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) • 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) Deploy Grid in Israel Universities
Classes of parallel computing Supported by Grid Deploy Grid in Israel Universities
Assumptions • Grid should be functional • Users are scientists • Prefer open source • Run on Linux RedHat 7.3 Deploy Grid in Israel Universities
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 Deploy Grid in Israel Universities
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 Deploy Grid in Israel Universities
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 Deploy Grid in Israel Universities
