In this paper we explore database segmentation in the context of a column-store DBMS targeted at a scientific database. We present a novel hardware- and scheme-oblivious segmentati...
We obtain analytically, the energy optimal speed profile of a generic multi-speed device with a discrete set of speeds, to execute a given task within a given time. Current implem...
Current shared memory multicore and multiprocessor systems are nondeterministic. Each time these systems execute a multithreaded application, even if supplied with the same input,...

In Software Transactional Memory (STM), contention management refers to the mechanisms used to ensure forward progress-to avoid livelock and starvation, and to promote throughput ...

Network-on-Chips (NoCs) are quite latency sensitive, since their communication latency strongly affects the application performance on recent many-core architectures. To reduce th...
