Parallel algorithms and efficient implementation techniques for finite element approximations

Radu Popescu

In this thesis we study the efficient implementation of the finite element method for the numerical solution of partial differential equations (PDE) on modern parallel computer archi- tectures, such as Cray and IBM supercomputers. The domain-decomposition ...

Porting an MPEG-HEVC decoder to a low-power many-core platform

Marco Mattavelli, Simone Casale Brunet, Claudio Paolo Alberti, Damien Jack De Saint Jorre

After several generations of video coding standards, MPEG High Efficient Video Coding (HEVC) is likely to emerge as the video coding standards for HD and Ultra-HD TV. HEVC decoding is expected to be less computationally demanding and to provide a higher le ...

Multi-Lane FlowPools: A Detailed Look

Martin Odersky, Philipp Haller, Aleksandar Prokopec, Tobias Schlatter

FlowPools, proposed by are a powerful way to express dataflow logic in highly parallelized applications. The original paper proposes two ways of implementing a FlowPool: Single-Lane FlowPools (SLFP) and Multi-Lane FlowPools (MLFP). While SLFPs showed decen ...

On the Performance of Software Transactional Memory

Aleksandar Dragojevic

The recent proliferation of multi-core processors has moved concurrent programming into mainstream by forcing increasingly more programmers to write parallel code. Using traditional concurrency techniques, such as locking, is notoriously difficult and has ...

Embarrassingly Scalable Database Systems

Anastasia Ailamaki

From Wikipedia-An embarrassingly parallel workload (or embarrassingly parallel problem) is one for which little or no effort is required to separate the problem into a number of parallel tasks. This is often the case where there exists no dependency (or co ...

OpenMP parallelization of the three-dimensional distinct lattice spring model

Jiannong Fang, Liang Sun, Gaofeng Zhao, Jianbo Zhu

This paper presents the OpenMP parallel implementation of the Distinct Lattice Spring Model (DLSM). The motivation of this study is to reduce the computing time and increase the computational capacity of the DLSM code. Firstly, the basic theory of DLSM is ...

Efficient System-Enforced Deterministic Parallelism

Bryan Alexander Ford

Deterministic execution offers many benefits for debugging, fault tolerance, and security. Current methods of executing parallel programs deterministically, however, often incur high costs, allow misbehaved software to defeat repeatability, and transform t ...

Performance prediction and race detection in message-passing parallel applications

Basile Schäli

The combination of low cost clusters and multicore processors lowers the barrier for accessing massive amounts of computing power. As computational sciences advance, the use of in silico simulations to complement in vivo experiments promises parallel progr ...

Scheduling threads for constructive cache sharing on CMPs

Anastasia Ailamaki, Babak Falsafi

In chip multiprocessors (CMPs), limiting the number of offchip cache misses is crucial for good performance. Many multithreaded programs provide opportunities for constructive cache sharing, in which concurrently scheduled threads share a largely overlappi ...
