An anytime algorithm uses many well defined quality measures to monitor progress in problem solving and distributed computing resources. [2] It keeps searching for the best possible answer with the amount of time that it is given. [5] It may not run until completion and may improve the answer if it is allowed to run longer. [6]
In a system supporting parallel message passing but not pipelining, the message sends x <- a() and y <- b() in the above example could proceed in parallel, but the send of t1 <- c(t2) would have to wait until both t1 and t2 had been received, even when x, y, t1, and t2 are on the same remote machine. The relative latency advantage of pipelining ...
This creates a situation where x will never be greater than 5, since at the start of the loop code, x is assigned the value of 1 (regardless of any previous value) before it is changed to x + 1. Thus the loop will always result in x = 2 and will never break. This could be fixed by moving the x = 1 instruction outside the loop so that its ...
Spinning can also be used to generate an arbitrary time delay, a technique that was necessary on systems that lacked a method of waiting a specific length of time. Processor speeds vary greatly from computer to computer, especially as some processors are designed to dynamically adjust speed based on current workload. [ 1 ]
In logic, linear temporal logic or linear-time temporal logic [1] [2] (LTL) is a modal temporal logic with modalities referring to time. In LTL, one can encode formulae about the future of paths , e.g., a condition will eventually be true, a condition will be true until another fact becomes true, etc.
first checks whether x is less than 5, which it is, so then the {loop body} is entered, where the printf function is run and x is incremented by 1. After completing all the statements in the loop body, the condition, (x < 5), is checked again, and the loop is executed again, this process repeating until the variable x has the value 5.
This behavior limits performance for non-pipelined stop-and-wait request-response application protocol such as HTTP with persistent connection. [ 9 ] Minshall's modification to Nagle's algorithm makes it such that the algorithm always sends if the last packet is full-sized , only waiting for an acknowledgement when the last packet is partial.
F# added asynchronous workflows with await points in version 2.0 in 2007. [5] This influenced the async/await mechanism added to C#. [6] Microsoft first released a version of C# with async/await in the Async CTP (2011). It was later officially released in C# 5 (2012). [7] [1]: 10 Haskell lead developer Simon Marlow created the async package in ...
