Advance Program
CHIUW 2015—the ACM SIGPLAN second annual Chapel Implementers and Users Workshop—is the second in an annual series of workshops designed to bring developers and users of the Chapel language (https://chapel-lang.org) together to report on work being done with the language across the broad open-source community. Attendance is open to anyone interested in Chapel, from the most seasoned Chapel user or developer to someone simply curious to learn more.
Registration: See the FCRC registration site (select 1- or 1.5-day workshop).
