Thanks for your reply
I dont understand "step number is at least as large as nstlist". can you some explain?

The first output you cite was written at step 100, of the 15M you asked for. nstlist is in your .mdp file. All this stuff really doesn't matter at all.

Furthermore, if the file system doesnt write the buffer to the destination screen/file, then does that mean there is a problem? for example
if it shows as the following:
15000000 steps,  30000.0 ps.

Not really. There's just some latency between the program writing the output and you being able to read it. If the program is allowed to exit normally, then all the buffers will be flushed eventually. Details vary from case to case and depend on your hardware and OS.

    15000000 steps,  30000.0 ps.
    step 100, will finish Sun Nov 27 19:11:00 2011

    Sometimes it shows as the following:
    15000000 steps,  30000.0 ps.
    That is, there is not "will finish Sun Nov 27 19:11:00 2011"
    sentence

    It only writes it when certain conditions are true (e.g. step
    number is at least as large as nstlist), and it only appears when
    the file system decides to write the buffer to the destination
    screen/file.

        I don't know what you mean.
