operating system - What happens when Binary Semaphore is Signalled twice? ie. s=1;wait(s); signal(s)signal(s); Does s becomes 0 or it remains 1? -

what happens when binary semaphore signalled twice? i.e. suppose s binary semaphore variable s=1 now following-- wait(s),signal(s),signal(s) does s becomes 0 or remains 1? the binary semaphore used protect resource, 1 process may access @ time. this process wait, which, assuming semaphore 1 (resource isn't busy) make semaphore =0. when process finished resource signal, allowing other processes access resource, making semaphore =1. there's no reason why process signal twice, nor there reason why other process signal before doing wait (let me know if you've thought of one), 2 successive signals error. if writing os primitive implementation i'd judge better idea leave signal @ 1 put 0 , lock resource out time. the standard texts on semaphores talk incrementing , decrementing count, that's because it's useful way of thinking counting semaphores. way actual semaphores behave in actual os when they're used in odd way depends on implemen

How to access a PHP resource -

version control - Easy way to switch/swap git checkins between 2 branches -

Image
i made implementation feature on develop-branch. worked out came interesting alternative. branched checkin of develop-branch before feature checkin on develop implement alternative. decided alternative better implementation. wouldn't want loose first implementation. branches this: i continue on "develop"-branch , keep 1st implementation on "newoverview" branch. there easier way somehow preserve changes of each branch. undo both branch commits. reapply changes correct branch , checkin again? sounds lot of error prone tasks. can tell git take 1st commit , put on "newoverview" branch , 2nd commit put on "develop" branch? ann: repository has master branch. 1 changes merged when finished , develop branch. other branches not pushed server. locally. checkout develop branch git checkout develop create new branch on top of develop save results. don't checkout! git branch alternative reduce develop common ancestor ne

Does caching in spark streaming increase performance -

Image
so i'm preforming multiple operations on same rdd in kafka stream. caching rdd going improve performance? when running multiple operations on same dstream, cache substantially improve performance. can observed on spark ui: without use of cache , each iteration on dstream take same time, total time process data in each batch interval linear number of iterations on data: when cache used, first time transformation pipeline on rdd executed, rdd cached , every subsequent iteration on rdd take fraction of time execute. (in screenshot, execution time of same job further reduced 3s 0.4s reducing number of partitions) instead of using dstream.cache recommend use dstream.foreachrdd or dstream.transform gain direct access underlying rdd , apply persist operation. use matching persist , unpersist around iterative code clean memory possible: dstream.foreachrdd{rdd => rdd.cache() col.foreach{id => rdd.filter(elem => elem.id == id).map(...).saveas...}
