Validating Wrekavoc: A tool for heterogeneity emulation

Jens Gustedt
Emmanuel Jeannot


Experimental validation and testing of solutions designed for heterogeneous environment is a challenging issue. Wrekavoc is a tool for performing such validation. It runs unmodified applications on emulated multisite heterogeneous platforms. Therefore it downgrades the performance of the nodes (CPU and memory) and the interconnection network in a prescribed way. We report on new strategies to improve the accuracy of the network and memory models. Then, we present an experimental validation of the tool that compares executions of a variety of application code. The comparison of a real heterogeneous platform is done against the emulation of that platform with Wrekavoc. The measurements show that our approach allows for a close reproduction of the real measurements in the emulator., x-language = en, x-international-audience = yes
