Abstract
Large computer systems, like those in the TOP 500 ranking, comprise about hundreds of thousands cores. Simulating application execution in these systems is very complex and costly. This article explores the option of using application skeletons, together with an analytic simulator, to study the performance of these large systems. With this aim, the Dimemas simulator has been enhanced with the capability of simulating application skeletons. This enhancement allows simulating the skeleton of Lulesh, an application with 90k processes in a single day. In addition, it also generates traces, which is of great value to validate skeletons and simulations.
