Hyper-threading technology speeds clusters

Abstract

The paper describes a new approach to the use of the Hyper-Threading Technology for improving cluster performance. The Hyper-Threading Technology is enabled in 90% of all sold server's CPUs today and in the most cases it improves the overall application performance. The obvious question would be: Does Hyper-Threading Technology improves cluster performance and if so, how it works? In order to get the fully optimized Hyper-Threading Technology enabled cluster it is necessary to focus on 3 elements which can take advantage of Hyper-Threading Technology and moreover they all need to be tuned for this aim. These elements are: operating system, compiler and application.
