Question

Which of the following is not valid with reference to Message Passing Interface(MPI)?

• A. MPI can run on any hardware platform
• B. The programming model is a distributed memory model
• C. All parallelism is implicit
• D. MPI- Comm - Size returns the total number of MPI processes in specified communication

Answer 1

Answer must be C

• Message Passing Interface (MPI) is a standardized and portable message-passing system
•  it has become a de facto standard for communication among processes that model a parallel program running on a distributed memory system.
• It can run on any hardare platform. It is Portable ,Efficient, Flexible
• Communicator objects connect groups of processes in the MPI session. Each communicator gives each contained process an independent identifier and arranges its contained processes in an ordered topology.
• MPI_Comm_Size returns the total number of MPI processes in specified communication
