ppOpen-HPC: Open Source Infrastructure for Development and Execution of Large-Scale Scientific Applications on Post-Peta-Scale Supercomputers with Automatic Tuning (AT)
We propose an open source infrastructure for development and execution of optimized and reliable simulation codes on post-peta (pp) scale parallel computers with heterogeneous computing nodes which consist of multicore CPU’s and accelerators., named “ppOpen-HPC”. ppOpen-HPC consists of various types of libraries, which covers various types of procedures for scientific computations. Source code developed on a PC with a single processor is linked with these libraries, and generated parallel code is optimized for post-peta scale system. Capability of automatic tuning is important and critical technology for further development on new architectures and maintenance of the framework.
