Two Stories about Love : the Geometry of Distributed Systems
par Sergio Rajsbaum (Professor University of Mexico)



Distributed computing encompasses a wide range of systems and models.

At one extreme, there are tiny graphical processing units and specialized devices,
in which large arrays of simple processors work in lock-step.

In the middle, desktops and servers contain several multithreaded, multicore processors, which use shared memory communication to work on common tasks.

At the other extreme, cloud computing and peer-to-peer systems may encompass thousands of machines that span every continent. These systems appear to have little in common besides the concern with complexity, failures and timing.

Yet, they aim of this talk is to reveal the astonishing fact that they do have much in common, and what they have in common is that computing in a distributed system is essentially a form of stretching one geometric object to make it fit into another in a way determined by the problem.

Two simple stories will be used to illustrate that topology provides the common framework that explains essential properties of these models.



Sergio Rajsbaum, professeur à l'UNAM, est l'un des fondateurs de la théorie mathématique de la calculabilité distribuée. Cet exposé à visée grand public présentera la formalisation des systèmes répartis à partir de plusieurs exemples.
Sergio Rajsbaum est professeur invité par la FCS STAE au LAAS-CNRS.
