In this paper, we address the problem of dynamic resource allocation in presence of job run- time uncertainty. We develop an execution delay model for runtime prediction, and design an adaptive stochastic allocation ...

In the multi-core era, the size of the software operation space, i.e. hardware configurations (number of cores and operating frequency) that provide different software performance and energy consumption, is significantly ...

Service Level Agreements (SLAs) specify the strict terms under which cloud services must be provided. The assessment of the quality of services being provided is critical for both clients and service providers. In this ...

Previous work proposed and evaluated Speculative taskloop (STL) on Intel Core implementing new clauses and constructs in OpenMP. The results indicated that, despite achieving some speed-ups, there was a phenomenon called ...

Single-core architectures have hit the end of the road and industry and academia are currently exploiting new multicore design alternatives. In special, heterogeneous multicore architectures have attracted a lot of attention ...

Software Transactional Memory (STM) systems have poor performance under high contention scenarios. Since many transactions compete for the same data, most of them are aborted, wasting processor runtime. Contention management ...
