Common data needed by routines is now with global scope. Resulting samples are accumulated first and later on outputted. This is a precondition step we need before introducing super master topology.
When there is only one node, then each worker directly outputs the results (vs. using a point-to-point communication for sending the results to the master process). When there are more than one node, then a second master is created in the same node where the global master resides, and results are outputted the same exact way as before (in that node only). This way the global master is released from the coordination of local sample generation, hence it can coordinate the generation among other nodes. Now the global master should not be the bottleneck.
When there is only one node, then a secondary master is not needed, meaning an extra MPI process is available for generating samples.
Workers located in master node now directly send the generated samples to the standard output. Master also generates samples when there is no other work to do. This happens in the master node only.
Makefile is preferred when installed CMake is lower than 3.5.1
