CBIR is the method of searching the digital images from an image database. "Content-based" means that the search analyzes the contents of the image rather than the metadata such as colours, shapes, textures, or any other information that can be derived from the image itself. The GPU is a powerful graphics engine and a highly […]

In this paper, we consider power-aware task scheduling (PATS) in HPC clouds. Users request virtual machines (VMs) to execute their tasks. Each task is executed on one single VM, and requires a fixed number of cores (i.e., processors), computing power (million instructions per second – MIPS) of each core, a fixed start time and non-preemption […]

Graphical processing units (GPUs) have become widely adopted in the medical imaging community. The parallel SIMD nature of GPUs maps perfectly to many reconstruction algorithms. Because of this, it is relatively straightforward to parallelize common reconstruction algorithms (e.g. FDK backprojection). This means that significant performance improvements must come from careful memory optimizations, exploiting ASICs and […]

As a population-based algorithm, Ant Colony Optimization (ACO) is intrinsically massively parallel, and therefore it is expected to be well-suited for implementation on GPUs (Graphics Processing Units). In this paper, we present a novel ant colony optimization algorithm (called GACO), which based on Compute Unified Device Architecture (CUDA) enabled GPU. In GACO algorithm, we utilize […]

In this paper we present computational cost estimates for parallel shared memory isogeometric multi-frontal solver. The estimates show that the ideal isogeometric shared memory parallel direct solver scales as O(p^2 log(N/p)) for one dimensional problems, O(Np^2) for two dimensional problems, and O(N^(4/3)p^2) for three dimensional problems, where N is the number of degrees of freedom, […]

Parallel programming has become simple and reasonable with the preamble of GPGPUs. Now a day’s many programmers transfer their application to GPGPUs with the accessibility of APIs such as NVIDIA’s CUDA. But it is very tricky task to write CUDA program. Most of the industry extensively uses the immense serial C code, and they are […]

We present a novel approach to perform collision detection queries between rigid and/or deformable models. Our method can handle arbitrary deformations and even discontinuous ones. For this, we subdivide the whole scene with all objects into connected but totally independent parts by a fuzzy clustering algorithm. Following, for every part our algorithm performs a Principal […]

So high integration of IC design and mix VLSI design have brought new complexity in IC design. This complexity brings new challenges for simulation IC time. There is interest to speed up Spice [1] simulation because for large IC simulation can take several days. Average 75% percent of simulation time is spent in evaluating transistor […]

With the rapid growth of next generation sequencing technologies, such as Slex, more and more data have been discovered and published. To analysis such huge data the computational performance is an important issue. Recently, many tools, such as SOAP, have been implemented on Hadoop and GPU parallel computing architectures. BLASTP is an important tool, implemented […]

We propose the Reconstruction Toolkit (RTK, http://www.openrtk.org), an open-source toolkit for fast cone-beam CT reconstruction, based on the Insight Toolkit (ITK) and using GPU code extracted from Plastimatch. RTK is developed by an open consortium (see affiliations) under the non-contaminating Apache 2.0 license. The quality of the platform is daily checked with regression tests in […]

The development of computational systems that mimics the physiological response of organs or even the entire body is a complex task. One of the issues that makes this task extremely complex is the huge computational resources needed to execute the simulations. For this reason, the use of parallel computing is mandatory. In this work, we […]
