Review of the Community Uptake of the Application Hosting Environment Grid Interface
Key to broadening participation in grid computing is the provision of easy to use access mechanisms and user interfaces, to allow a wide range of users with different skill sets to access the computational and data resources on offer. The Application Hosting Environment is one such middleware tool, hiding much of the complexity of dealing with grid resources from the user, and allowing them to interact with applications rather than machines. The nature of AHE means that it can be used as a single interface to a wide variety of resources, ranging from those provided at a departmental or institutional level to international federated grids of supercomputers. The AHE has users in a number of academic institutions in the UK and beyond, mostly using it to run simulations on resource such as the UK’s National Grid Service, including the high end machine HECToR and also on the US TeraGrid and EU DEISA grid. In addition a number of groups and projects worldwide are either deploying or evaluating the AHE. These groups include both scientific projects looking to deploy one or two applications for use by project members and grid resource providers aiming to host a number of different applications for use by a wide community. In this white paper we will give a brief overview of the Application Hosting Environment software, and then look at several case studies of groups and projects that are currently making use of AHE.
