DescriptionSimulation is considered as the third pillar of
science, following experimentation and theory. Bridging
the native and simulated executions of parallel
applications is needed for attaining trustworthiness in
simulation results. Yet, bridging the native and
simulated executions of parallel applications is
challenging. This work proposes a methodology for
bridging the native and simulated executions of message
passing parallel applications on high performance
computing (HPC) systems in two steps: Expression of the
software characteristics, and representation and
verification of the hardware characteristics in the
simulation. This work exploits the capabilities of the
SimGrid [3] simulation toolkit’s interfaces to reduce
the effort of bridging the native and simulated
executions of a parallel application on an HPC system.
For an application from computer vision, the simulation
of its parallel execution using straightforward
parallelization on an HPC cluster approaches the native
performance with a minimum relative percentage
difference of 5.6%.
