Managing nodes in a high-performance computing system using a node registrar

Abstract

A method of managing nodes in a high-performance computing (HPC) system, which includes a management subsystem and a job scheduler subsystem, includes providing a node registrar subsystem. Logical node management functions are performed with the node registrar subsystem. Other management functions are performed with the management subsystem using the node registrar subsystem. Job scheduling functions are performed with the job scheduler subsystem using the node registrar subsystem.
