EDGeS: Interconnecting Desktop and Service Grids
From Asia at Home
Abstract of the EDGeS talk
A Grid can be a powerful number crunching machine bringing the power of thousands of processors to an application developer's finger tips. Although current Grid infrastructures offer significant amount of resources to run computation and data intensive applications, some scenarios still overgrow the capabilities of existing Grids. Unfortunately, the two main types of Grids infrastructures, Service and Desktop Grid systems, were not interoperable until recently. The European EDGeS project is currently developing a bi-directional bridge connecting this diverse collection of resources. Desktop Grids will be compared to Service Grids, such as EGEE, and an introduction will be given into the EDGeS Grid infrastructure that connects both types of Grids with Bridges. The tutorial will explain what to do if you want to extend an EGEE VO with volunteer or local Desktop Grids or you want to connect your Desktop Grid to EGEE in order to get resources from EGEE.
Users of a grid infrastructure need tools and programming environments by which they easily can develop and run applications. The EDGeS consortium offers two different tools for programming desktop grid applications: DC-API and GenWrapper. The first one facilitates the creation of master/worker type applications while the second one enables the easy creation of parameter sweep applications based on legacy code applications. EDGeS also created a new advance version of P-GRADE portal called WS-PGRADE that enables the organization and execution of workflows in a transparent way automatically exploiting the various types of grids available in the EDGeS infrastructure. The talk will present and compare these tools and environments. It will illustrate their usage by several applications already ported to EDGeS.
