From Programming Paradigms A CRPC/MCNC Workshop -- April 10-13 1995. by Geoffrey C. Fox


Advantages
  • Very portable and scalable to SIMD and MIMD
  • Should be able to eventually handle ~all synchronous and loosely synchronous problems including ones that only run well on MIMD
  • Industry Standard has been adopted
    • High Performance Fortran (HPF)
    • With exception of Cray Research, all key MPP venors and ISV's have adopted
  • Builds on CMFortran, FortranD Vienna Fortran and other commercial and research experience
Disadvantages
  • Need to wait for production quality full feature compilers
  • Not all problems can be expressed in it and community is working on HPF extensions
