Lightweight Modular Staging (LMS) is a runtime code generation approach. This framework, LMS-Core, provides a library of core components for building high performance code generators and embedded compilers in Scala.

Closely related projects are Delite, a framework for heterogeneous parallel domain specific languages (DSLs), and Scala-Virtualized, a set of minimal extensions to the Scala compiler to make embedding DSLs more seamless.

Background:

• LMS website

• LMS paper

• Delite website

• Scala-Virtualized wiki

How to build:

1. Install the SBT build tool.

2. Run sbt test to run the test suite.

3. Run sbt publish-local to install LMS-Core for use in other projects.

Troubleshooting

If you get the following exception when running sbt publish-local:

java.lang.OutOfMemoryError: PermGen space
Error during sbt execution: java.lang.OutOfMemoryError: PermGen space
tsf-444-wpa-1-148:lms noetzli$ export SBT_OPTS=-XX:MaxPermSize=256m

Use export SBT_OPTS="-XX:MaxPermSize=256m -Xmx2048m".
