Comparing Operating Systems Scalability on Multicore Processors by Microbenchmarking

Abstract: SUMMARYMulticore processor architectures have become ubiquitous in today's computing platforms, especially in parallel computing installations, with their power and cost advantages. While the technology trend continues towards having hundreds of cores on a chip in the foreseeable future, an urgent question posed to system designers as well as application users is whether applications can receive sufficient support on today's operating systems for them to scale to many cores. To this end, people need to underst… Show more

“…One of the most challenging tasks for a data warehouse application is to execute a query as fast as possible against a large amount of data. As the multi‐core processors have seen a very fast evolution in the last decade and the scalability of distributed systems has also improved significantly , one can assume that the most efficient way to lower the query processing time is to parallelize their execution. Numerous studies have been performed regarding the parallel execution of queries in a database or data warehouse .…”
