The case for the three R's of systems research: repeatability, reproducibility and rigor

Computer systems research spans sub-disciplines that include embedded systems, programming languages, network- ing, and operating systems. In this talk my contention is that a number of structural factors inhibit quality systems re- search. Symptoms of the problem include unrepeatable and unreproduced results as well as results that are either devoid of meaning or that measure the wrong thing. I will illustrate the impact of these issues on our research output with examples from the development and empirical evaluation of the Schism real-time garbage collection algorithm that is shipped with the FijiVM -- a Java virtual machine for embedded and mobile devices. I will argue that our field should fos- ter: repetition of results, independent reproduction, as well as rigorous evaluation. I will outline some baby steps taken by several computer conferences. In particular I will focus on the introduction of Artifact Evaluation Committees or AECs to ECOOP, OOPLSA, PLDI and soon POPL. The goal of the AECs is to encourage author to package the soft- ware artifacts that they used to support the claims made in their paper and to submit these artifacts for evaluation. AECs were carefully designed to provide positive feedback to the authors that take the time to create repeatable research.
