A Domain-Specific Language and Editor for Parallel Particle Methods
Domain-specific languages (DSLs) are of increasing importance in scientific
high-performance computing to reduce development costs, raise the level of
abstraction and, thus, ease scientific programming. However, designing and
implementing DSLs is not an easy task, as it requires knowledge of the
application domain and experience in language engineering and compilers.
Consequently, many DSLs follow a weak approach using macros or text generators,
which lack many of the features that make a DSL a comfortable for programmers.
Some of these features---e.g., syntax highlighting, type inference, error
reporting, and code completion---are easily provided by language workbenches,
which combine language engineering techniques and tools in a common ecosystem.
In this paper, we present the Parallel Particle-Mesh Environment (PPME), a DSL
and development environment for numerical simulations based on particle methods
and hybrid particle-mesh methods. PPME uses the meta programming system (MPS),
a projectional language workbench. PPME is the successor of the Parallel
Particle-Mesh Language (PPML), a Fortran-based DSL that used conventional
implementation strategies. We analyze and compare both languages and
demonstrate how the programmer's experience can be improved using static
analyses and projectional editing. Furthermore, we present an explicit domain
model for particle abstractions and the first formal type system for particle
methods.Comment: Submitted to ACM Transactions on Mathematical Software on Dec. 25,

Metamorphic Domain-Specific Languages: A Journey Into the Shapes of a Language
External or internal domain-specific languages (DSLs) or (fluent) APIs?
Whoever you are -- a developer or a user of a DSL -- you usually have to choose
your side; you should not! What about metamorphic DSLs that change their shape
according to your needs? We report on our 4-years journey of providing the
"right" support (in the domain of feature modeling), leading us to develop an
external DSL, different shapes of an internal API, and maintain all these
languages. A key insight is that there is no one-size-fits-all solution or no
clear superiority of a solution compared to another. On the contrary, we found
that it does make sense to continue the maintenance of an external and internal
DSL. The vision that we foresee for the future of software languages is their
ability to be self-adaptable to the most appropriate shape (including the
corresponding integrated development environment) according to a particular
usage or task. We call metamorphic DSL such a language, able to change from one
shape to another shape
Application Software, Domain-Specific Languages, and Language Design Assistants
While application software does the real work, domain-specific languages
(DSLs) are tools to help produce it efficiently, and language design assistants
in turn are meta-tools to help produce DSLs quickly. DSLs are already in wide
use (HTML for web pages, Excel macros for spreadsheet applications, VHDL for
hardware design, ...), but many more will be needed for both new as well as
existing application domains. Language design assistants to help develop them
currently exist only in the basic form of language development systems. After a
quick look at domain-specific languages, and especially their relationship to
application libraries, we survey existing language development systems and give
an outline of future language design assistants.Comment: To be presented at SSGRR 2000, L'Aquila, Ital
Proceedings of the 3rd Workshop on Domain-Specific Language Design and Implementation (DSLDI 2015)
The goal of the DSLDI workshop is to bring together researchers and
practitioners interested in sharing ideas on how DSLs should be designed,
implemented, supported by tools, and applied in realistic application contexts.
We are both interested in discovering how already known domains such as graph
processing or machine learning can be best supported by DSLs, but also in
exploring new domains that could be targeted by DSLs. More generally, we are
interested in building a community that can drive forward the development of
modern DSLs. These informal post-proceedings contain the submitted talk
abstracts to the 3rd DSLDI workshop (DSLDI'15), and a summary of the panel
discussion on Language Composition
