Which of the following statement is incorrect for parallel virtual machine (PVM)?

  1. AThe PVM communication model asynchronous blocking send, asynchronous blocking receive, and non-blocking receive function.
  2. BMessage buffers are allocated dynamically
  3. CThe PVM communication model assumes that any task can send a message to any other PVM task and that there is no limit to the size or number of such messages

Show answerHide answer

Correct answer: (D) In PVM model, the message order is not preserved.

Explanation

PVM provides fault tolerance through dynamic addition and deletion of hosts/processes, and message buffers are allocated dynamically. PVM guarantees that message order between any pair of tasks is preserved, so statement (d) is incorrect.
