Singular Manual: startTasks

| #### D.2.13.6 startTasks Procedure from library `tasks.lib` (see tasks_lib). Usage: startTasks(t1, t2, ...), t1, t2, ... tasks Return: nothing. Starts the tasks t1, t2, ... and sets their states to 'started'. Note: A task whose state is neither 'created' nor 'stopped' cannot be started. If startTasks() is applied to a task whose state is 'stopped', then the computation of this task will be restarted from the beginning. Tasks can be started from within other tasks. A started task should not be accessed from within any task other than the one within which it was started. For each task, the start of its computation is subject to the internal scheduling. Example:
    LIB "tasks.lib";
    ring R = 0, (x,y), dp;
    ideal I = x9y2+x10, x2y7-y8;
    task t1 = "std", list(I);
    task t2 = "slimgb", list(I);
    startTasks(t1, t2);
    waitAllTasks(t1, t2);
    getResult(t1);
    ==> _[1]=x2y7-y8
    ==> _[2]=x9y2+x10
    ==> _[3]=x12y+xy11
    ==> _[4]=x13-xy12
    ==> _[5]=y14+xy12
    ==> _[6]=xy13+y12
    getResult(t2);
    ==> _[1]=x2y7-y8
    ==> _[2]=x9y2+x10
    ==> _[3]=x12y+xy11
    ==> _[4]=x13-xy12
    ==> _[5]=xy13+y12
    ==> _[6]=y14+xy12
    killTask(t1);
    killTask(t2);
