Hi, Jim:
Thank you very much for you kindful reply. Acturally I have checked a lot
of tutorial ouput log files of namd on your webiste, which also have such
ouput. But my job will crash when it run one or two days. This job was
running on myrinet connection enviroment, on which hard disks are
dynamically mounted on the system. But it won't crash when I run it by using
TCP connection. I am wondering whether this is a issue.
Thanks a lot.
Jason
