Work Package 1Installation and Evaluation of the
Globus Toolkit

• Massimo Sgaravatto
• INFN Padova

2
Objectives

• Goal evaluate the Globus toolkit as a GRID
  framework providing basic services
• Which services can be useful ?
• What is necessary to integrate/modify ?
• What is missing ?
• Duration 6 months (2000)
• Results of this first evaluation used to plan
  future activities

3
Tasks

• Globus deployment
• Security
• Information Service
• Resource Manager
• Data Access and Migration
• Fault Monitoring
• Execution Environment Management

4
Globus deployment

• Goal reduce complexity for installation and
  maintenance ? limiting the manpower
• Central Globus administrators responsible to
• implement and maintain a central software
  repository
• develop tools and documentation to enable local
  administrators to quasi-automatically install
  Globus on local resources

5
Security (GSI)

• Implementation of local Certification Authority
• Relations with other CAs
• Integration of existing applications with GSI
  authentication mechanisms

6
Information Service (GIS)

• Tests on performance and scalability
• Results used to define and implement the
  information service architecture
• Tools and interfaces for Grid users and
  administrators
• Integrate the default information with other
  info, provided by specific agents

7
Resource Management (GRAM)

• Job submission on remote resources that dont
  rely upon resource management systems
• Evaluation of GRAM with (local) resource
  management systems (LSF, Condor)
• RSL as uniform language to describe resources
• Translation from RSL to the specific resource
  description languages
• Cooperation between GRAM and GIS

8
Data Access and Migration

• Evaluation of GASS APIs to access remote files
• Adaptation of existing applications
• Evaluation of GASS and GSIFTP for data migration
  in LAN and WAN

9
Fault Monitoring (HBM)

• Evaluation of services for fault detection for
• Globus processes
• other system processes (i.e. http, ams, )
• user processes
• Data collectors
• Detect and notify about failures
• Recovery mechanisms (i.e. automatic restart of
  crashed processes)

10
Execution Environment Management (GEM)

• Evaluation of GEM as service for code migration
• staging of executable
• location and/or instantiation of runtime
  libraries

11
Deliverables Milestones

• Deliverables
• Tools, documentation and operational procedures
  for Globus deployment (6 Months)
• Final report on suitability of the Globus toolkit
  as basic Grid infrastructure (6 Months)
• Milestones
• Basic deployment grid infrastructure for the INFN
  GRID (6 months)
