摘要： An operator graph analysis mechanism analyzes an operator graph corresponding to an application for problems as the application runs, and determines potential reallocations from a reallocation policy. The reallocation policy may specify potential reallocations depending on whether one or more operators in the operator graph are compute bound, memory bound, communication bound, or storage bound. The operator graph analysis mechanism includes a resource reallocation mechanism that can dynamically change allocation of resources in the system at runtime to address problems detected in the operator graph. The operator graph analysis mechanism thus allows an application represented by an operator graph to dynamically evolve over time to optimize its performance at runtime.

摘要翻译： 运算符图分析机制分析应用程序运行时与应用程序相对应的运算符图，并确定重新分配策略的潜在重新分配。 重新分配策略可以根据运算符图中的一个或多个运算符是计算边界，存储器边界，通信限制还是存储绑定来指定潜在的重新分配。 运营商图分析机制包括资源重分配机制，可以在运行时动态地改变系统中资源的分配，以解决运营商图中检测到的问题。 因此，运算符图分析机制允许由运算符图表示的应用随时间动态演变以优化运行时的性能。
