摘要： A computing system and method employing a processor device for generating real addresses associated with memory locations of a real memory system for reading and writing of data thereto, the system comprising: a plurality of memory blocks in the real memory system for storing data, a physical memory storage for storing the pages of data comprising one or more real memory blocks, each real memory block partitioned into one or more sectors, each comprising contiguous bytes of physical memory; a translation table structure in the physical memory storage having entries for associating a real address with sectors of the physical memory, each translation table entry including one or more pointers for pointing to a corresponding sector in its associated real memory block, the table accessed for storing data in one or more allocated sectors for memory read and write operations initiated by the processor; and, a control device for directly manipulating entries in the translation table structure for performing page operations without actually accessing physical memory data contents. In this system, the actual data of the pages involved in the operation are never accessed by the processor and therefore is never required in the memory cache hierarchy, thus eliminating the cache damage normally associated with these block operations. Further the manipulation of the translation table will involve reading and writing a few bytes to perform the operation as opposed to reading and writing the hundreds or thousands of bytes in the pages being manipulated.
摘要翻译：一种计算系统和方法，所述计算系统和方法采用处理器设备来生成与实际存储器系统的存储器位置相关联的用于读取和写入数据的实际地址，所述系统包括：所述实际存储器系统中的用于存储数据的多个存储块，用于存储包括一个或多个实际存储器块的数据页面的存储器存储器，每个实际存储器块被划分成一个或多个扇区，每个扇区包括物理存储器的连续字节; 物理存储器存储器中的转换表结构具有用于将实际地址与物理存储器的扇区相关联的条目，每个转换表条目包括用于指向其相关联的实际存储器块中的对应扇区的一个或多个指针，用于由处理器发起的用于存储器读和写操作的一个或多个分配扇区中的数据; 以及用于直接操纵翻译表结构中的条目以执行页面操作而不实际访问物理存储器数据内容的控制装置。在该系统中，操作所涉及的页面的实际数据从不被处理器访问，因此在存储器高速缓存层次结构中从不需要这样的数据，从而消除通常与这些块操作相关联的高速缓存损坏。此外，翻译表的操作将涉及读取和写入几个字节以执行操作，而不是在被操纵的页面中读取和写入数百或数千字节。

摘要： A system and method for allocating resources in a cloud environment includes determining permitted usage of virtual machines and partitioning resources between network servers in accordance with a virtual hypervisor generated in accordance with an abstraction layer configured as an interface between a solution manager and an interface to a cloud network. Resource usage limits are determined for each virtual machine associated with the virtual hypervisor, and the servers are analyzed through the virtual hypervisors to determine if the virtual machines need to be migrated. If reallocation is needed, virtual machine migration requests are issued to migrate virtual machines into a new configuration at the virtual hypervisor abstraction level. The servers are reanalyzed to determine if migration of the new configuration is needed. Shares are computed to enforce balance requirements, and virtual machine shares and limits are adjusted for resources according to the computed shares.
