The Chapel Implementers and Users Workshop (CHIUW) is the primary annual gathering of the Chapel community. Its main goal is to bring developers and users of Chapel together on an regular basis to share progress and results with one another and with members of the broader parallel programming community. CHIUW typically also fosters new Chapel collaborations and endeavors through a code camp session held on the following day. Anyone with interest in Chapel is encouraged to attend CHIUW, from the seasoned user or developer to someone simply curious to learn more. This year, due to the COVID-19 pandemic, we are holding CHIUW in an online fom1at. This year, CHIUW received 13 submissions from 12 1ead authors, two of which were full research papers while the other 11 were extended abstracts. Each submitted extended abstract received four reviews from the program committee, while the research papers received 5-6. Due to our goal of making CHIUW as inclusive as possible, we ended up accepting eight of the submissions (including both papers) as full- length talks and tour as short talks (pending author interest), rejecting only one of the two submissions by the same lead author. After being accepted, one of the submissions upgraded from an extended abstract to a short paper with the program committee's approval. The accepted submissions can be found within these proceedings and describe recent work being done in improving Chapel's features, optimizing its performance, and using Chapel to target GPUs, as well as a variety of applications being pursued in Chapel including Computational Fluid Dynamics, graph algorithms such as Hypergraph Homology, and simulations of Ultralight Dark Matter.
