[ogsa-hpcp-wg] HPCBP Extensions Short-list

[Bill Nitzberg]

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.

 

Phone call in 7 minutes.

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 Seattle I am unhappy with the solution
of an extra parameter to the call. Can we not come up with a solution that might
be useable for other services as well, e.g., somewhere in the soap header?

 

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?

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
