What models of computation are for modeling distributed systems? Posted: 21 Feb 2021 07:22 PM PST PRAM is a model of computation for shared memory systems. I was wondering what models of computation are for modeling distributed (memory) systems? In particular, what models are often used for analyzing performance of distributed algorithms? submitted by /u/timlee126 [link] [comments]

Dr. John Hennessy || Spotlight Lecture Series || Shaastra, IIT Madras Posted: 22 Feb 2021 01:52 AM PST https://preview.redd.it/pl3j485240j61.png?width=4500&format=png&auto=webp&s=aed2a843f42b8d24d3b037079c4eddc3303ef7e7 Shaastra Spotlight is back bigger and better than ever with a series of exciting fireside chats, fascinating lectures and intriguing demonstrations to inspire and take you through an enthralling journey of transformative learning. We are proud to announce the first fireside chat of the Spotlight Lecture series with Dr. John L. Hennessy, Chairman of Alphabet Inc., the parent company of Google. Dr. Hennessy also served as the tenth president of Stanford University and was among the first leaders to establish Silicon Valley and hence is fondly referred to as the "Godfather of Silicon Valley". Dr. Hennessy won the 2017 Turing Award for developing the RISC architecture, which is now used in most of the new computer chips. Catch his enthralling chat live only on Atthah & Shaastra IITM's YouTube channel on 28th February (Sunday) at 1:00 PM IST.

Is an abstract machine necessarily stateful? Posted: 22 Feb 2021 03:36 AM PST In theory of computation, what is an abstract machine? https://en.wikipedia.org/wiki/Abstract_machine says An abstract machine, also called an abstract computer, is a theoretical computer used for defining a model of computation. A In the theory of computation, abstract machines are often used in thought experiments regarding computability or to analyze the complexity of algorithms (see computational complexity theory). A typical abstract machine consists of a definition in terms of input, output, and the set of allowable operations used to turn the former into the latter. The best-known example is the Turing machine. Are an abstract machine and a model of computation the same concept? What is the difference between an abstract machine and an automaton? Is an abstract machine necessarily a stateful model of computation? Is the lambda calculus (which is a stateless model of computation) an abstract machine? Thanks. submitted by /u/timlee126 [link] [comments]

What is a Segment Tree? Posted: 22 Feb 2021 02:08 AM PST submitted by /u/aayusss21 [link] [comments]

Is an online PC scanner considered a SaaS? Posted: 21 Feb 2021 05:37 AM PST I'm a bit confused as to what the characteristics to a SaaS is. Like what makes a software saas? Also is an online pc optimizer more efficient than a software downloaded on the PC, or it makes no difference? submitted by /u/Annimios [link] [comments]
