to the management engine, the return identifying one or more nodes in at least one combination of nodes in the cluster for executing the job.
