Abstract: A processor modifies memory management mode for a range of memory locations of a multilevel memory hierarchy based on changes in an application phase of an application executing at a processor. The processor monitors the application phase (e.g.,. computation-bound phase, input/output phase, or memory access phase) of the executing application and in response to a change in phase consults a management policy to identify a memory management mode. The processor automatically reconfigures a memory controller and other modules so that a range of memory locations of the multilevel memory hierarchy are managed according to the identified memory management mode. By changing the memory management mode for the range of memory locations according to the application phase, the processor improves processing efficiency and flexibility.

Abstract: A processor discards spill data from a memory hierarchy in response to the final access to the spill data has been performed by a compiled program executing at the processor. In some embodiments, the final access determined based on a special-purpose load instruction configured for this purpose. In some embodiments the determination is made based on the location of a stack pointer indicating that a method of the executing program has returned, so that data of the returned method that remains in the stack frame is no longer to be accessed. Because the spill data is discarded after the final access, it is not transferred through the memory hierarchy.

Abstract translation: 响应于对处理器执行的编译程序已经执行对溢出数据的最终访问，处理器从存储器层次结构中丢弃溢出数据。 在一些实施例中，基于为此目的配置的专用加载指令确定最终访问。 在一些实施例中，基于指示执行程序的方法已经返回的堆栈指针的位置进行确定，使得保留在堆栈帧中的返回的方法的数据不再被访问。 由于溢出数据在最终访问后被丢弃，因此不会通过内存层次结构传输。

Abstract: A cluster compute server stores different types of data at different storage volumes in order to reduce data duplication at the storage volumes. The storage volumes are categorized into two classes: common storage volumes and dedicated storage volumes, wherein the common storage volumes store data to be accessed and used by multiple compute nodes (or multiple virtual servers) of the cluster compute server. The dedicated storage volumes, in contrast, store data to be accessed only by a corresponding compute node (or virtual server).
