Abstract in another language

The ECM (Execution-Cache-Memory) model is an analytic, resource-based performance model for steady-state loop code running on multicore processors. Starting from a machine model, which describes the interaction between the code and the hardware, and static code analysis, it allows an accurate prediction of the runtime of sequential loop code. Together with a scaling assumption, it also gives a performance scaling prediction. This poster summarizes the current state of practice in constructing and applying the ECM model, points out problems and open questions, and applies the model to three new and nontrivial use cases. For the first time, overlap assumptions for all relevant CPU architectures in high performance computing are presented.
