The application-facing user-level iting the generic language constructs of C++ and adding parallel programs. Though the implementation of the provide the front end semantics, it is nonetheless fully embedded in the C++ language and leverages a widely supported front end fiack end in C++, inher- that facilitate expressing distributed asynchronous uses C++ constructs unfamiliar to many programmers to subset of C++14 functionality (gcc >= 4.9, clang >= 3.5, icc > = 16). The rranslation layer leverages C++ to map the user's code onto the fiack encI runtime APT. The fiack end APT is a set of abstract classes and function signatures that iuntime systenr developers must implement in accordance with the specification require- ments in order to interface with application code written to the must link to a iuntime systenr that implements the abstract mentations will be external, drawing upon existing provided in the pARMAI code distribution.

However, a reference implementation will be The front end rranslation layer, and iback end APT are detailed herein. We also include a list of application requirements driving the specification (along with a list of the applications contributing to the requirements to date), a brief history of changes between previous versions of the specification, and summary of the planned changes in up- coming versions of the specification. Appendices walk the user through a more detailed set of examples of applications written in the PARMA front encI APII and provide additional technical details for those the interested reader.
