9!> \brief module contains the worker routine handling the communication and
10!> the calculation / creation of the configurations
11!> - WORKER these are all TMC cores, instead of master core
12!> and maybe some idle cores
13!> - divided in groups, in every group exists group master
14!> - there can be two kind of groups, one for exact energy calculation
15!> and one calculating configurational change using an approximate
16!> potential
17!> - Algorithm:
18!> - group master receive messages and decide what to do,
19!> - (if nessesary) broadcast of working task
20!> to all other group members (needed for parallel CP2K)
21!> - process task, calculations of energy or configurational change
22!> - result, exist on group master, sent to master core
23!> Communication structure (master->worker, worker->master):
24!> - message structure is defined in TMC message module
