The precise estimation of dynamic power consumption, power droop and temperature development during scan test require a very large number of time-aware gate-level logic simulations. Until now, such characterizations have been feasible only for rather small designs or with reduced precision due to the high computational demands. We propose a new, throughput-optimized timing simulator on […]

Flipping is a local and efficient operation to construct the convex hull in an incremental fashion. However, it is known that the traditional flip algorithm is not able to compute the convex hull when applied to a polyhedron in R3. Our novel Flip-Flop algorithm is a variant of the flip algorithm. It overcomes the deficiency […]

The level-set method is one of the most popular techniques for capturing and tracking deformable interfaces. Although level sets have demonstrated great potential in visualization and computer graphics applications, such as surface editing and physically based modeling, their use for interactive simulations has been limited due to the high computational demands involved. In this paper, […]

Modern parallel computing devices such as the graphics processing unit (GPU) have gained significant traction in scientific computing, and are particularly well-suited to data-parallel algorithms such as the particle filter. Of the components of the particle filter, the resampling step is the most difficult to implement well on such devices, as it often requires a […]

The HPEC charter is to be the premier conference in the world on the confluence of HPC and Embedded Computing. The High Performance Extreme Computing (HPEC) technical committee announces the Seventeenth Annual HPEC conference to be held 24–26 September 2013 at the Westin Hotel in Waltham, Massachusetts. The technical committee seeks new presentations that clearly […]

General-purpose graphics processing units (GPGPU) have emerged as an important class of shared memory parallel processing architectures, with widespread deployment in every computer class from high-end supercomputers to embedded mobile platforms. Relative to more traditional multicore systems of today, GPGPUs have distinctly higher degrees of hardware multithreading (hundreds of hardware thread contexts vs. tens), a […]

GPUs employ thousands of threads per core to achieve high throughput. These threads exhibit localities in control-flow, instruction and data addresses and values. In this study we investigate inter-warp instruction temporal locality and show that during short intervals a significant share of fetched instructions are fetched unnecessarily. This observation provides several opportunities to enhance GPUs. […]

In this paper, we discuss a novel approach of improving the performance and accuracy of parallelization compilers by utilizing massively parallel processing power of GPGPU (General Purpose Graphical Processing Units). With the advent of multi core processors, it has become necessary to use parallel programming methodologies. However, parallel programmers need tools that can provide support […]

Smooth Particle Hydrodynamics is a Lagrangian meshless numerical method with substantially improved capabilities in simulation of both fluid dynamics and solid mechanics due to its meshless nature. GPUSPH is an implementation of Smoothed Particle Hydrodynamics (SPH) on Nvidia CUDA-enabled (graphics) cards. In this paper the GPUSPH is applied to runup and overtopping applications and compared […]

CONTEXT: Bouncing collisions of dust aggregates within the protoplanetary may have a significant impact on the growth process of planetesimals. Yet, the conditions that result in bouncing are not very well understood. Existing simulations studying the bouncing behavior used aggregates with an artificial, very regular internal structure. Aims: Here, we study the bouncing behavior of […]

The advent of mainframe computing brought about a fundamentally different way of approaching problems for many branches of science. But none has transformed quite like the science of biology. With genome sequencing now commonplace, an organism may be completely represented as a sequence of numbers. Harnessing the power of computers, sequences of genomes (and thus […]
