The Trillion Parameter Consortium (TPC) is a global, community-driven, open initiative that brings together researchers, technical practitioners, educators, trainees, and other stakeholders working across the fields of AI and HPC. There are currently 82 active member organizations within TPC, and all organizations are encouraged to apply for membership.
Participants include computer scientists, mathematicians, and computational scientists; domain experts from astronomy, physics, chemistry, biology, environment, materials, and climate science; and experts in large-scale computing systems, computational frameworks, data management, ethical considerations, and responsible AI practices.
TPC aims to advance and accelerate the responsible, open, and safe development of large-scale AI capabilities for scientific and engineering applications. Its community represents the intersection of AI and HPC, encompassing not only the science of AI and the use of AI for scientific discovery, but also the challenges of harnessing the necessary extreme scale systems spanning data and computation.
TPC is guided by an executive committee, a technical steering group, and a planning team — all comprising leaders from around the world. The executive committee was formed by TPC founders from North America (Rick Stevens, Argonne National Laboratory and The University of Chicago, USA), Asia-Pacific (Satoshi Matsuoka, RIKEN, Japan), and Europe (Mateo Valero, Barcelona Supercomputing Center, Spain).
An additional 22 leaders serve on the planning team and technical steering group, which are led by regional co-chairs. The planning team co-chairs are Charlie Catlett (USA), Fabrizio Gagliardi (Spain), and Kyoung-Sook Kim (Japan), while the technical steering group co-chairs are Ian Foster (USA), Laura Morselli (Italy), and Rio Yokota (Japan).
