Hi....
Sorry for coming late to this thread. I just want to add the following
on this point:
At LIP, for example, we do not use shared file systems for the SGE
instalation dir nor for the home directories. This is also the approach
assumed in the proposed gLite integration. SGE can work like this just
enabling scp mechanisms to transfer files. The drawback is that you lose
high availability because in that way you can not set a shadow qmaster
server host that assumes control if the primary qmaster server host
gives you some problems.
Cheers
