About P3HPC

Performance, Portability, and Productivity in HPC (P3HPC) events provide an opportunity for researchers and application developers to discuss their successes and failures in tackling the compelling problems that lie at the intersection of performance, portability and productivity (P3) in High-Performance Computing (HPC).

We are particularly interested in research that addresses the complexities of real-life applications and/or realistic workloads, the composibility challenges arising from bespoke solutions, and the desire to “future-proof” applications through an era of increased heterogeneity and new emerging architectures. The topic of P3 touches on many aspects of HPC software development, and attracts a wide range of experiences and perspectives, including those of compiler, language and runtime experts; performance engineers; and domain scientists.


The IEEE/ACM International Workshop on Performance, Portability and Productivity in HPC (P3HPC) has been run as part of the Supercomputing (SC) program since 2018. Papers submitted to the workshop are peer-reviewed, and accepted papers are published by the IEEE Technical Consortium on High Performance Computing (TCHPC) in the IEEE Xplore Digital Library.


The Performance, Portability and Productivity in HPC (P3HPC) Forum is an outgrowth of a successful series of events hosted by the U.S. Department of Energy (DOE) National Laboratories. Argonne, Lawrence Berkeley, Lawrence Livermore, Los Alamos, Oak Ridge, and Sandia National Laboratories all have Centers of Excellence (COE) where computational scientists from the labs and vendors partner to ensure that scientific applications can successfully use current and next-generation supercomputers. The first DOE Centers of Excellence Performance Portability Meeting was hosted in 2016; in 2020, its name was changed to align with the P3HPC Workshop.

The Forum is designed to promote discussion and feedback. As such, submissions range from preliminary results to completed studies previously published at a prior conference or workshop, and take a variety of forms: technical presentations; breakout sessions; panel discussions; and technical posters.

Call for Papers: 2022 P3HPC Workshop

The 2022 International Workshop on Performance, Portability, and Productivity in HPC (P3HPC) will be held in conjunction with SC22: The International Conference on High-Performance Computing, Networking, Storage, and Analysis on Sunday, November 13 2022 from 9:00AM – 5:30PM Central.

P3HPC Principles

A snapshot of the P3HPC principles is now available via the website.

P3HPC Principles - Draft for Input

The program committee for the 2021 P3HPC Workshop have prepared a draft document in an attempt to establish the key shared principles and expectations shared by all members of the P3HPC community, and capture the remaining sources of disagreement. Readers are encouraged to leave comments and suggestions directly in the document, or to contact members of the P3HPC commitee via e-mail. The principles will also be presented and discussed during the Healing the Gaps and Growing the Scope of Performance, Portability and Productivity panel that closes this year’s P3HPC workshop on November 14.
