Detailed Description

template<class TopoDiscoveryStrategy>
class ManyMasterSplit< TopoDiscoveryStrategy >

A very simple splitting strategy where we have a one core optimizer and pilot (and k of those "islands") and many-core worker groups. The number of islands and co-workers is retrieved from the passed command line arguments:

• num-masters
• num-coworkers
