As a part of the reproducibility initiative at the SC20 conference, students participating in the Student Cluster Competition where given the reproducibility challenge, which is a directed reproducibility exercise that reproduces a paper from the previous year’s conference. At SC20, the paper, MemXCT: memory-centric X-ray CT reconstruction with massive parallelization (https://doi.org/10.1145/3295500.3356220), from SC19 was used. In the directed exercise, students were asked to reproduce performance characteristics of the research on a variety of architectures. This file contains the experimental setup and outputs of their work from the reproducibility challenge. It also includes the direction that students were given to the students for the exercise. The students then published their reports as polished critiques of the reproducibility of the original paper along with a new revision of the original paper, titled MemXCT: Design, Optimization, Scaling, and Reproducibility of X-Ray Tomography Imaging (https://doi.org/10.1109/TPDS.2021.3128032), in a Special Section of the IEEE Transactions on Parallel and Distributed Systems (TPDS). The paper along with the revised papers are available at https://ieeexplore.ieee.org/xpl/tocresult.jsp?isnumber=9696253&punumber=71.
