摘要： Commands are processed by hardware within a virtual client computing environment, such as graphics-related commands processed by graphics hardware. A server computing device includes graphics hardware, a virtual client computing environment, and a server computing environment. The graphics hardware processes graphics-related commands into responses. The virtual client computing environment includes an encoding application that issues the commands. The server computing environment includes a decoding application. The encoding application includes a first thread that receives the commands and places them onto a first queue. The encoding application includes a second thread that receives the responses from a second queue and communicates the responses to a remote display device. The decoding application includes a third thread that receives the commands from the first queue, communicates the commands to the graphics hardware, receives the responses from the graphics hardware, and places the responses onto the second queue.

摘要： Memory allocation requests are satisfied from a memory pool or from lookaside lists, based on the memory size requested to be allocated. A method, for each of a number of future differently sized memory allocations, determines which memory allocations are to be satisfied from a lookaside list, and which memory allocations are to be satisfied from a memory pool. For each memory allocation to be satisfied from a lookaside list, a corresponding lookaside list for the allocation is initialized. A table is constructed that has a number of entries corresponding to all the differently sized memory allocations. Each entry corresponding to a memory allocation to be satisfied from a lookaside list points to the lookaside list for that memory allocation.

摘要： A method and system for tracking usage of memory in a computer system is provided. Arguments for both the size of a memory allocation and the type of memory being allocated are reserved in a fixed location. A first fixed location is reserved for small memory allocations, i.e. less than one page, and a second fixed location is reserved for large memory allocations, i.e. one page or larger. The fixed location is selected based upon a determination of the size of an allocation required by a calling application. Upon receipt of a memory allocation request by the calling application, a pointer is returned to the calling application identifying the fixed location. Similarly, upon release of memory by the calling application, a counter is decremented to track the amount of memory in use by the application.
摘要翻译：提供了一种用于跟踪计算机系统中的存储器的使用的方法和系统。存储器分配的大小和正在分配的存储器的类型的参数在固定位置保留。第一固定位置被保留用于小存储器分配，即小于一页，并且第二固定位置被保留用于大的存储器分配，即一页或更大的存储器分配。基于确定呼叫应用所需的分配大小来选择固定位置。当由呼叫应用接收到存储器分配请求时，将指针返回给标识固定位置的呼叫应用。类似地，当由呼叫应用释放存储器时，计数器递减以跟踪应用使用的存储器的量。

摘要： A method and system for maintaining integrity of metadata associated with a migrated file. Following migration of data from a source filesystem to a destination filesystem, a tool is automatically invoked to detect if there are any differences in metadata associated with the files and/or folders at each location. Each select field of the metadata at the source filesystem is reviewed to ensure that it matches with the equivalent field at the destination filesystem. In the event at least one of the reviewed metadata fields does not match, an error is generated and forwarded to an operator.

摘要： A method and system are provided for managing a spin state of individual physical disks in a distributed file system. Spin control messages are forwarded to a specified physical disk asynchronously with an I/O command and prior to receipt of the data request by the physical disk. This enables the spin state of the physical disk to be responsive to the I/O command with minimal delay.

摘要： A method and system are provided for directing a client to a preferred service instance. At creation of a service instance, the service binding attribute of the created instance is extended to include assigned domains and associated priorities. There are then two phases to directing a client to the preferred service instance. The first phase is compilation of a list of domains and priorities for the service in response to a query. Upon completion of the first phase, a second phase is executed to determine a preferred service for the client by comparing fully qualified domain name entries and assigned priority entries.

摘要： Sessions states within virtual machine (VM) environments are maintained. Each VM environment hosts a guest operating system (OS) and one or more application programs running. The guest OS and the application computer programs of each VM environment constitute a session. A connection broker maintains a state machine as to states of the sessions and permits transitions among the states in response to messages, commands, and internal decisions. Different types of agents may send the messages, and the commands. The states of the sessions may include a pending state and a number of other states. The pending state is an interim state that indicates a session is being transitioned from one of the other states to another of the other states. These other states may include an offline state, an online-down state, an online-up state, a suspended state, an active state, an idle state, a disconnected state, and a failed state.

摘要： An apparatus, system, and method are disclosed for cache synchronization within a multi-tier system having multiple client-server relationships. The apparatus includes a pre-synchronization module, a locking module, and a synchronization module. The pre-synchronization module receives a pre-synchronization call from an upstream node coupled to a first downstream node. The locking module locks a first cache coupled to the first downstream node in response to a synchronization call from the upstream node. The synchronization module synchronizes source data on the upstream node with cached data on the first cache. The apparatus also may include a post-synchronization module to perform any necessary cleanup activities. Advantageously, the apparatus, system, and method reduce the likelihood of a system deadlock due to premature locking of the first downstream cache, which prevents a subsequent downstream cache from synchronizing with the first cache.
摘要翻译：公开了一种用于具有多个客户机 - 服务器关系的多层系统中的高速缓存同步的装置，系统和方法。该装置包括预同步模块，锁定模块和同步模块。预同步模块从耦合到第一下游节点的上游节点接收预同步呼叫。响应于来自上游节点的同步调用，锁定模块锁定耦合到第一下游节点的第一高速缓存。同步模块将上游节点上的源数据与第一个缓存上的缓存数据进行同步。该装置还可以包括执行任何必要的清除活动的后同步模块。有利地，装置，系统和方法减少了由于第一下游高速缓存的过早锁定而导致的系统死锁的可能性，这阻止随后的下游高速缓存与第一高速缓存同步。
