An array-oriented language: ZPL

• This language comes from Larry Snyder’s group at the University of Washington

• It has built-in abstractions for the common cases:

  • data layout including mesh boundaries
  • communications patterns, e.g. dimension broadcast
  • high level data operators, e.g. reduction and scan

• It is fairly general and exceptionally high level

• The best implementation uses C and shmem

  • The compiler optimizes communication quite well
