Hello Nilay,
Yes, I could see Ruby being used while checkpointing. When I use the
flags "--debug-flags=ProtocolTrace,RubyGenerated" to confirm the same, I
see the debug output containing the state transitions which look like:
66240500: system.dir_cntrl2: [Directory_Controller 2], Time: 132481, state:
NO_F, event: PUTF, addr: [0x7fe80, line 0x7fe80]
66240500: system.dir_cntrl2: executing a_sendWriteBackAck
66240500: system.dir_cntrl2: executing i_popIncomingRequestQueue
66240500: system.dir_cntrl2: next_state: WB
