Automatic Port to OpenACC/OpenMP for Physical Parameterization in Climate and Weather Code Using the CLAW Compiler

2019 Supercomputing Frontiers and Innovations  
Large parts of the code can be ported using OpenACC compiler directives but for time-critical components such as physical parameterizations, code restructuring and optimizations specific to a hardware  ...  In an effort to retain a single source code for multiple target architectures, the CLAW Compiler and the CLAW Single Column Abstraction were introduced.  ...  We would like to show our gratitude to the OMNI Compiler Team at RIKEN CCS for their effort and support to provide a very useful open-source tool-chain.  ...
