System Overview

Accelerator Plus is a high-performance hierarchical scheduler designed for distributed High Performance Computing (HPC) environments.

Accelerator Plus is based on the patented concepts described in US Patent 9,658,893 about multi-layered resource scheduling.

The current implementation is designed to be run in conjunction with a base scheduler such as Accelerator, or Altair PBS Professional.

With its sub-millisecond latency, Accelerator Plus improves the throughput of difficult workloads, especially those consisting of large numbers of short duration jobs perhaps with complex dependencies, while off-loading the base scheduler. Accelerator Plus allows any user or group to have their own high-performance scheduler without requiring the intervention of the IT department. Since all computing resources are negotiated by means of the base scheduler, Accelerator Plus always obeys all policies established by IT with respect to sharing such resources.
