I am not arguing for adding more levels to the scheduling decisions,
but was merely pointing out to Mats that we have been bypassing the
main schedulers of various systems for a while now, and that the reason
for not following through with installing WS-GRAM should not be because
of this. In fact, I don't support the idea of installing a user level
GRAM per site. Its not even clear to me, how you would make that happen
in a generic way, as GRAM needs to be configured to be used in
conjunction with other LRMs, SGE, PBS, Condor, etc... so you not only
need to install GRAM, but also configure it against another LRM, that
you might know little about where its installed, the paths to the
various logs (which GRAM needs), etc. If Coaster can be made to run
transparently and works well enough for production, then Coaster can
run on top of GRAM2 just fine, as the load it will impose on GRAM is
lower than what the same app would impose if it were to go directly to
GRAM. <br>

I suppose too much multi unnecessarily complicates things.</blockquote>
