Grids and Clouds

Did you say "grid & cloud" ?


Computing Grids are a form of distributed computing whereby a “super virtual computer” is composed of many networked loosely coupled computers acting together to perform very large tasks. Since 2000, the emergence of grids has revolutionized many services already offered by the internet because it offers rapid computation, large scale data storage and flexible collaboration by harnessing together the power of a large number of commodity computers or clusters of other basic machines. The grid was devised for use in scientific fields, such as particle physics and bioinformatics, where large volumes of data, or very rapid processing, or both, are necessary..

Cloud computing is a computing term or metaphor that evolved in the late 2000s, based on utility and consumption of computer resources. Cloud computing involves deploying groups of remote servers and software networks that allow different kinds of data sources be uploaded for real time processing to generate computing results without the need to store processed data on the cloud. Main cloud charactersitics include resources pooling and elasticity. According to the National Institute of Standards and Technology (NIST), Cloud computing means accessing shared and configurable computing resources, on-demand, through a broad network access.

France Grilles

France Grilles is a national (French) scientific interest group that gathers 8 partners (MESR, CNRS, INSERM, CEA, INRA, INRIA, RENATER, CPU). Infrastructures are distributed on many different production sites across the country. France Grilles represents France within the EGI european e-infrastructure, playing the role of the French NGI (National Grid Initiative).

Score Following

Development internship (may - august 2002)

INSA Lyon Computer Sciences Department
IRCAM Centre Pompidou Real time Systems


Nowadays, the development of so-called "mixed music" (instruments playing together with recorded music or electronic systems) is considerably growing within contemporary musical composing domain. However, one of the most blocking problems is the lack of adaptability during the performance, since it is quite difficult for a non-human system to really follow what the musician plays.

Score following is a concept that allows improving the quality of such performances: idea is to consider the electronic system as an accompanist rather than a guide, giving it the means to follow what the musician plays using a score recognition mecanism.

Realized work during this internship must be seen as a part of a wider research work handled by IRCAM - Real time systems team, and notably by Nicola Orio. This research work has lead to a Hidden Markov Models based score following system.

Virtual Music Teacher

Final year project (february - august 2003)

INSA Lyon Computer Sciences Department
Karlsruhe University Institute for Logic, complexity and deduction systems
IRCAM Centre Pompidou Real time Systems


One of the most important features of computers today is the way we can use them for education, learning and teaching.

The goal of this project is to define how we can teach music with a software, and to realize such one which allows computer aided music learning: with a score as reference, detect errors on played music, and give corresponding explanation (typical errors are for example wrong notes, rhythm errors, tempo errors, and interpretation errors).

Realized software should then allow music students to rehearse at home while noticing and correcting their errors.

That implies good definitions of errors and diagnostics rules, but that means too a searching work on interface problems: way to acquire and to model played music, output definition, etc.

In the current state of the art, the realized Hidden Markov Models based software allows to perform an error diagnosis on a monophonic MIDI piece.
