Call for participation: Adopting a Common Ecosystem for DSL Development
BoF at SC21

Tuesday 16th November 2021 12:15pm - 1:15pm CST

Running hybrid: In room 222 and also via the conference online platform.

Domain Specific Languages (DSLs) are a powerful way of providing
programmer productivity and performance when developing HPC codes. The
enriched information enables effective exploitation of supercomputers,
which is especially important as we reach exascale due to the high
degrees of parallelism and complex heterogeneous architectures. DSLs,
however, are often developed in isolation, sharing little underlying
infrastructure, which can mean they are somewhat immature, suffering
from bugs, a potential lack of maintenance and lack of third party tooling.

In this BoF we will focus on how we, as a community, can consolidate our
efforts and look to develop a common DSL ecosystem. Such an activity
could be game-changing in providing application developers with mature,
feature rich, abstract programming environments enabling effective
exploitation of future HPC machines. However, the devil is in the detail
and there are many challenges that must be solved to develop and provide
such a solution. These include requirements driven by the application
developers, the perspectives of the DSL designers and what support they
need, and to the compilation stack and which are the most appropriate

Run as a collaboration between the xDSL ExCALIBUR project and University
of Warwick, it is the intention of this BoF to provide an interactive
session where we as the community can meet to discuss these aspects,
highlight existing activities already underway that could compliment
efforts here, and take the first step in developing a common unified
ecosystem for DSL development.
