New paper: Surrogate Applications for Multicore Contention Modeling

An academic paper featuring work from Rapita's CEO Dr. Guillem Bernat has been published in the IEEE Transactions on Emerging Topics in Computing journal.

This paper is now available to download directly from IEEE's website at the following link: https://ieeexplore.ieee.org/document/8408556.

The paper was co-authored by experts from Barcelona Supercomputing Center: Gabriel Fernandez, Jaume Abella and Francisco J. Cazorla.

In this paper a new modeling approach for multicore systems is proposed, which is tailored for a specific processor in the space domain, that simplifies time budgeting in EDP by developing surrogate applications and an automatic framework to generate them.

This research is related to the MACH¹⁷⁸ solution offered by Rapita. Specifically, the Surrogate RapiDaemon tool which automatically generates a combination of RapiDaemons that mimics the interference profile generated by your real application as it runs on your multicore system. This reduces the effort needed to estimate worst-case timing behavior by letting you bound your analysis by testing your applications against realistic interference profiles.
