On April 23 at 10am PT, Jade Abraham will present their #HPSFCon Chapel demo in our weekly deep-dive meeting. While it will cover some basic features of the language, it will focus primarily on the expression of parallelism and locality.
To join, see: chapel-lang.org/calendar/

In this #HPSFCon talk, Engin Kayraklioglu argues that Chapel’s expressive parallelism & locality features not only make users’ lives easier, but also simplify compiler optimizations by providing semantic hints.
