[GE users] Sort by sequence number question

    [ The following text is in the "iso-8859-1" character set. ]
    [ Your display is set for the "ISO-8859-10" character set.  ]
    [ Some special characters may be displayed incorrectly. ]

I'm sure it worked before, but somehow - the scheduler now keeps assigning jobs and to my desperation I'm starting to think I'm crazy. It seems to ignore my "sequence numbers" entirely at the moment.

I'll try fiddle with the "round robin" thing, but fill_up is what I really want.

Hi,

I remember this discussion:

http://gridengine.sunsource.net/servlets/ReadMsg?list=users&msgNo=20022

It didn't solve your setup problem?

PS: You could try to use $round_robin instead of $fill_up.
