In an MPI program if all processes call a send routine followed by calling a rece send routine will definitely cause a deadlock? buffered mode synchronous mode standard mode ready mode A call to a synchronous MPI Send routine can be paired up by a call to an asynchronous MPI routine True False Which one of the following call to MPI Reduce function is most likely to be correct? MPI_Reduce(operand, result, 1, MPI_INT, MPI_MAX, 0, MPI_COMM_WORLD) MPI_Reduce(&operand, &operand, 1, MPI_INT, MPI_MAX, 0, MPI_COMM_WORLD) MPL _educe(&operand, &result, 1, int, MPI_MAX, 0, MPI_COMM_WORLD) MPI_Reduce(&operand, &result, 1, MPI_INT, MPI_MAX, 0, MPI_COMM_WORID): In MPI programming, it is a good practice to allow only one process to handle all l/O operations. True False
