How Is The Library Used?

• Portable C code optimized for Gnu C compiler
  • Hand coding using C, Fortran (via f2c), or Pascal (via p2c)
  • Compiler target using C as a "portable assembly language"
    • Tuples using register temporaries
    • Instruction-level analysis easily parameterized for machine differences, even heterogeneous clusters
    • E.g., PAPERS MPL compiler (Will Cohen at UAH)
• Usable for fine-grain MIMD, SIMD, and VLIW
• Can be used to augment PVM, MPI, etc.
