Dynamic Management of Resources (DMR, pronounced "dimmer") is a software framework designed to enable runtime dynamicity in distributed High-Performance Computing (HPC) applications. Traditional HPC workloads rely on a fixed number of processes for the entire duration of a job, which leads to resource underutilization, longer queue times, and unnecessary energy consumption. DMR addresses this limitation by allowing applications to dynamically expand or shrink in response to the state of the computing system and the application.
