Hi Everyone -<br>
<br>
at present, the only method "reasonable" method to get data out of
JLab is to <br>
use bbftp. While this works, it is a lot of user overhead to make
things work. As<br>
noted during the meeting, the lab used to have the srm tools. These
were a lot<br>
better than bbftp, but due to changes in computing at JLab, and
probably lack<br>
of regular use by users, this tool has vanished.<br>
<br>
I think that in any model, data will be processed at JLab.
Presumably, we will<br>
also run some "high-level" skims at Jefferson Lab which will then be
exported <br>
to outside clusters. Having the capability to manage this export with
grid tools<br>
is important. <br>
<br>
We also have our Monte Carlo needs which under our current model are
most<br>
likely generated offsite. The ability to move these results is also
crucial. We need<br>
to make sure that our needs are made clear, and apparently need to
spell it all<br>
out carefully.<br>
<br>
curtis<br>
on the grid. This is likely to continue <br>

One thing stands out to me in reading through this plan is the lack of
any accommodation for the interaction between the Jlab computer center
and computing facilities at user institutions. For comparison, it is
helpful to look at the computing plan for any of the LHC experiments,
where the plan is oriented around distribution and global access to
data and computing resources. Things that I would like to see in the
Gluex Offline Computing Plan that eventually get propagated through
appropriate channels to someone like Graham Hayes are the following:<br>
<ol>
<li>Location-independent mechanisms for remote access to MSS files
(with appropriate authentication/authorization) without logging in on a
Jlab machine over ssh, both reading and writing.</li>
<li>Provision for allocation of space on MSS for archival of
intermediate data sets generated off-site, eg. MonteCarlo and final
data samples used in a PWA that was the basis of a particular
publication.</li>
<li>Support of grid protocols for transparent scheduling and
migration of jobs across available resources within the collaboration,
so that when a particular resource is overbooked jobs can flow across
site boundaries to where resources are available.</li>
</ol>

<pre wrap="">Folks,
I've just posted a document from Graham Heyes, describing the Lab's
scientific computing plan for the current fiscal year. It is
GlueX-doc-1530. The document page is
<a moz-do-not-send="true"
href="http://argus.phys.uregina.ca/cgi-bin/private/DocDB/ShowDocument?docid=1530">http://argus.phys.uregina.ca/cgi-bin/private/DocDB/ShowDocument?docid=1530</a>
I've posted it on our DocDB not because it is GlueX-specific (it is not)
but just so we have a well-defined place to find it and to reference it.
