lecture BalticGrid Summer School
Date/Time: from Tuesday, 4 July 2006 (09:00) to Saturday, 8 July 2006 (18:00) (Europe/Zurich)
Chairperson:
Description: 
The BalticGrid Summer School comprises:

Day 1: Baltic Grid Presentations

Days 2-3: EGEE Tutorial

Day 4 Morning: Porting applications usig the P-GRADE portal and GEMLCA

Day 4 Afternoon: An introduction to Web Services

Day 5: Grid applications


IMPORTANT: The following requires preparation before the tutorial begins.

Participants in practicals during days 2-4 are invited to run their own applications. These should be able to be compiled on LINUX, should NOT be interactive (i.e. they should read input files and write output files). The code and data for these should be held in a tar ball, accessible for example by sftp. 


Location: in Tartu University, Estonia

EGEE Tutorial: Introduction to Grids and to EGEE (09:00 ->13:00 ) 
The purpose of this tutorial is to give a practical introduction to Grid Computing and the international EGEE grid.

The tutorial gives experience of the current middleware during practicals using the GILDA training testbed, as provided by INFN/University of Catania and partners.

This agenda may be subject to minor alteration.

Day 1 introduces the EGEE project and its middleware.

Day 2 has an application development focus - practicals are used to give experience of more advanced data and workload management.  In the afternoon participants will be invited to run their own applications.  These should be able to be compiled on LINUX, should NOT be interactive (i.e. they should read input files and write output files).  The code and data for these should be held in a tar ball, accessible for example by sftp. This requires preparation before the tutorial begins.

Introduction (15')    
 09:15
What is Grid Computing? (45')   transparencies powerpoint file pdf file    
 10:00
An overview of the EGEE project and middleware (30')   transparencies powerpoint file pdf file     
EGEE has established an international grid infrastructure. This talk describes the activities and objectives of EGEE.  It then outlines the major middleware services:
Authorisation and Authentication
Information Services
Data Managament
Workload management

These will be used during the practicals later in the day on the GILDA grid.

GILDA is a grid provided for training by the University of Catania and INFN, with partner sites in many countries.
 10:30
Authentication, Authorisation and Security (30')   transparencies powerpoint file pdf file     
The fundamental challenges of grid computing are described: how can trust be established between sites and users?? How can security be protected when communication is across a public network? How are users authorised to use computers and data?
11:00  COFFEE (15')

EGEE Tutorial: Practical introduction to the EGEE middleware (11:15 ->17:30 ) 
Using the GILDA testbed, participants will gain familiarity with the main services provided by the EGEE middleware. 

Following an overview of datamanagement,information systems and job submission, emphasis is upon how applications can be run on GILDA.
Chairperson:
 11:15
Using a certificate and simple job submission (1h0')   more information linkdown arrow   transparencies powerpoint filedown arrow pdf filedown arrow     
We will use the basic commands for certificate management and for workload management.
 12:15
Information systems on EGEE (45')   more information link   transparencies powerpoint file pdf file     
An outline is given of information systems.  The "BDII Information System" commands will be used to explore the GILDA grid.

Grid monitoring tools are used to display the current state of the GILDA and EGEE production grids.
13:00  LUNCH (1h0')
 14:00
Data management (1h30')   more information link   transparencies powerpoint file pdf file     
The management of files is described.   Commands are used to read, write, replicate and list files on GILDA's storage.
15:30  Tea (15')

Putting it all together! (45')   more information link   transparencies powerpoint file pdf file     
So far we have looked at the different services of the EGEE middleware.  Now we run some simple applications that show how to:
1. submit jobs that read/write files held on the Grid
2. use a script to submit jobs to run concurrently.
 16:30
MyProxy and Portals: using GENIUS on GILDA (45')   more information link   transparencies powerpoint file pdf file     
The MyProxy server stores and issues credentials.  One of its uses is to allow users to access grid services from a browser, through a portal.

In this practical MyProxy is introduced, and then the GENIUS portal on GILDA is used.

 14:00
Porting your applications to the GILDA grid (1h30')     
Participants are asked to bring their own code and data for this practical.

Programs should only take input from files and write output to files. (No interactive programs) They should compile on LINUX.

Porting applications to grids using the P-GRADE portal and GEMLCA (09:00 ->14:00 ) 
This morning continues the application focus, with an introduction to the P-GRADE portal and to GEMLCA which simplify porting applications to, and using applications on, a grid.  The examples brought by participants for day 2 of the EGEE tutorial will be used again with P-GRADE.
Chairperson:
 09:00
"Grid-enabling" applications using P-GRADE and GEMLCA (2h0')   transparencies powerpoint filedown arrow pdf filedown arrow   Gabor Kecskemeti (MTA-SZTAKI Laboratory of Parallel and Distrubuted Systems)   
The P-GRADE Portal is a generic, workflow-oriented graphical portal that can be connected to both LCG, gLite and Globus middleware based Grids. During the lecture and on-line demonstrations the following Portal capabilities will be introduced:

    * workflow development by a graphical tool
    * workflow execution in multiple grids
    * on-line observation and monitoring of workflows
    * data management

For more information about the P-GRADE Portal please visit www.lpds.sztaki.hu/pgportal
