CLAW Logo

The CLAW Project is an open-source project including a directive language specification and a reference compiler targeting performance portability in climate and weather application written in Fortran.

CLAW Compiler

The CLAW Compiler is a source-to-source translator working on the XcodeML intermediate representation. It implements the necessary transformation to the CLAW Directive Language Specifications. Intent of this language is to achieve performance portability on weather and climate code, especially for column- or point-wise computation.

CLAW X2T

CLAW X2T (XcodeML to XcodeML Translator) is the part in charge of the AST analysis and transformations based on the directives.

The Java documentation of the CLAW X2T libraries is available.

Contributing

The CLAW Project is welcoming contribution. More information can be found on the official repository. A Slack workspace is available for discussions.
