SUMMARY:Clacc: Translating OpenACC to OpenMP in Clang
DESCRIPTION:Workshop\nProgram Transformation, Programming Systems, Worksho
 p Reg Pass\n\nClacc: Translating OpenACC to OpenMP in Clang\n\nDenny, Lee,
  Vetter\n\nOpenACC was launched in 2010 as a portable programming model fo
 r heterogeneous accelerators.  Although various implementations already ex
 ist, no extensible, open-source, production-quality compiler support is av
 ailable to the community.  This deficiency poses a serious risk for HPC ap
 plication developers targeting GPUs and other accelerators, and it limits 
 experimentation and progress for the OpenACC specification.  To address th
 is deficiency, Clacc is a recent effort funded by the US Exascale Computin
 g Project to develop production OpenACC compiler support for Clang and LLV
 M.  A key feature of the Clacc design is to translate OpenACC to OpenMP to
  build on Clang's existing OpenMP compiler and runtime support.  In this p
 aper, we describe the Clacc goals and design.  We also describe the challe
 nges that we have encountered so far in our prototyping efforts, and we pr
 esent some early performance results.
