The past two months have been very good to us with five journal articles being accepted in something resembling a ketchup-effect. The most recent addition is an article entitled “Certifying Execution Time in Multicores” that was accepted by the Elsevier journal Science of Computer Programming. In essence, this article is a summary of the PhD dissertation of Vitor Rodrigues, whom I collaborated with over the past years. My main contribution to this work is proposing the latency-rate model as an abstraction of the service provided by a shared resource, such as a memory. We incorporated this model into Vitors timing analysis tool based on abstract interpretation to enable scalable timing analysis of multi-core platforms with shared resources.
