grid computing
types
Parallel system
differences:Include a system in parallel compared to distributed system
Programmer view : one single machine executing parallel codes.
Various programming models (message passing, distributed
shared memory, data parallelism…)
Characteristics
Cluster computing
differences: it incluides a dedicated network over paralle system
Use of PCs interconnected by a (high performance) network as a parallel
(cheap) machine
§ Two main approaches
§ dedicated network (based on a high performance network : Myrinet, SCI, Fiber
Channel...)
§ non-dedicated network (based on a (good) LAN)
Characteristics
differences: Distibuted system interconected
Traditional programmer view : client-server
User view : one single (virtual) system
an interconnection network
Characteristics
Meta-computing
differences: it's a not a loose coupled cluster computing
Definitions become fuzzy...
§ A meta computer = set of (widely)
distributed (high performance)
processing resources that can be
associated for processing a parallel
not so loosely coupled code
§ A meta computer = parallel
virtual machine over a
distributed system
Characteristics
Grid computing
differences:a group of clousters computing
Information grid : large access to distributed data : the Web
§ Data grid : management and processing of very large distributed data sets
§ Computing grid ~ meta computer
§ Ex : Globus, Legion
Characteristics
Peer to peer
differences:dedicated equipments known as a client and sever to offer a service
§ A site is both client and server : servent
§ Dynamic servent discovery by « contamination »
§ 2 approaches :
§ centralized management : Napster
§ distributed management : Gnutella, Kazaa
§ Application : file sharing
Characteristics
Global computing
differences:A extended meta-computing with poor comunication
ternet computing on a pool of sites
§ Meta computing with loosely coupled codes
§ Grid computing with poor communication facilities
§ Ex : Condor
Characteristics
Internet Computing
differences: A grid computing system dedicated for a single proporse
Information grid : large access to distributed data : the Web
§ Data grid : management and processing of very large distributed data sets
§ Computing grid ~ meta computer
§ Ex : Globus, Legion
Characteristics
Network computing
differences: it's a WAN-MAN cluster computing with a loose coupled codes
From LAN (cluster) computing to WAN computing
§ Set of machines distributed over a MAN/WAN that are used to execute parallel
loosely coupled codes
§ Depending on the infrastructure (soft and hard), network computing is derived
in Internet computing, P2P, Grid computing, etc
