parallel-processing

问题 Is there anyway to stop my loop from being interrupted by the rate limit? I would like my code to wait to execute until the time limit has passed if possible. A side question: I thought about parallelizing the for loop. Do you think this would be a good idea? I was not sure if there would be a chance for data to be written to the wrong file. library(rtweet) create_token(app="Arconic Influential Followers",consumer_key,consumer_secret) flw <- get_followers("arconic") fds <- get_friends(

问题 Can PHP call a function and don't wait for it to return? So something like this: function callback($pause, $arg) { sleep($pause); echo $arg, "\n"; } header('Content-Type: text/plain'); fast_call_user_func_array('callback', array(3, 'three')); fast_call_user_func_array('callback', array(2, 'two')); fast_call_user_func_array('callback', array(1, 'one')); would output one (after 1 second) two (after 2 seconds) three (after 3 seconds) rather than three (after 3 seconds) two (after 3 + 2 = 5

Are they just figured out using the same mechanism as a linear search or is the range narrowed down somehow, similar to a binary search. 回答1: The implementation of a function such as the natural logarithm in any

问题 I have three methods that I call to do some number crunching that are as follows results.LeftFront.CalcAi(); results.RightFront.CalcAi(); results.RearSuspension.CalcAi(geom, vehDef.Geometry.LTa.TaStiffness, vehDef.Geometry.RTa.TaStiffness); Each of the functions is independent of each other and can be computed in parallel with no dead locks. What is the easiest way to compute these in parallel without the containing method finishing until all three are done? 回答1: See the TPL documentation.

问题 I know that now that most processors have two or more cores, multicore programming is all the rage. Is there functionality to utilize this in Java? I know that Java has a Thread class, but I also know this was around a long time before multicores became popular. If I can make use of multiple cores in Java, what class/technique would I use? 回答1: Does Java have support for multicore processors/parallel processing? Yes. It also has been a platform for other programming languages where the

问题 Hi all I wrote a short program that displays an avi file. I need the program to get input from the keyboard while the movie is running (and not after it ends): this is my code: figure('MenuBar','none') set(gcf,'Color', 'white') set(gca,'Color','white'); set(gca,'XColor','white'); set(gca,'YColor','white'); m=aviread('c:/t1.avi') a=30:1:100; b=100:-1:30; c=[a b a b a b a b a b] %to run the movie back and forth movie(m,c) %runs the movie Thank you for any help Ariel 回答1: Maybe you can insert
