GSoC 2017 Geant HPC workload balancer.

Task

Create HPC layer for GeantV project. GeantV is application for physics simulation and it had only single-node implementation. Our task was to create system that is aware about multiple hosts and could use allocated resources and process more events in a more efficient manner.

Code
