45: * Format of communication is specified in [Simple Parallel Exec#Protocol] section
46: - initialisation: for every slave: try to start client (ssh). If it fails: check ssh connection with dummy ssh command. Success -> copy client to slave using scp and try to start it.
47: - on http request for configuration: reply client configuration (i.e. worker name, MD5 checksum and what to do on exit)
48: - on http request for worker executeable: reply with the binary for the right platform
49: - on http request for new task: reply with the next command to execute and all parameters.
50: - on http request for statistics (normal website): reply statistics webpage
51: - on post: validate result, mark task as completed and collect results
52: - no more task to process: exit and display statistics.
53: 1.1 Client
54: * Format of communication is specified in [Simple Parallel Exec#Protocol] section
55: * gets via command line: Session ID, server URL and port
56: - register at the server and fetch configuration
57: - check for the worker: if not already at local filesystem or the MD5 checksum is wrong: fetch it (for own platform) from the server
58: - fetch a task
59: - run worker
60: - check return code: if failed -> Post failture otherwise take the results and post them.
61: - fetch next task
62: - die if there is no more task or the server is not responding.
63: * different settings for termination: delete executeable (if fetched), delete the client program, delete results?
