31. What looks like a message passed between two distant minds is all a matter of projection. 32. In the message passing approach, the user process constructs a message, that describes the desired service. 33. Message passing can be efficiently implemented via symmetric multiprocessing, with or without shared memory cache coherence.34. The client library provides for high performance access via the message passing interface ( MPI ). 35. Another Java message passing system is MPJ Express. 36. Carl Hewitt, Beppe Attardi, and Henry Lieberman [ 1979 ] developed proposals for delegation in message passing . 37. In message passing , any global communication ( such as reduction or scatter ) may imply a barrier. 38. Asynchronous message passing requires additional capabilities for storing and retransmitting data for systems that may not run concurrently. 39. The message passed on by her friend in Albany was : " Let that all be passed now. 40. Specific tools may be used to simulate, visualize and understand the performance of message passing on computer clusters.
