GECOS : Mécanisme de synchronisation passant à l'échelle à plusieurs lecteurs et un écrivain pour structures chaînées.

This paper presents GECOS (GEneration Counter Optimistic Synchronisation), a new mechanism for a multi-reader single-writer lock-free access to linked data structures. This mechanism has been specially conceived to take into account different constraints of manycore architectures by ensuring not only scalable performance, but also an optimal use of memory. First results, obtained on a system with 64 cores, show excellent performance that are similar to the best known mechanisms, such as Hazard Pointers or Read-Copy-Update. [ABSTRACT FROM AUTHOR]
