Yet Another Stencil Kernel: A framework to facilitate exploration of the HPC stencil-performance design space, including

• Vector folding,
• Cache blocking,
• Memory layout,
• Loop construction,
• Temporal wave-front blocking,
• And many others.

YASK contains a specialized source-to-source translator to convert scalar C++ stencil code to SIMD-optimized code for Intel(R) Xeon Phi(TM) processors.

Supported Platforms

• 64-bit Linux
• Intel(R) Xeon Phi(TM) processor supporting the MIC_AVX512 instruction set.
• Intel(R) Xeon(R) processor supporting the AVX, AVX2, or CORE_AVX512 instruction sets
• Intel(R) Xeon Phi(TM) coprocessor supporting the Knights-Corner instruction set.

Pre-requisites:

• Intel(R) C++ compiler, https://software.intel.com/en-us/intel-parallel-studio-xe.
• Intel(R) Software Development Emulator, https://software.intel.com/en-us/articles/intel-software-development-emulator (optional: for functional testing if you don't have native ISA support).
• Intel(R) MPI Library, https://software.intel.com/en-us/intel-mpi-library, or equivalent (optional: for multi-core and multi-node operation).
• Perl 5.010 or later.
• Install all these pre-requisites and ensure that all tool and library paths are included in the proper environment variables.
• Git-clone or download the YASK source code.
