I found a brief thread about this, with no resolution, in the archives. I have tried to start both sge_qmaster and sge_schedd using a startupitem in /Library/Startupitems. If I run the item manually SystemStarter start GridEngine all is cool, but if I do a reboot, only sge_qmaster starts. Even worse, there are no messages logged for sge_schedd - it's like no attempt was made to run the daemon. I have experimented further, making a separate startup item for sge_schedd and making it dependent on sge_qmaster, but with the same result. I just get a message in the system log indicating that the script failed to run. I really hate situations like this. Anybody have any idea what's going on? In particular, if Wei Liu is listening: Did you ever get this problem resolved? Thanks! Randy Randy J. Zauhar, PhD Assoc.
