根据Running user code in parallel，我按照以下方式启动模拟：
./simulator platform.xml deployment.xml --cfg=contexts/nthreads:2
但我有一个错误：
Segmentation fault.
Segmentation fault (core dump)
然后我尝试将ptask07模型添加到main中，希望它会有所帮助：
MSG_config("host/model", "ptask_L07");
现在我的模拟在几次执行作业后挂起。
也许我应该添加一些额外的配置来启用代码的并行执行？ （当我运行没有contexts/nthreads的代码时，它可以正常工作。）
UPD ： 我的回溯是。据说，它试图找到模糊点：
