Before chatbots there were simply bots: The invention of a chatbot brought us to the new era of technology, the era of conversation service. A chatbot is a virtual person that can effectively talk to any human being with the help of interactive conversion textual skill. Now a days there are many cloud-based platforms available for developing and deploying the chatbot such as Microsoft bot framework, IBM Watson, Kore, AWS lambda, Microsoft Azure bot service, Chatfuel, Heroku and many more but all those techniques has some drawbacks such as built-in Artificial Intelligence, NLP, conversion service, programming etc. This paper represents the comparison between all cloud-based chatbot technologies with some constraint such as built-in AI, setup time, completion time, complexity etc. Finally, by the comparison, we will get to know that which cloud platform is efficient and suitable for developing chatbot.
SUMMARYOpenMP is emerging as a viable high-level programming model for shared memory parallel systems. It was conceived to enable easy, portable application development on this range of systems, and it has also been implemented on cache-coherent Non-Uniform Memory Access (ccNUMA) architectures. Unfortunately, it is hard to obtain high performance on the latter architecture, particularly when large numbers of threads are involved. In this paper, we discuss the difficulties faced when writing OpenMP programs for ccNUMA systems, and explain how the vendors have attempted to overcome them. We focus on one such system, the SGI Origin 2000, and perform a variety of experiments designed to illustrate the impact of the vendor's efforts. We compare codes written in a standard, loop-level parallel style under OpenMP with alternative versions written in a Single Program Multiple Data (SPMD) fashion, also realized via OpenMP, and show that the latter consistently provides superior performance. A carefully chosen set of language extensions can help us translate programs from the former style to the latter (or to compile directly, but in a similar manner). Syntax for these extensions can be borrowed from HPF, and some aspects of HPF compiler technology can help the translation process. It is our expectation that an extended language, if well compiled, would improve the attractiveness of OpenMP as a language for high-performance computation on an important class of modern architectures.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
