SmartSuspend Feature Overview

Jaryba SmartSuspend (SSR) is a grid workload management solution that enables executing jobs to be reliably suspended and resumed at will. While suspended, the job's hardware (CPU and memory) and license resources are released, making those resources available to other jobs. As a user space technology, SSR achieves this without any modification to the underlying operating system (OS) or the applications under management. Licenses, memory and CPU are cleanly reacquired when a job is resumed.
