<DIV style="FONT: 10pt arial"><B>Subject:</B> [torqueusers] cloning the
installation jobs for a generic LCG site</DIV>
<DIV><BR></DIV>Hi all,<BR><BR>I manage an LCG Grid site in Italy with about 15
HPC linux nodes,<BR>normally every node see the application software from a
<BR>NFS storage element and the application software is installed<BR>from
outside my site by someone that submit an 'installation job': <BR>when the job
arrive it runs on a node and it modifies the NFS area.<BR>I never know when
these jobs could arrive. <BR><BR>this is a terrible deployment strategy for me
because:<BR>1) you don't know when/where/why something change in your
cluster<BR>2) you can't check if something is changed after the
installation<BR> because you don't have a package manager, so you
don't know<BR> which is a correct status for the software (
permissions? crc? owner? size?)<BR>3) the NFS area is a single point of
failure<BR>4) the NFS area is a performance bottleneck for all the nodes:
there is not<BR> the concept of 'cache', so during the time the
nodes read many times<BR> the same files<BR>5) my nodes have hard
disks with a lot of storage not used: sure almost<BR> every node
can store all the application software ( that's about 90Gb )<BR>
without problems.<BR><BR>all the others Grid sites are designed in this
way!<BR><BR>for at least mitigate this scenario I want:<BR>1) Install the
application software everywhere it's possible: where it's <BR> not
possible continue to use NFS for now ( or AFS with a big cache? or what else?
)<BR>2) run tools like tripwire or samhain to understand when/where/why
something change <BR> on each node ( or what else? )<BR>3) the
most important point for Torque/Maui: run N copy of the installation job when
that arrives,<BR> one for each node that can store the application
software.<BR><BR>I well know the list of users that run the install job, they
are about 15:<BR>so how may solve this in Torque? do you have suggestions for
a better deployment design?<BR>I want more security and performances from my
cluster.<BR><BR>many thanks in advance,<BR>Fabio Martinelli<SPAN
