Open Source Grid Middleware Packages

The document discusses open source grid middleware packages. It describes how grid middleware lies between grid hardware and software, providing services like remote process management, storage allocation, resource allocation, and security. It then summarizes several popular open source middleware packages: BIONIC was developed for the SETI@HOME project; UNICORN provides a Java-based integrated grid computing environment; GLOBUS is a widely used toolkit developed by the Globus Alliance; and Condor-G builds a high-throughput computing environment from Condor.

Open Source Grid Middleware Packages By Shivaram B
Grid Middleware Packages ● Grid Middleware lies between grid hardware and software which provide different services like ❏ Remote process management ❏ Storage allocation and access ❏ Resources allocation ❏ Resource reservation ❏ Security ❏ Quality of services
Grid system includes ➔ Computational resources ➔ Storage resources ➔ Network resources ➔ Scientific instruments Grid middleware is a software which provides users with ➔ Access to resources ➔ Computing ability
Application Layer ==>This layer deals with running grid application or portals built using grid enabled languages like ● MPI(Message Passing Interface) ● HPC(High-Performance C++) ==>The grid web portals offer web enabled services through which user can submit their job to grid or collect their result from the grid.
Development and deployment layer ➔ This layer allows user to develop and deploy grid application over grid infrastructure and uses low level middleware interfaces to provide higher level abstrated services. ➔ The applications of this layer are to provide application development environment programming tools, resource brokers for managing the resources and handle job scheduling.
Core Middleware layers This layer deals with providing essential services to grid hardware and software includes ➢ Remote process Management ➢ Resource management ➢ Storage management ➢ Information registration ➢ Discovery Services ➢ Security Services ➢ Job scheduling services
Grid Fabric and hardware ❖ This layer composed of distributed resources like computers, network devices, storage devices and scientific instruments. ❖ The computer resources represents cluster, supercomputers which run different Operating System while Scientific instruments like sensors networks, wireless devices provides real time data computational sites.
Open Source Middleware Package ● BIONIC ● UNICORN ● GLOBUS (GT4) ● CONDOR - G
BIONIC(Berkeley Open Infrastructure for Network Computing) It is an open source middleware originally develop to manage SETI@HOME Grid project. The SETI@HOME is a scientific experiment that uses internet-connected computers in the search for Extraterrestrial Intelligence (SETI). It was developed by University of California,Berkeley. UNICON(Uniform Interface to Computing Resources) Integrated Java based grid computing environment that provides a seamless and secure access to distributed resources. It was developed by German Ministry for Research.
GLOBUS Open source software toolkit and libraries that facilitates construction of computational grids and grid based applications. It was developed by “Globus Alliance” which includes Argonne National Laboratory, Information Sciences Institute and others. Condor-G Condor is a software system that creates a High Throughput Computing (HTC) environment. Sun grid Provides High-Performance Computing Clusters (HPC) for accepting, scheduling, dispatching, and managing the users jobs over distributed infrastructure.
