An Adaptive Technique for Constructing Robust and High-Throughput Shared Objects
Abstract. Shared counters are the key to solving a variety of coordination problems on multiprocessor machines, such as barrier synchronization and index distribution. It is desired that they, like shared objects in general, be robust, linearizable and scalable. We present the first linearizable and wait-free shared counter algorithm that achieves high throughput without a-priori knowledge about the system's level of asynchrony. Our algorithm can be easily adapted to any other combinable objects as well, such as stacks and queues. In particular, in an N-process execution E, our algorithm achieves high throughput of ( N 2 E log2 E log N ), where E is E's level of asynchrony. Moreover, our algorithm stands any constant number of faults. If E contains a constant number of faults, then our algorithm still achieves high throughput of ( N 2 E log2 E log N ), where E bounds the relative speeds of any two processes, at a time that both of them participated in E and none of them faile...
