Grid Simulator (WRONJ problem)

About this app

When we compute a workload in a grid where the job scheduler that assigns the workload jobs to idle workers runs on a fixed number of execution threads, a performance slowdown can occur when the job scheduler is a bottleneck because the assignation tasks queue becomes a critical path of the process: we will call this issue the WRONJ (Workers at Rest On Next Job) problem.

This application can configure and simulate a virtual grid where we show this phenomenon in action.
