The Stewardship and Advancement of Programming Systems and Tools (S4PST) is pleased to announce its updated portfolio for Fiscal Years (FY) 2027 and 2028. The following changes aim to align with the mission to deliver an impactful portfolio of programming systems and tools for the U.S. DOE.

Changes:

  1. New institutional member: we welcome William S. Moses, University of Illinois Urbana-Champaign, for his work on the Automatic Differentiation (AD) tool, Enzyme, and its integration with the LLVM compiler infrastructure. This work on differentiable programming transitions from incubation to core status in the S4PST portfolio.

  2. Julia for HPC and JACC work transitions from incubation to core status in the S4PST portfolio.

  3. OpenACC transitions from core to archival (no longer supported) status.

  4. Kokkos, GASNet, and Legion, will have an increase in their budget.

  5. No changes to MPICH, OpenMPI, OpenMP, LLVM.

  6. Incubation projects transition to research projects. e.g., AI for HPC, Kokkos for AI, and are no longer part of the S4PST portfolio.

Thus the new core portfolio for FY27/28 is:

  • OpenMP
  • LLVM
  • Kokkos
  • Fortran
  • Legion
  • OpenMPI
  • MPICH
  • UPC++/GASNet
  • Julia/JACC
  • Enzyme/AD
