Dear All, Following the on-going efforts on development and standardization of C++, especially application-oriented libraries, we are soliciting expression of interest within the C++ community for a new Boost library for building Discrete-Event simulators. We plan to build this new library on the latest features of the C++11 standard, for possible inclusion in a future version of the C++ standard. This work is based on our experience in building C++-based simulators for over 20 years, exploring various optimization and algorithms, and leading to a significant number of reseach publications. Writing a new version of a simulation library based on the latest features of the C++ language has started as new joint research project of University of Nice Sophia Antipolis, UMR CNRS 7172 (FR), INRIA Sophia Antipolis (FR), and Carleton University (CAN). Of course, anyone interested in joined this effort is more than welcome!
