Author Description

The Workshop on Practical Reproducible Evaluation of Computer Systems (P-RECS) focuses heavily on practical, actionable aspects of reproducibility in broad areas of computational science and data exploration, with special emphasis on issues in which community collaboration can be essential for adopting novel methodologies, techniques and frameworks aimed at addressing some of the challenges we face today. The workshop brings together researchers and experts to share experiences and advance the state of the art in the reproducible evaluation of computer systems, featuring contributed papers and invited talks. This 4th edition of the workshop (P-RECS '21) took place as a half-day virtual event. Due to the COVID-19 pandemic, putting together P-RECS'21 took extra effort this year, as the organizer did their best to recreate the participatory atmosphere of the three previous editions. We would like to thank all authors who submitted to the workshop. The diverse submission and selection assure interesting discussions and most importantly out-of-the-box thinking and generation of new ideas during the workshop. We are grateful to the program committee who worked very hard in reviewing papers and providing feedback for authors.
