Hi Everyone,
We have an e-science farm which has its own front-end running a
PBS job manager and some worker nodes. I want our edg front-end to
pass job requests to the e-science front-end in much the same way
as the prescription described by Andrew Mcnab in reference to Babar.
The e-science farm has different home directories for different
applications e.g /home/hep, /home/astro and /home/edg
Now,
an edg worker node typically has mount points which look like
this:
hepbf4:/home /home
hepbf2:/flatfiles /flatfiles
hepbf4:/share/grid-security /share/grid-security
but an e-science worker node, configured to run edg jobs passed to it
from the e-science front-end would have mounts points like this:
hepbf4:/home /home/edg
hepbf2:/flatfiles /flatfiles
hepbf4:/share/grid-security /share/grid-security
Now lets assume that someone submits a job to our CE (hepbf4) and after
successful authentication the job gets mapped to $HOME/tutor01. Now on
the edg side $HOME is /home and the automatically created accounts are
visible, so no problem there. However, on the e-science side, $HOME is
also /home but no accounts are visible because the edg home directories
are mounted elsewhere! Clearly there will be a problem !!!
Perhaps there is a way in site-cfg.h to define a CE_HOME ???
Thanks, Dave.
