27-29 September 2002 CrossGrid Workshop Meeting @ LINZ 2

Introduction

• For this task we can distinguish two scenarios:– Use Case for the

WP3 Integration Team

– Use Case for WP3 users (most likely from WP4)

Task 3.5 (WP3) Integration Team:

-Pawel Wolniewicz (PSNC, Task3.1)-Miquel A. Senar (UAB, Task 3.2)-Bartek Balis (CYFRONET, Task 3.3)-Slawek Zielinski (CYFRONET, Task 3.3)-Lukasz Dutka (CYFRONET, Task 3.4)-Álvaro Fernández (CSIC, Task 3.2)-Javier Sánchez (CSIC, Task 3.5)-Santiago González (CSIC, Task 3.5)

More people are welcome!!

27-29 September 2002 CrossGrid Workshop Meeting @ LINZ 3

1st Use Case for the WP3 IT

• Prerequisites:Prerequisites:– Deliverables from each software task is expected in

Month 10-11. Each partner should test well its own software before releasing the code to Integration Team.

– All members of the IT should be physically in the same place (Karlsruhe).

– Resources needed for the intensive Integration phase: hardware required for a CrossGrid Testbed.

27-29 September 2002 CrossGrid Workshop Meeting @ LINZ 4

Use Case for the WP3 IT• Test and Integration phase:Test and Integration phase:

– WP3 IT will obtain the software from the CVS server.– Test the WP3 software.

• Integration Team is composed by a member from each task and partner• Each task must provide its services and tools with detailed information about

installation, test and functionality.

– Integrate and test the WP3 software in a Real CrossGrid testbed.– Once everything functions, the distribution packages (RPM’s, tar.gz, etc)

should be made. Installation from these distribution packages must be verified.

– Provide these packages to a central HTTP repository or a central Web site.– The WP3 IT should fully document the installation process and prepare the

Installation Guide.

27-29 September 2002 CrossGrid Workshop Meeting @ LINZ 5

2sd Use Case for WP3 Users (WP4)

• Prerequisites:Prerequisites:– Red Hat Linux 6.2 (Test platform supported for first

prototype 1).– RPM’s for Testbed 1 created RPMv3 (used by

DataGrid).– Local resource management (Batch system).

• PBS, LSF and “Condor” supported by DataGrid.– Request host and user certificates.

Have a CrossGridTestbed(WP4)

27-29 September 2002 CrossGrid Workshop Meeting @ LINZ 6

Use Case for WP3 Users (WP4)

• Obtaining WP3 software:Obtaining WP3 software:– Read Installation Guide done by WP3 Integration Team

– Obtain packages from package repositories (HTTP repository or Web central site) in Karlsruhe (DataGrid uses RPM files and marianne).

– Install the packages (DataGrid uses RPM tools).

– Modify the configuration files and run the programmes using the Installation Guide.

– “Start” and/or “Stop” the corresponding Daemons related with the packages (for example, /etc/rc.d/init.d).

Partner Actions in next weeks(Task 3.5 Test and Integration)

27-29 September 2002 CrossGrid Workshop Meeting @ LINZ 8

Introduction• After M6 (NOW) WP3 will start to develop

prototypes of the tool and new grid services.– See Design document produced in M6.

• The four partners of this task will test all tools and services (precising interfaces and functionality).

• The goal is to be able to deliver a middleware layer in the CrossGrid testbed.– Important define and understand at Linz what we

may expect as 1st prototype!!!

27-29 September 2002 CrossGrid Workshop Meeting @ LINZ 9

Todo list by each Partner• Before Month 10-11:Before Month 10-11:

– After defining (M3) and designing (M6) the architecture of the new grid services and tools, each partner has to make and test well its software according to test procedures proposed by each Task (see D3.2).

• Compatibility between WP3 software, Globus and EDG software will be guaranteed. Vital evaluation with consequence serious for the success of the integration phase.

– Each task must provide its services and tools with detailed information about installation, test and functionality before releasing the code to the WP3 IT.

• How each task will release its products to WP3 IT?:– Obtain the software from the CVS server– Synchronisation within tasks– What kind of files will be used (RPM, tar.gz, etc…)

27-29 September 2002 CrossGrid Workshop Meeting @ LINZ 10

Todo list by each Partner

• Before Month 10-11:Before Month 10-11:– Co-ordination with WP4 and its time

scheduling.• We need a real CrossGrid Testbed to test and

integrate our WP3 products.

27-29 September 2002 CrossGrid Workshop Meeting @ LINZ 11

Todo list by each Partner• After Month 10-11:After Month 10-11:

– Integration-test phase.• All WP3 IT members should be physically in

Karlsruhe together to WP4 integration team people.– At Karlsruhe we have the hardware required for a real

CrossGrid testbed and the central CVS server.

• Test WP3 software before installing to the Testbed.– WP3 IT is composed by a member from each partner and

task: “We have an expert for each WP3 service or tool!!!”

• Integrate and test the whole WP3 software and once everything is working, the packages will be distributed (RPM, tar.gz, etc..)

27-29 September 2002 CrossGrid Workshop Meeting @ LINZ 12

Todo list by each Partner

• After Month 10-11:After Month 10-11:• Provide these packages to a central HTTP repository

or a central WEB site. Documentation about installation process (Installation Guide) will be prepared.

– Important define where will be the HTTP Repository or central Web site!!!! (Poznan, Karlsruhe, …)

27-29 September 2002 CrossGrid Workshop Meeting @ LINZ 13

Partners and IT responsibilities

• IT has to follow the progress of each task:– The software should be available to IT to the end of

Month 10 (We need one month to do the integration!!!).

– Each task has to write a document with detailed information about installation, test and functionality (This will help to prepare the WP3 Installation Guide)

• IT members have to be available in Month 10-11 to produce and deliver first release version of WP3 software (Installation from this release version in a real CrossGrid testbed must be verified) .

27-29 September 2002 CrossGrid Workshop Meeting @ LINZ 14

Partners and IT responsibilities

• Collaboration with WP4 IT is required.– Participating in WP4 IT meeting and follow the

Testbed evolutions (Next meeting at CERN together EDG IT, 30th October 2002).

27-29 September 2002 CrossGrid Workshop Meeting @ LINZ 15

Task 3.5 Agenda

• Goal: Have a better understand about the Integration-Test phase and define it more precisely:– Use cases discussion (All the points are a

proposal and I would be very grateful for your comments and suggestions).

– Partner Actions and Responsibilities in next week.

– Integration Team Actions and co-ordination
