Pressure poisson equation is the most time consuming part of the solvers and hence this part is imported on to GPU. Pressure Poisson equation is solved by the conventional Gauss siedel method. Present day modern graphics hardware has several hundred cores which can be effectively used by CFD solvers to parallelize the computation.

Graphics processing units (GPUs), on the other hand, are massively parallel platforms with attractive performance to price and power ratios, used extensively in the recent years for acceleration of data parallel computations. CUDA or Compute Unified Device Architecture is a C-based programming model proposed by NVIDIA for leveraging the parallel computing capabilities of the GPU for general purpose computations. This paper attempts to integrate CUDA acceleration into the Hadoop distributed processing framework to create a heterogeneous high performance image processing system. As Hadoop primarily is used for text analysis, this involves facilitating efficient image processing in Hadoop. Our experimental evaluations using a Adaboost based face detection algorithm indicate that CUDA-enabling a Hadoop cluster, even with low-end GPUs, can result in a 25% improvement in data processing throughput, indicating that an integration of these two technologies can help build scalable, high throughput, power and cost-efficient computing platforms.","PeriodicalId":344858,"journal":{"name":"2013 National Conference on Parallel Computing Technologies (PARCOMPTECH)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126404248","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The simulation framework comprises of mesoscale modelling of evolution of grain growth and microstructure incorporating the system energetics of grain boundary energy and stored energy which are essentially the driving force for the evolution process. An in-house MC computer code has been developed and implemented in the GARUDA grid. This facilitated achieving faster convergence of the MC algorithm for a given lattice structure. The simulated grain growth and microstructure evolution have been successfully validated with the published data.

The problem has been addressed in the proposed work in two modules. The first module describes about the construction of ontology based on relationship between cloud services and their characteristics. In the second module, a generic based search engine has been developed to search the cloud services for user's requirement. It uses cloud ontology to process the query and fetch the results. The cloud services are ranked on the basis of the cloud service characteristics.
