Hi all, Based on the morning discussion, I've switched ByteIO and OGSA-data in the Thursday morning. There are two more the last minutes change requests we should discuss tomorrow; - Thursday afternoon Switch GRAAP joint session and Arch & Glossary 1.5 session, since Jim Pruyne will come mid afternoon. - Wednesday afternoon Move WS-management Profile discussion from Friday Morning to Wednesday afternoon and push naming session later. https://forge.gridforum.org/projects/ogsa-wg/document/2006Jan-OGSA-F2F-agend... Thanks, ---- Hiro Kishimoto Hiro Kishimoto wrote:

Hi all,

1) Early discussion (10 min) Note taker assignment Roll call Telecon minutes approval (Dec. 19) https://forge.gridforum.org/projects/ogsa-wg/document/minutes20051219/en/1 Agenda bashing

2) CDDLM-WG joint call (60 min) Jem has uploaded the revised version to the GridForge. - http://tinyurl.com/aez86 Look forward to proofread and tracker verification.

(1) Deployment and configuration section break-down

...

== Proposed list of sections ==

3.1 Provision (Deploy) an application on an existing BES container (The application can then be used to instantiate a BES activity. Mostly what is now 3.2 in EMS Architecture composition.)

3.2 Provision a BES container (What is now 3.1 in EMS Architecture composition)

[Both 3.1 and 3.2 assume that the 'level' of the BES container is pre-determined and fixed. See below.]

3.3 Using ACS do 3.1

3.4 Using ACS do 3.2

[Both 3.3 and 3.4 assume that the 'level' of the BES container is pre-determined and fixed. See below.]

3.5 Add time predictions to provision 3.1 and 3.2 by a deadline Using a deployment estimation service (perhaps based on historical data, etc, but how the estimation is done is out-of-scope.) Possibly requiring reservations.

[3.5 assumes that the 'level' of the BES container is pre-determined and fixed. See below.]

3.x Determine dynamically the optimal level of 'BES container' in the system and provision containers appropriately depending on workload etc may depend on analysis of the entire application CDL (down to hardware) for the entire workload of the system; use deployment time predictions; etc

(2) - Deployment versus provisioning requirements

...

(Or, where to 'cut' the CDL tree. Above the 'cut' point is deployment---assumed to be a relatively 'light' operation---and below is provisioning---assumed to be more heavy-weight.) - Deciding the cut point is orthogonal to CDDLM---it is policy or best practices and is therefore a system choice - Information (metadata) to help in making the choice could be added to the CDL as mark up - CDDLM implementations have walked the tree fairly far down (to the hardware) for deployment - CDL may be sufficient to express both deployment and provisioning. But it is an open issue if these two activities can, or should be unified in this way in OGSA. In particular CDL may not be going to the full extent of supporting costing, etc., that maybe needed to address all requirements - Resources beneath the cut point can be considered as pre-provisioned: they either exist or they don't. They are not going to be deployed themselves; but they can be used to deploy on. - Which resource to choose for deployment? It is the choice of the EMS architecture (EPS, CSG) and not of CDDLM. - Discussion on how CDL may be viewed as a hierarchy of scripts; and that one could have a history of costs associated with each node. In other words the tree could be decorated with other information (cost, etc, as metadata)

(3) - JSDL and CDL relation and can one cover the requirements for the

...

other - A JSDL submission may be associated with a deployment description or request, and the deployment portion could be described in CDL. [I.e., CDL could be a more specific application sub-type in a JSDL document.] - JSDL is not intended to describe the configuration of the software that will be used by the job. The aim is to describe things at a higher level. There may be similarities between the languages (perhaps around resource description) but it does not mean that one language can, or should, replace the other because they serve different purposes. - Jay wants to pursue the issue further among a smaller group of people.
