Résumé

We present the Intelligent Application Oriented System (IANOS) resource broker models and internals. The aim of IANOS is to provide an understanding of and a solution to the problem of how to find the best resource for a given submitted application in order to optimally use a set of HPC resources (an HPCN Grid). Best in the sense “at a given moment and for the requirements of that specific application”. The heart of IANOS is a cost model that minimizes the overall submission cost such as execution time cost, waiting time cost, licenses cost, energy cost, etc. To estimate the execution time cost, a model predicting the performance of an application on a resource where INAOS is installed is provided. This model is based on a parameterization of the application and the resources. IANOS has been deployed and tested successfully on an international testbed across Switzerland and Germany.

Predictive modelling

Predictive modelling uses statistics to predict outcomes. Most often the event one wants to predict is in the future, but predictive modelling can be applied to any type of unknown event, regardless of when it occurred. For example, predictive models are often used to detect crimes and identify suspects, after the crime has taken place. In many cases, the model is chosen on the basis of detection theory to try to guess the probability of an outcome given a set amount of input data, for example given an email determining how likely that it is spam.

Resource

Resource refers to all the materials available in our environment which are technologically accessible, economically feasible and culturally sustainable and help us to satisfy our needs and wants. Resources can broadly be classified upon their availability — they are classified into renewable and non-renewable resources. They can also be classified as actual and potential on the basis of the level of development and use, on the basis of origin they can be classified as biotic and abiotic, and on the basis of their distribution, as ubiquitous and localised (private, community-owned, national and international resources).

Serveur d'applications

vignette|Logo symbolisant une application serveur Un serveur d'applications est un logiciel d'infrastructure offrant un contexte d'exécution pour des composants applicatifs. Le terme est apparu dans le domaine des applications web. Au sens strict les composants hébergés par le serveur d'applications ne sont pas de simples procédures ou scripts mais de réels composants logiciels conformes à un modèle de composants (EJB, COM, Fractal, etc.). Les clients des serveurs d'application sont : des programmes autonomes (standalone application), des applets ou d'autres composants.
