UCI-GUIs should use the parameter window to set hash size or turn on logging.
Winboard GUIs have to use the commandline-options.

Available commandline options:
   -hash <size in MB> Sets size of transposition table.
                      Size will be rounded to next possible table size.
   -xboard            Use Xboard/Winboard to communicate with GUI
                      else use UCI to communicate with GUI.
   -log               Creates a log file in current directory.
