An Automated Tool for Converting Directive Based C Code Into Parallel CUDA Code

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 […]

Collision Detection Based on Fuzzy Scene Subdivision

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 […]

Architectural Support for Virtual Memory in GPUs

The proliferation of heterogeneous compute platforms, of which CPU/GPU is a prevalent example, necessitates a manageable programming model to ensure widespread adoption. A key component of this is a shared unified address space between the heterogeneous units to obtain the programmability benefits of virtual memory. Indeed, processor vendors have already begun embracing heterogeneous systems with […]

Parallel Circuit Simulation on Graphical Processing Unit

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 […]

Local Alignment Tool Based on Hadoop Framework and GPU Architecture

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 […]

The Reconstruction Toolkit (RTK), an open-source cone-beam CT reconstruction toolkit based on the Insight Toolkit (ITK)

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 […]

Use of Multiple GPUs to Speedup the Execution of a Three-Dimensional Computational Model of the Innate Immune System

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 […]

Comparative Study of Frequent Itemset Mining Techniques on Graphics Processor

Frequent itemset mining (FIM) is a core area for many data mining applications as association rules computation, clustering and correlations, which has been comprehensively studied over the last decades. Furthermore, databases are becoming gradually larger, thus requiring a higher computing power to mine them in reasonable time. At the same time, the improvements in high […]

Challenges and Advances in Large-scale DFT Calculations on GPUs, webinar

Recent advances in reformulating electronic structure algorithms for stream processors such as graphical processing units have made DFT calculations on systems comprising up to O(10 to the 3) atoms feasible. Simulations on such systems that previously required half a week on traditional processors can now be completed in only half an hour. Join Professor Heather […]

Energy-Efficient FPGA Implementation for Binomial Option Pricing Using OpenCL

Energy efficiency of financial computations is a performance criterion that can no longer be dismissed, and is as crucial as raw acceleration and accuracy of the solution. In order to reduce the energy consumption of financial accelerators, FPGAs offer a good compromise with low power consumption and high parallelism. However, designing and prototyping an application […]
