International Conference on Performance Engineering (ICPE) is the flagship conference for SPEC and a very important conference for the performance evaluation and engineering world at large. The CORE ranking list is used by researchers and administrators in many areas of the world to select top conferences. Thus, having ICPE listed in this rank is important for the continued success of the conference, and for the publication of work done in performance evaluation around the world. Petr Tůma worked diligently on the laborious process that is required to include ICPE in the official CORE ranking list. His contribution included learning the obscure CORE ranking application process, educating the RG Steering Committee, and then driving an extensive data-gathering process across the RG and the ICPE Steering Committee to secure support from high-ranking researchers in preparation for the final application package.
