Detailed Description

Allows information from every processor in a communicator, to be output in rank sequence.

The begin() method for processor of rank > 0 waits for receipt of a message from processor rank - 1. The end() method sends a message to processor rank + 1.

Usage:

MpiLogger logger;
logger.begin();
std::cout << "Print from processor " << MPI::COMM_WORLD.Get_rank() << std::endl;
logger.endl();
