3 About Grid Computing -The term Grid computing emerge in the early 1990’s. - Originally it was a metaphor for making computer power as easy as an electric power grid. - First appearance in Ian Foster & Carl Kesselmans work: "The Grid: Blueprint for a new computing infrastructure". -This grid computing idea was created by Ian Foster, Carl Kesselman and Steve Tuecke, regarded as the "fathers of the grid”. -Goal: create “Globus Toolkit” which include computation and storage management. -Utilization : -Used to denote a hardware and software infrastructure that enables applying the resources of many computers to a single problem. -Used to denote a hardware and software infrastructure that enables coordinated resource sharing within organizations.

4 About Grid Computing (cont) Definition: Using resources of many separated computers connected by a network to solve large-scale computation problems that requires a great number of computer processing cycles or access to a large amount of data. Projects examples: LCG – Petabytes of data will be recorded and analyzed every year. ‘ SETI – (Search for Extraterrestrial Intelligence) @Home project in which thousands of people are sharing the unused processor cycles of their PCs in the vast search for signs of "rational" signals from outer space.

5 About CompuNet -CompuNet is an implementation of the “grid computing” idea in.Net with extensions for generic projects. -This application enables simultaneous running several.Net computation projects in parallel, utilizing the power of all the clients connected to the CompuNet grid.

6 Implementation steps Project requirements Use-case diagram and specifications Class and Package diagrams Sequence diagram Scheduling Coding Testing and bug fixing Documentation (presentation, project book)

7 Technologies.Net Remoting –Allows an application to make an object available across remoting boundaries, which includes different appdomains, processes or even different computers connected by a network. –In CompuNet, we use.Net Remoting to send messages between CompuNet actors (service, management and client), stealing the idea of post office. XML Serialization –Process of packaging data structures or saving an object in a format that can be easily transported. This format is an xml file. –In CompuNet, we use XML serialization to save client and management GUI configuration settings and server database and reports

8 Technologies (cont) Reflection –Reflection can be used to dynamically create an instance of a type, bind the type to an existing object, or get the type from an existing object and invoke its methods or access its fields and properties. –In CompuNet, we use Reflection to run small work units (chunks) on clients Windows Installer –Windows Installer enables customers to provide better corporate deployment, and provide a standard format for component management. –In CompuNet, we implemented Installer using Visual Studio 2005 Setup Project. It can install either client or server or both.

9 CompuNet terms Job – big computation project divided into computing units (chunks). Chunk – single computing unit that will be sent to the client computer to be processed. Chunk result – computed value that is either used by dependant chunks or shown as a final result, also known as Job Result Server – responsible for jobs and clients management and chunks distribution. Client – a computer registered within the system to run job’s single computing unit (chunk). Chunk dependency – chunk can be dependant or independent: Independent – no inputs, runs when the job starts. Dependant – the chunk depend on the output of other chunks, when all the input is collected. c1 c2c3 c4 job1

10 System overview

11 Object-oriented Analysis and Design Package Diagram Client Module CompuNet Core Server Module

12 Object-oriented Analysis and Design CompuNet Core Module CompuNetCore –Holds the definitions of Job, Chunk, Client and other basic classes of CompuNet CompuNetRemoting –Allows sending messages between CompuNet actors over TCP Remoting CompuNetResources –Holds icons used by all the components

13 Object-oriented Analysis and Design Client Module GUI and Tray Icon –Allows the client to choose the server address and see which chunk is running now Chunk Runner –Runs the chunk sent by the server

14 Object-oriented Analysis and Design Server Module Main Service module –Holds server database that includes jobs and clients information –Distributes the chunks between clients Management GUI –Shows the server status –Shows the jobs, their status and results and allows adding, starting, stopping and reporting the job –Shows the information about registered clients

15 CompuNet Usage

16 Job example Chunks dependency: c1 c2c3 c4

17 Job xml file:

18 Possible extensions and improvements GUI for Project Creation –Now, user needs to create and edit XML file Improve GUI of Project Monitoring to show chunks as directed graph Support chunks running in long loops –clients will get only range of loop and server will combine the result –no need to define lots of chunks Compile code on client –User adds chunks as formulas, client compiles the code and runs it

19 Thank you!

20 CompuNet Server Database Server Database: -Jobs  Chunks  Credentials (Name)  Status  Vertices -Jobs in process -Clients  Client information  Current chunk information -Free clients -Busy clients

21 CompuNet Client information Client information: - Nickname - Client status - Configuration - Server address - Preferred jobs - Current chunk - Current job name
