Porting multithreading libraries to an exokernel system

Abstract

In this paper, we present an extension to allow multithreaded applications to run on an Intel-based exokernel system. For this purpose, we have ported a user-level threads package to such environment. Our goal is to evaluate the suitability of running multithreaded parallel applications on top of a multiprocessor system managed by an exokernel. We present the design of a prototype library, the lessons learned during its implementation and our proposals for this kind of systems.
