CHIUW: Chapel Implementers and Users Workshop
Friday, May 23rd, 2014
Advance Program
CHIUW—the Chapel Implementers and Users Workshop, to be held in conjunction with IPDPS 2014—will be the first in what is anticipated to be 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.

| Abstract: MADNESS is a general-purpose numerical environment that sits upon a scalable runtime that consciously includes elements "borrowed" from other projects including Charm++ and the HPCS programming languages, including Chapel; it is also designed to be interoperable with "legacy" code. But as I have said to Chapel's architects several times, maintaining our own runtime is just an unpleasant transitional phase and we are looking for a permanent home—is that home Chapel? I'll give you some flavor of what MADNESS does and how, with the objective of starting a conversation and seeding collaborations. | |
