A couple of days ago you made a post re. updating mechanisms, where
you talked about yum, or yum-like mechanisms which would recompile
packages to suit the target node, or something along those lines.
How about we think of applications along the same lines - but not
necessarily being recompiled.
In the context of a grid world, it still worries me that people are
saying that application Z will run anywhere - on some machine maintained
on another campus - who knows if it is even running the same Linux
distribution? (OK - maybe everything needs to be statically linked then.)
If I may, I'll join Bob in a blue sky thought. How about applications
being installed as RPMs? Then the RPM would have dependencies -
application Z needs library-b between x and y.
Could you then get a message back saying 'sorry - this cluster won't
support this application: it needs x-y'
Sorry - a huge bly sky here. But we do keep hearing about grid and
infrastructure on demand.
