CHIUW 2019

About
Program

CHIUW 2019 is the sixth annual Chapel Implementers and Users Workshop, held in conjunction with PLDI 2019 and ACM FCRC 2019, and sponsored by ACM SIGPLAN. CHIUW’s goal is to serve as a forum where users and developers of the Chapel language (https://chapel-lang.org) can gather to exchange ideas and report on work being done with Chapel and in support of it. Anyone is welcome to attend, from long-term Chapel enthusiasts to those simply curious to learn more.
