Detailed Description

module contains the worker routine handling the communication and the calculation / creation of the configurations

• WORKER these are all TMC cores, instead of master core and maybe some idle cores
• divided in groups, in every group exists group master
  • there can be two kind of groups, one for exact energy calculation and one calculating configurational change using an approximate potential
• Algorithm:
  • group master receive messages and decide what to do,
  • (if nessesary) broadcast of working task to all other group members (needed for parallel CP2K)
  • process task, calculations of energy or configurational change
  • result, exist on group master, sent to master core Communication structure (master->worker, worker->master):
• message structure is defined in TMC message module
