Domain Specific Languages Domain Specific Languages (DSLs)
Programming language with restricted expressiveness for a particular domain
High-level, usually declarative, and deterministic
Most popular parallel PL
Most Science apps start with this PL
Enabled GPU innovation

HP DSLs Will Be Practical
Embedded DSLsFlexible embedding languages: Scala, F#
Metaprogramming (aka staging)
Blurring line between libraries and languages
DSL FrameworksSupport domain specific optimizations
Support parallelism and locality optimizations
Multiple backends
e.g. Spoofax, Rose, Delite, Terra/Lua
