Jeff,
when the TM in SGE comes true, I think the already implemented PBS
startup in LAM could be used. But it will still take some time, until
this comes true.
So I will look into the SSI stuff also just for personal interest,
whether there is any easy possibility to get it working with current
version of SGE.
Cheers - Reuti
