West Team: High Performance Computing

Gaspard2 v1.0.0 is available.
TrML v0.1.0 will be soon available.

Co-modeling for SoC Design at the University of Lille 1

The West Team is a research team of the LIFL (Laboratoire d'Informatique Fondamentale de Lille, the computer science lab of the University of Lille 1).

The LIFL is build around three main research groups. The West Team is member of the SCOPE Research Group which deals with parallelism, distributed computing and optimization.

DaRT INRIA Project

Our team is member of the INRIA LILLE - NORD EUROPE Research Unit as the DaRT project.

Our activity report for 2007 is available.

Research Themes

Our team's research interests fall in the area of parallel computing with emphasis on the data-parallel model. We mainly focus on intensive signal processing applications.

Our main projects, as shown in the DaRT proposal concern the modeling of intensive signal processing applications and their execution architecture, the mapping and compilation of these applications and the study of real-time operating systems for SMP computers.

Modeling
We promote the use of UML and MOF to model intensive signal processing applications, heterogeneous embedded architectures (such as Systems-on-Chip) and the mapping of these applications on these architecture. This figure presents the organization of our approach.
Mapping and compilation
Based on our previous works, we aim at developing an unified space-time mapping methodology for our particular case. The targets of our compilations include heterogeneous distributed simulations (using tools such as CORBA and SystemC).
Real-time OS for SMP
We propose an asymmetric scheduler for Linux on SMP computers (see the ARTiS project below).

These three main areas form the core of our projects but we keep a few actions related to our previous focus on the design of an environment for the scientific programming of parallel/distributed architectures; WEST initially stands for "Workstation Environment for SupercompuTing". This study concerns the definition, the simulation, the validation and the implementation of concepts promoting the data-parallel model. We are particularly interested in the dynamic and irregular issues of the data-parallel model. Many of our works also emphasize the graphical/visual aspect of data-parallel programming tools.

Based on these works, we also develop applications: 3-D discrete event simulation in electromagnetism, parallel Montè Carlo methods for semiconductors simulation...

Research Actions

The team is currently working on the following subjects:
