DIET
DIET is a software for grid-computing. As middleware, DIET sits between the operating system (which handles the details of the hardware) and the application software (which deals with the specific computational task at hand). DIET was created in 2000. It was designed for high-performance computing. It is currently developed by INRIA, École Normale Supérieure de Lyon, CNRS, Claude Bernard University Lyon 1, SysFera. It is open-source software released under the CeCILL license.
Like NetSolve/GridSolve and Ninf, DIET is compliant with the GridRPC standard from the Open Grid Forum.
The aim of the DIET project is to develop a set of tools to build computational servers. The distributed resources are managed in a transparent way through the middleware. It can work with workstations, clusters, Grids and clouds.
DIET is used to manage the Décrypthon Grid installed by IBM in six French universities (Bordeaux 1, Lille 1, Paris 6, ENS Lyon, Crihan in Rouen, Orsay).
Usually, GridRPC environments have five different components: clients that submit problems to servers, servers that solve the problems sent by clients, a database that contains information about software and hardware resources, a scheduler that chooses an appropriate server depending on the problem sent and the information contained in the database, and monitors that get information about the status of the computational resources.
DIET's architecture follows a different design. It is composed of:
Two approaches were developed:
For workflow management, DIET uses an additional entity called MA DAG. This entity can work in two modes: one in which it defines a complete scheduling of the workflow (ordering and mapping), and one in which it defines only an ordering for the workflow execution. Mapping is then done in the next step by the client, using the Master Agent to find the server where the workflow services should be run.
