Performance Portability Research Area

Tool Integration and Autotuning for SUPER Performance Optimization
Leads: Mary Hall, Allen Malony

Methods for performance optimization of petascale applications must address the
growing complexity of new HPC hardware/software environments that limit the ability
of manual efforts in successful performance problem triage, software transformation,
and static/dynamic parameter configuration. Greater performance tool integration and
tuning process automation are necessary to manage and share performance information,
to correctly generate multiple code variants, to conduct controlled performance
experiments, and to efficiently search and discover high-performant solutions,
thereby improving performance portability overall. SUPER is advancing autotuning
capabilities through the coupling of performance measurement, analysis, and database
tools, compiler and program translators, and autotuning frameworks.
