This repository contains an implementation of the RISE language and its Shine compiler (https://rise-lang.org/).

The source code for the compiler is organised into sub-packages of the shine package.

• DPIA contains the implementation of Data Parallel Idealised Algol. The Compilation sub-package contains the implementation to rewrite a high-level functional program into an imperative representation. Backend specific code generators for C, OpenMP and OpenCL are in their own packages. A paper describing DPIA is available at (https://arxiv.org/abs/1710.08332).

• C contains the C backend printing an imperative DPIA representation into C code.

• OpenMP contains the OpenMP backend printing an imperative DPIA representation into OpenMP code. The C backend is used to print most code. This package also defines extensions in form of additional patterns added to the RISE language and DPIA.

• OpenCL contains the OpenCL backend printing an imperative DPIA representation into OpenCL code. This package also defines extensions in form of additional patterns added to the RISE language and DPIA.

Prerequisits: Java 8+ SDK, git

1. Clone the shine repository to a directory of your choice that we call $SHINE_ROOT.
2. In $SHINE_ROOT, run setup.sh to download all required submodules.
3. Then run sbt compile (even if you want to use IDEA IntelliJ, because IntelliJ does not execute subproject dependencies correctly and the Executor needs to be built once in the beginning).

4. Download IDEA IntelliJ (http://www.jetbrains.com/idea/) and choose to install the Scala Plugin during setup.
5. Launch IntelliJ. From the menu choose File -> Open.... Then, select $SHINE_ROOT and press OK.
6. From the menu bar choose Run -> Edit Configurations.... Under Templates choose ScalaTest and add the following line to VM parameters: -Djava.library.path=lib/executor/lib/Executor/build -Xss26m (this will tell IntelliJ where to find the Executor library and use 26MB of thread stack size which is needed for arithmetic simplifactions sometimes).
