Hi,
I agree with Marty’s comment.
(Sorry I missed the telecon, my day job
got in the way; I know I still owe our experience for the experience doc).
Best regards,

Re: “file
staging”.
I think the approach
that multiple active participants of the group are currently pursuing (see
Steven’s most recent thread) is the appropriate approach, given the scope
and intent of this WG. We made good progress in Supercomputing 2007 –
both refining and validating the approach. I believe that this is a good plan.

This should be an interesting phone call.
Let me go through these and add comments,
then a few of my own.
File staging. Yes. But before we can do a
good job on staging we need a solution to the delegation problem. As I said in
Kerberos credentials. See my comment
above. Or possibly I don’t know what in this case is meant by Kerberos
credentials? For what? Presumably for the activity to execute with those
credentials. Then why just Kerberos?
Application inventory. An interesting
idea, maybe just need to define a set of qnames. Let me suggest an alternative
that we have developed and have working here at UVA. An application description
and deployment service that is far far simpler than CDDLM. (Works with zip
files) Handles 98% of the HTC usecases we have encountered very easily –
and offers the ability to define an application as the application and a set of
data files … meaning they don’t get copied every time.
Machine inventory. The BES specficiation
has something for this that was the result of much discussion between GLUE
folks, CIM, etc.
Resource usage data! I’m all for
this, can we just use RUS?

Extensions Short-list
Hi,
I had occasion to have coffee with Chris Smith today, and we
discussed what we think would be the most useful near-term extensions to the
HPCBP.
Turns out our list is pretty short (in no particular order):
File staging (already in process)
Kerberos credentials (with Active
Directory support)
Application inventory (a simple list
of available applications, maybe leveraging the Glue Scheme work)
Machine inventory (a list of
hardware: hosts, cpus, memory, etc, as well as what’s in use and
what’s free; maybe also leveraging the Glue Scheme)
Resource usage data (for simple accounting
and status reporting)
Anyone else interested in any of these areas? Anyone
interested enough to work on drafting an extension?
Best regards,
- bill
