c - How to share a linked list to all process with MPI -

-

im kinda new mpi , im having troubles this.

lets have list

struct list{     int number;     int process;     list *next; }

i created linked list in main process, dont know how send linked list process every process can operation in portion of list.

if manually send list around, have traverse , send each , every element of queue, creating massive communication overhead.

the best way convert list contiguous array of structs , distribute processes via mpi_scatter (or mpi_scatterv if size of list not divisible number of ranks). if must, can locally convert linked list on each rank.

without knowing rest of program i'd there strong chance using linked list bad choice anyway , should use array data in first place.

i have order , ordersearch models. in order list (actionindex) gridview there filtering , sorting. on of columns in order order_total (sum of products in order). i need implement sum of order_total in gridview. if manually counting activedataprovider->getmodels() array_map spend 3 seconds 3000 orders (localhost). don't want miss time. i see 2 ways make faster: create cache every filter , update lifetime (horrible) the interesting can right in ordersearch->search() method $query method. don't understand how can pass in controller. example of code 2nd way: class ordersearch extends order { public $totalsum; public function search($params) { $query = order::find(); $dataprovider = new activedataprovider([ 'query' => $query, ]); $this->load($params); $this->totalsum = $query->sum('order_total'); // works fast return $dataprovider; } } after i

Sass watch command compiles .scss files before full sftp upload -

i use winscp download , edit .scss files , sass on linux (on server) compile them .css . after saving file, use: sass scss/style.scss css/style.css , replaces css file compiled sccs. the problem i want skip part return command line after editing scss file, sake of automation , saving time. but, if use watch command: sass --watch scss/style.scss:css/style.css synchronize 2 files, alerts nonexistent css errors pop up: change detected to: scss/style.scss error scss/style.scss (line 232: invalid css after "...ht: bold; line-": expected "{", "") note that when file uploads quicker usual (sometimes happens) watch command job, no errors. this because, when file upload takes time, sass compiles scss file (on server) before uploaded remote folder. thus, compiles part of file, resulting in css errors. is there way set timer watch command waits few seconds after detects changes , before compiling? any other way overcome is, of course,
