The Buffer


Up: Sending and Receiving messages Next: Generalizing the Buffer Description Previous: Current Message-Passing

Sending and receiving only a contiguous array of bytes:

  • hides the real data structure from hardware which might be able to handle it directly
  • requires pre-packing dispersed data
    -- rows of a matrix stored columnwise
    -- general collections of structures

  • prevents communications between machines with different representations (even lengths) for same data type
