main()

This example demonstrates how a parallel (distributed) sgpp::datadriven::SparseGridMiner is constructed using a configuration file and how it is then used.

Initialize MPI, BLACS and ScaLAPACK

use immediately invoked lambda expression to get the path to a configuration file.

We need a factory class to actually build the sgpp::datadriven::SparseGridMiner.

The miner object is constructed by the factory from a supplied configuration file.

Once we have a configured miner object, we can start the learning process.

exit BLACS, MPI (in outer scope to ensure all blacs grids were destructed before)
