Swift/T

An MPI-based workflow system

Last updated: 24 Jun 2025     |     Release: 1.6.6

Swift/T is an implicitly parallel programming language for composing external functions and command-line executables into massively parallel applications. The external functions may be calls to external programs, libraries, or scripting languages (via embedded interpreters) Thus, it is a workflow language for extreme-scale computing, capable of executing very large numbers (trillions) of tasks at high rates across the largest supercomputers.
