The grid problem l.jpg
The Grid Problem

  • Seamless, flexible, secure, coordinatedresource sharing among dynamic collections of individuals, institutions, and resources

  • Enable virtual organizations (VO)s to share geographically distributed resources as they pursue common goals assuming the absence of:

    central location, central control, trust relationships.

The grid is not yet l.jpg
The Grid is NOT (yet)

  • Not: Super computing

    • The trend: Many PCs rather than a big computer

  • Not: Can not guarantee fastresponse, mainly because of network limitations

  • Not (yet) : A total solution for distributed computing

    • Batch rather than interactive or stream oriented:Examples: the grid is not geared to

      • Support games

      • Show a lecture on line

  • Not (yet) : Ultimate parallel computing solution

    • Supported class: Embarrassingly Distributed (ED)

Assumptions l.jpg
Assumptions

  • Grid should be functional

  • Users are scientists

  • Prefer open source

  • Run on Linux RedHat 7.3

Slide11 l.jpg
How?

  • Define priorities for required functionality and suppliers of relevant SW packages

  • Support wide functionality scope. Each institution will select its subset

  • Find best, up-to-date, reasonably tested, set of SW packages

  • Honor Glue - USA-Europe collaboration

  • The actual content and versions will change because SW is evolving

  • Stick to one SW provider that does exactly that

Lhc computing grid lcg l.jpg
LHC Computing Grid - LCG

  • LCG is the project that selects at tests computing grid SW for LHC experiments in CERN

  • LCG will supply highly integrated Grid SW

  • Utilizes American and European Grid SW

  • Honors GLUE: America-Europe collaboration

Lcg main sw suppliers l.jpg
LCG main SW suppliers

  • Globus: A bag of Grid services

    • GSI: Grid Security Infrastructure

    • GRAM: Grid Resource Allocation & Management

    • MDS: Monitoring and Discovery Service

    • GridFTP: file transfer over the net

  • VDT:

    • Condor-G: Submit jobs and monitor job consistency

  • EDG:

    • Resource Broker: Select on what Computing Element (CE) to submit job

    • Data replication

    • VOMS: Virtual Organization Management System

    • TBD: LCFG: Installation and configuration

  • GLUE:

    • Make sure that USA and Europe grid SW work together
