支持主线程中的子线程并行执行程序和调用算子。 一旦启动子线程由线程 ID 标识该线程 ID 是一个取决于操作系统的整数进程号。 子线程的执行独立于它们启动的线程。 因此无法预测子线程执行结束确切时间点。 如果要访问一组线程返回的数据则需要显式等待相应的线程完成。
HDevelop 默认将线程数限制为 20。 如果需要可以在首选项中修改此数字。 完全限制并发线程数的主要原因是为了防止用户由于编程错误而无意中生成大量线程。 在这种情况下系统负载和内存消耗可能会增长得如此之高以至于可能会变得无响应。 启动线程 par_startUserThreadID : 算子/方法
par_start 不是实际的算子而只是修改调用行为的限定符。 因此无法在操作员窗口中选择 par_start。如果启动新的子线程会超过配置的最大线程数则会引发异常。
