Alchemi API: Grid Thread Programming Model(1/4)

Grid Thread Model– Deal with application, thread objects and any

custom objects– Without worrying about “plumbing”– Use API with C#, VB.NET, Managed C++...etc.

Grid Job Model– Grid-enabling existing applications– Cross-platform interoperability with grid middl

eware

Performance Evaluation(1/6)

Standalone Alchemi Grid– Pentium III 1.7GHz+512MB+Windows 2000– PC*6 and one as a Manager– Calculating 1000, 1200, 1400, 1600, 1800, 20

00 and 2200 digits of Pi– Each thread calculate 50 digits

Summary and Future Work(1/2)

Summary– Alchemi is an easy-to-use Enterprise Grid

framework– Offers a simple way to get up and running

with a Windows-based compute Grid– Has a flexible programming model and simple

tools for monitoring and administration

Summary and Future Work(2/2)

Future work– Inter-thread communication (MPI-like or .NET

remoting-based)– Multi-clustering / federation (for

decentralization and improving scalability)– Economy scheduling– Web-based tools for monitoring/admin– Workflow and other application models– Data-centric features
