Omni Compiler Project

Omni Compiler is a collection of programs and libraries that allow users to build code transformation compilers. Omni Compiler is to translate C and Fortran programs with XcalableMP and OpenACC directives into parallel code suitable for compiling with a native compiler linked with Omni Compiler runtime library. Moreover, Omni Compiler supports XcalableACC programming model for accelerated cluster systems. Omni Compiler project is proceeded by Programming Environment Research Team of RIKEN Center for Computational Science and HPCS Lab. of University of Tsukuba, Japan.

Omni Compiler consists of following components.

XcalableMP is a directive-based language extension of C and Fortran for distributed memory systems. XcalableMP allows users to develop a parallel application and to tune its performance with minimal and simple notation.
OpenACC is a directive-based programming interface for accelerators such as GPGPU. OpenACC allows users to express the offloading of data and computations to accelerators to simplify the porting process for legacy CPU-based applications.
XcalableACC is a hybrid model of XcalableMP and OpenACC. XcalableACC defines directives that enable programmers to mix XMP and OpenACC directives to develop applications on accelerated cluster systems.
XcodeML is an intermediate code written in XML for C and Fortran languages.


Omni Compiler is an open source software, which has been developed on GitHub.
