SUMMARY:Parallel Runtime Interface for Fortran (PRIF): A Compiler/Runtime-
 Library Agnostic Interface to Support the Parallel Features of Fortran 202
 3
DESCRIPTION:Minisymposium\n\nKatherine Rasmussen and Damian Rouson (Lawren
 ce Berkeley National Laboratory)\n\nFortran 2023 natively supports single-
 program, multiple-data parallel programming with a partitioned global addr
 ess space and collective subroutines, synchronization, atomics, locks, and
  more. Each of the four actively developed compilers that support Fortran’
 s parallel features uses its own parallel runtime library. The Parallel Ru
 ntime Interface for Fortran (PRIF) proposes to liberate compiler developme
 nt from reliance on a single runtime and empower runtime developers to sup
 port more than one compiler. PRIF also aims to broaden the community of ru
 ntime developers to include the Fortran compiler’s users: Fortran programm
 ers. PRIF does so by specifying the interface in Fortran, which makes it a
 ttractive to write the parallel runtime library in Fortran. Additionally, 
 PRIF has been designed to be portable across both shared and distributed m
 emory, varying architectures, as well as different operating systems. In t
 his talk, I will describe the motivation behind the development of PRIF, d
 escribe the design of the interface itself and the benefits of adopting it
 . I will also provide a brief status report on the first PRIF implementati
