Microprocessor-based systems today are composed of multi-core, multi-threaded
processors with complex cache hierarchies and gigabytes of main memory. Accurate …

In this paper, we present different combined clustering methods and we evaluate their
performances and their results on a dataset with ground truth. This dataset, built from several …

Data synchronization-long a staple in le systems-is emerging as a signicant communications
primitive. In a distributed system, data synchronization resolves di erences among …

Detailed microarchitectural models are necessary to predict, explain, or optimize the
performance of software running on modern microprocessors. Building such models often …

Servet is a suite of benchmarks focused on detecting a set of parameters with high influence
on the overall performance of multicore systems. These parameters can be used for …

With exascale computing forthcoming, performance metrics such as memory traffic and
arithmetic intensity are increasingly important for codes that heavily utilize numerical …

The latest trends in high performance computing systems show an increasing demand on
the use of a large scale multicore system in an efficient way so that high compute‐intensive …

SUMMARY The popularity of Partitioned Global Address Space (PGAS) languages has
increased during the last years thanks to their high programmability and performance …

DARPA's AACE project aimed to develop Architecture Aware Compiler Environments. Such
a compiler automatically characterizes the targeted hardware and optimizes the application …

The goal of this thesis is to improve the understanding of the achieved application
performance on existing hardware. It can be observed that the scaling of parallel …
