Abstract
Operating system kernels typically offer a fixed set of mechanisms and
primitives. However, recent research shows that the attainment of high
performance for a variety of parallel applications may require the
availability of variants of existing primitives or additional low-level
mechanisms best suited for specific applications. One approach to
addressing this need is to offer an adaptable and extensible operating
system kernel.
In this paper, we present a model for adaptive objects and associated
mechanisms which may be used for the development of high performance
operating system kernels for parallel and distributed systems. We use
the model to implement a class of multiprocessor locks namely, adaptive
locks which adapt themselves according to user-provided adaptation
policies to suit any application locking pattern. Using a well-known
multiprocessor application, the Travelling Sales Person program, we
demonstrate the performance advantage of adaptive locks over existing
locks.
