Hi Mark,

As discussed...

IT/SciComp is ready for the Hall D data challenge. When we get your test
description details -- rates to/from tape, disk requirements, timeframe, etc,
we'll flip the farm nodes in HPC back to the farm, along with the 12s nodes
needed to get 2250 cores total in the cluster, so that Hall D will be able to
run 1250 cores with other jobs running.  The nodes to be moved from HPC will have
to drain jobs, which can take up to 48 hours.  We want to make sure you are
ready to run when we do it so that we don't waste CPUs sitting idle.

There's no SRM ability at JLab, and recall from the review that reviewers
suggested GlueX consider something besides SRM.  At one point in 2010 Curtis
had  firewall openings via our Cyber group for client tools installed
in user space on the ifarm nodes; check with Greg and company on that status
if still needed, as network configs for ifarms have undergone changed since then.

IT supports Globus Online for offsite data transfers using the site's 10 gigabit
pipe; info available at https://scicomp.jlab.org/docs/?q=node/11

Let us know when you're ready to run and what you need, then let the
node flipping and data challenge begin. I understand from today's discussion
you expect the timeframe to be sometime near the end of February.  Note that
the farm is currently almost idle at this point, so you shouldn't have any
trouble getting test jobs and prototypes started in the meantime.

Regards,
Sandy

9. Is the JLab CC ready for us?
+ Mark will talk to Sandy about our plans.
10. What ability will we have for SRM at Jefferson Lab?
+ Mark will talk to Sandy about the status of the system.
