Hi,
We just released first version of a new GIP plugin intended to replace
lcg-info-dynamic-pbs. This new plugin uses MAUI command 'diagnose' to
collect data about CE usage instead of Torque 'qstat'.
The reason for this new plugin is to be able to correctly publish CE
information when using advanced MAUI features like Standing Reservations
(this allow to reserve some job slots for certain types of jobs). With
lcg-info-dynamic-pbs, if you declare standing reservations, they appear as
free job slots even if they are not accesible by the queue. The new plugin
properly handle that. It could be extended in the future to support other
advanced MAUI features. This plugin should work properly even with a basic
MAUI configuration without any advanced features used.
Using this new plugin is pretty simple :
- Download RPM from
<http://quattorsrv.lal.in2p3.fr/packages/glite-3.0.0-i386/externals/lcg-info-dynamic-maui-1.1.0-2.noarch.rpm>
- Install RPM on your CE (it can coexist with lcg-info-dynamic-pbs)
- Edit /opt/lcg/var/gip/plugin/lcg-info-dynamic-ce to use the new plugin.
Command line should be (replace grid10... by your CE host name) :
/opt/lcg/libexec/lcg-info-dynamic-maui -l
/opt/lcg/var/gip/ldif/static-file-CE-pbs.ldif -h grid10.lal.in2p3.fr
- After checking everything is ok, you can uninstall lcg-info-dynamic-pbs
as the new plugin RPM advertizes lcg-info-dynamic-pbs feature and thus
satisfy CE_Torque metapackage dependencies.
If you are lucky enough to use Quattor (!!!), the new plugin will be put in
standard templates this week-end and you just need to define variable
GIP_CE_USE_MAUI as true in your cluster or site templates.
If you give it a try and have any problem, please contact plugin author,
Cédric Duprilot <[log in to unmask]>.
Cheers,
Michel
