  The electronic commerce is considered as one of the strategies to maintain competitive advantage in the companies. To have a successful electronic commerce in each business, some requirements and infrastructures are needed in advance. "Technical infrastructure" is as the most fundamental and most important infrastructure for electronic commerce. In this study, a comprehensive model is presented that introduces the effective factors on the success of electronic commerce in the technical infrastructure and shows that how by using importance-performance analysis model, it can be possible to identify the undesirable infrastructure factors that lead to unsuccessfulness of electronic commerce in each business and prioritize them for improvement and, technical infrastructure of electronic commerce and it’s capabilities which are necessary for successful implementation will be reviewed and technical infrastructure factor that cause failure of the e-commerce in the tile and ceramic industry of Maybod county, as one of the main centers of ceramic and tile production in the world and the biggest exporter of tiles in Iran, will be evaluated using the " analysis of importance- Performance" method. The results indicate that the internal infrastructure as well as the hardware and software available in theses firms, have acceptable condition and non-use of electronic payments, poor public infrastructure (Internet), lack of enough human force and undesirable capability of websites, are the main factors for failure of electronic commerce in term of technical infrastructure in these firms, respectively.

  Although Sparse matrix-vector multiplication (SPMVs) algorithms are simple, they include important parts of Linear Algebra algorithms in Mathematics and Physics areas. As these algorithms can be run in parallel, Graphics Processing Units (GPUs) has been considered as one of the best candidates to run these algorithms. In the recent years, power consumption has been considered as one of the metrics that should be taken into consideration in addition to performance.  In spite of this importance, to the best of our knowledge, studies on power consumptions in SPMVs algorithms on GPUs are scarce.  In this paper, we investigate the effects of hardware parameters on power consumptions in SPMV algorithms on GPUs. For this, we leverage the possibility of setting the GPU’s parameters to investigate the effects of these parameters on power consumptions. These configurations have been applied to different formats of Sparse Matrices, and the best parameters are selected for having the best performance per power metric. Therefore, as the results of this study the settings can be applied in running different Linear Algebra algorithms on GPUs to obtain the best performance per power. Manuscript profile

  Nowadays, increasing the processing power of supercomputers is a worldwide race. This race, signifies the importance of supercomputers in the current era. They are engines of improving technology in almost all scientific areas, such as computational biology, earth sciences, cosmology, fluid dynamics, and plasma modeling, to name a few. Next generation of supercomputers can be divided into two broad categories: 1) emerging technologies such as neuromorphic and quantum computing and 2) Exascala computing. Emerging technologies will be the future of supercomputing, however, not in a very recent future. Therefore, in this paper, we have focused on Exascale computing, and have tried to provide a comprehensive overview of the main requirements for this technology to be achieved and become available. Requirements have been overviewed from different aspects; hardware, software, artificial intelligence, and cloud computing. In addition, we have attempted to provide a complete taxonomy of hot research topics within this area. Manuscript profile

  Due to the rapid growth of science and technology, their need for high performance computing is increasing everyday. So far, the majority of the world's high performance computing needs have been based on conventional silicon-based technologies, but the end of the age of silicon-based technologies is near, and this fact has led scientists to use emerging technologies such as quantum computing, bio computing, optical computing and similar technologies. Although some of these technologies are not new and the initial introduction of some of them dates back to some decades ago, but due to the attractiveness of classical silicon-based computing and the speed of development in it, have been neglected to date. However, recently, these technologies have begun to be used to build scalable high performance computers. In this paper, we introduce these technologies and how they participate in the field of high performance computing, their current and future status, and their challenges. Also, the taxonomy related to each of these technologies from the computational point of view as well as their research topics are presented, which can be utilized for future research in this field.
