We'd like to announce availability of a preliminary, open source,
interpreter implementing a small core of the Fortress programming
language. This interpreter runs on the JVM. You can download the
source code at:
http://fortress.sunsource.net/
Our intention is to grow this implementation over time, with the help
of university partners and other interested third parties. We expect
that many parts of this interpreter will be used as components of a
complete Fortress compiler, which is our long term goal.
Fortress is a new programming language designed for high-performance
computing (HPC) with high programmability. In order to explore
breakaway approaches to improving programmability, the Fortress
design has not been tied to legacy language syntax or semantics; all
aspects of HPC language design have been rethought from the ground
up. As a result, we are able to support features in Fortress such as
transactions, specification of locality, and implicit parallel
computation, as integral features built into the core of the
language. Features such as the Fortress component system and test
framework facilitate program assembly and testing, and enable
powerful compiler optimizations across library boundaries. Even the
syntax and type system of Fortress are custom-tailored to modern HPC
programming, supporting mathematical notation and static checking of
properties such as physical units and dimensions, static type
checking of multidimensional arrays and matrices, and definitions of
domain-specific language syntax in libraries. Moreover, Fortress has
been designed with the intent that it be a "growable" language,
gracefully supporting the addition of future language features. In
fact, much of the Fortress language itself (even the definition of
arrays and other basic types) is encoded in libraries atop a
relatively small core language.
