fork-join

问题 I am looking for an implementation of the fork-join model for Python. As Java's ForkJoinPool, it should allow to split (fork) the work of a task into several sub tasks recursively. Once the sub tasks are completed, the results are joined and returned. Ideally, it should support threads and processes similar to the ThreadPoolExecutor and ProcessPoolExecutor in concurrent.futures, but threads are more important for now. It must allow to limit the number of threads (I want to have one thread per

问题 In my Angular2-typescript app, I'm using forkJoin to return an Observable only once all the parallel HTTP calls were made. Issue : the subscription callback keeps being executed indefinitely Here is my code: http.service import {Http} from "@angular/http"; constructor (private _http: HTTP) {} makeGetRequest(....) { return this._http.get(URL) .map (res => res.json) .toPromise(); my.service import {Observable} from "rxjs/Observable"; import {HttpService} from "http.service" constructor (private

问题 I use the ForkJoinPool to execute tasks in parallel. When I look at the logout put of my program it seems that the ForkJoinPool creates a huge amount of workers to execute my tasks (there are log entries that look like this: 05 Apr 2016 11:39:18,678 [ForkJoinPool-2-worker-2493] <message> ). Is there a worker for each tasks created which is then executed according to the number of parallelism I configured in the ForkJoinPool or am I doing something wrong? Here is how I do it: public class
