Portlets for Grid Computing

GEO Grid

The GEO (Global Earth Observation) Grid is an E-Infrastructure to accelerate GEO sciences based on the concept that whole data related to earth observation are virtually integrated with a certain access management and easy to handle by the endusers those are enabled by a set of Grid and Web service technologies.

Octave Gridtoolbox

The Gridtoolbox for GNU Octave provides an methods to access the Globus Toolkit grid middleware. Currently it focuses on data-transfer and authentication, so Octave could be used as backend for grid computing tasks.

java-simple-ca

Java Simple CAJava Simple CA is a pure Java web based Certificate Authority compatible with Globus simple CA, Linux and MS Windows. Why pay $600 a year for a SSL certificate from Verisign for your local network. Use Java CA from your web browser to create certificates and install them immediately in ... [More] your PCs! Java CA has the following features: Web browser interface Create certificate requests, sign certificates, and create self signed certificates A command line interface Compatible with Globus Simple CA, MS IIS and Linux (PEM encoded) Sign certificate requests from Globus, MS IIS or Linux to enable SSL in your local network Why pay for a Verisign certificate for your local network? Simple, open, extensible, and web based. This is Java Simple CA main web page: Here s a screen shot [Less]

Open PERMIS

PERMIS is an all-purpose authorisation decision-making engine with deployment packages for Apache and Globus Toolkit. OpenPERMIS is its offspring based on freely available libraries only.

GNDMS

The Generation N Data Management System (GNDMS) is a set of Globus Toolkit 4 WSRF services and associated tools for distributed grid data management based on staging and co-scheduling. It’s what you might want to use if you have big chunks of data that need to be copied around betwen supercomputer ... [More] centers in an orchestrated, and secure way. GNDMS abstracts from data sources via a data integration layer and provides logical names, data transfers via GridFTP, proper handling of GSI certificate delegation and workspace management. Besides data management functionality the implementation provides components for remote logging, run-time reconfiguration, persistence, and failover beyond what is available from Globus Toolkit.

migol

Especially for sciences the provision of massive parallel CPU capacity is one of the most attractive features of a Grid. In a distributed, inherently dynamic Grid fault tolerance represents a major challenge. The more resources and components involved, the more complicated and error-prone becomes ... [More] the system. In a Grid with potentially thousands of machines connected to each other the reliability of individual resources cannot be guaranteed. The benefit of the Grid is that in case of a failure an application may be migrated and restarted from a checkpoint file on another site. This approach requires a service infrastructure which handles the necessary activities transparently. In this article, we present Migol, a fault tolerant and self-healing Grid middleware for MPI applications. Migol is based on open standards and extends the services of the Globus Toolkit to support the fault tolerance of Grid applications. Further, the Migol framework itself is designed with special focus on fault tolerance. For example, Migol replicates critical services and uses a ring-based replication protocol to achieve data consistency. [Less]

wsrf4j2me

wsrf4j2me is an implementation of the Web Services Resource Framework (WSRF) for the Java 2 Microedition (J2ME). It is built on top of the ksoap2 API. It has been developed with the intent to allow direct access to Grid Web Services (see ... [More] http://globus.org/toolkit/docs/4.0/common/key/index.html#s-key-overview). The Web Services Resource Framework consists of the following Web Services specifications:  * WS-Resource  * WS-ResourceProperties  * WS-ResourceLifetime  * WS-ServiceGroup  * WS-BaseFaults In addition, WSRF builds upon:  * WS-Addressing  * WS-BaseNotification Currently, WS-ResourceProperties, WS-Addressing, WS-ResourceLifetime and WS-BaseFaults are fully or partially implemented. WS-ServiceGroup and WS-BaseNotification are not implemented at all so far. The project contains a sample J2ME application that shows how to use the API and interacts with the CounterService of Globus Toolkit 4. To my best knowledge, there is no freely available WSRF implementation for J2ME, thus I started implementing this one. It started as a school project and I currently do not have the time to finish it. However, the basics are laid out so that anyone seeking to implement WSRF for J2ME could use this as a basis. [Less]

srmlite

The goal of this project is to provide a very lightweight implementation of Storage Resource Management (SRM) interface for POSIX-compliant file systems that would be easy to maintain and deploy. Tool command language (Tcl) is used for implementing high-level logic and for gluing together several ... [More] technologies such as Grid Security Infrastructure (GSI), HTTP, XML and SOAP. [Less]
