摘要： A system and method for altering the operation of a computer application while avoiding recompiling the computer application or modifying the kernel associated with the operating system of a computing device. A computer application is launched in a suspended mode. An asynchronous procedure call (APC) is used to load an additional dynamic link library (DLL) to be associated with the computer application. The additional DLL includes routines that operate differently than routines originally associated with the computer application through an initial DLL. The references to the routines within the computer application are redirected to the routines of the additional (DLL). The operation of the computer application is therefore changed while avoiding rewriting the application or changing the operating system.

摘要： Described is a mechanism for dynamically allocating receive buffers on a server to a plurality of clients in a network environment. The server maintains a list of the number of transaction credits in use by each client, the number of transaction credits allocated to each client, and the number of pending transaction requests that are not being handled due to a limitation on the number of allocated transaction credits. The transaction credits correspond to the receive buffers. In a resource constrained situation, the server computes an equitable distribution of the available credits and reallocates the available credits based on that equitable distribution.

摘要： A method and system for offloading I/O processing from a first computer to a second computer, using RDMA-capable network interconnects, are disclosed. The method and system include a client on the first computer communicating over an RDMA connection to a server on the second computer by way of a lightweight input/output (LWIO) protocol. The protocol generally comprises a network discovery phase followed by an I/O processing phase. During the discovery phase, the client and server determine a minimal list of shared RDMA-capable providers. During the I/O processing phase, the client posts I/O requests for offloading to the second machine over a mutually-authenticated RDMA channel. The I/O model is asymmetric, with read operations being implemented using RDMA and write operations being implemented using normal sends. Read and write requests may be completed in polling mode and in interrupt mode. Buffers are managed by way of a credit mechanism.

摘要： To reconstitute a ghosted file for use, a single ghosting filter on a computing device locates ghosting information in the metadata of the ghosted file and locates within the ghosting information an identification of a particular ghosting manager of the computing device, where the identified ghosting manager is responsible for the ghosted file. Thereafter, the ghosting filter communicates to the identified ghosting manager a request to obtain data of the ghosted file from a corresponding alternate location, and the identified ghosting manager does in fact obtain such requested data from such alternate location. Upon receiving the requested data of the ghosted file from the identified ghosting manager, then, the ghosting filter reconstitutes the received data to the ghosted file. The single ghosting filter is generic to all of the ghosting managers of the computing device.

摘要： An improved remote protocol enables efficient and reliable updating of files on a remote server. A gather-copy extension to a remote protocol enables a client to instruct a server to gather portions of data from an existing source file on the server and to copy those portions of data to appropriate offsets within a new destination file on the server. The gather-copy extension thus enables the client to leave blank locations in the destination file into which the client can write new data during a file update. The gather-copy extension also enables the client to effectively delete portions of the source file by not copying them from the source file to the destination file. File updates can therefore be made without having to transfer the entire file from the client to the server.
摘要翻译：改进的远程协议可以高效可靠地更新远程服务器上的文件。远程协议的收集副本扩展使客户端能够指示服务器从服务器上的现有源文件收集数据部分，并将这些部分数据复制到服务器上的新目标文件中的适当偏移量。收集副本扩展因此使得客户端能够在目的地文件中留下空白位置，客户端可以在文件更新期间写入新数据。收集副本扩展还使客户端能够通过不将源文件从源文件复制到目标文件来有效地删除源文件的部分。因此，可以进行文件更新，而无需将整个文件从客户端传输到服务器。

摘要： An effective I/O protocol for taking advantage of system area network functionality, whether or not a particular application is written to do so, is provided. Transparently to the application, the I/O protocol routes application I/O commands via legacy transmission protocols or via remote direct memory access protocols as appropriate. When communicating via remote direct memory access protocols, the I/O protocol can take advantage of multiple data exchange commands implemented by these protocols to perform the required data exchange. Once an I/O operation has completed, the I/O protocol passes a completion notification to the application using a polling or interrupt construct.

摘要： A computer system has a CPU, a stack cache and a main memory. The main memory is a conventional untagged memory, where each memory location is a word having a bit size that is an integer power of 2 (e.g., 32, 64 or 128 bits per word). However, at least one stack cache associated with the CPU (and preferably integrated with the CPU on the same semiconductor circuit or in the same chip set) is a tagged memory where each data word of the stack cache has an associated tag. Whenever the stack cache overflows with data, at least a portion of the contents of the stack cache are stored in a previously established location in main memory so as to make room for storing additional data in the stack cache. In this stack cache swap out operation, the data values and tags in N evaluation stack entries of the evaluation stack cache are copied to the previously established main memory location. The N tags in the N copied evaluation stack entries are stored into a first predefined portion of the previously established main memory location, and the N data values in the N copied evaluation stack entries are stored into a second predefined portion of the previously established main memory location. During a cache fill operation, the N tags and data values of a stack block are copied from their respective main memory positions into the tag and data portions of a stack cache block.
摘要翻译：计算机系统具有CPU，堆栈高速缓存和主存储器。主存储器是常规的未标记存储器，其中每个存储器位置是具有位大小为2的整数幂（例如，每个字32,64或128位）的字。然而，与CPU相关联的至少一个堆栈缓存（并且优选地与同一半导体电路上的CPU集成在同一芯片组中）是标记的存储器，其中堆栈高速缓存的每个数据字具有相关联的标签。每当堆栈缓存溢出数据时，堆栈高速缓存的内容的至少一部分被存储在主存储器中的先前建立的位置中，以便在堆栈高速缓存中存储额外的数据。在该堆栈缓存交换操作中，评估堆栈高速缓存的N个评估堆栈条目中的数据值和标签被复制到先前建立的主存储器位置。 N个复制的评估堆栈条目中的N个标签被存储到先前建立的主存储器位置的第一预定义部分中，并且N个复制的评估堆栈条目中的N个数据值被存储到先前建立的主存储器的第二预定义部分位置。在缓存填充操作期间，堆栈块的N个标签和数据值从它们各自的主存储器位置复制到堆栈高速缓存块的标签和数据部分。

摘要： The present invention provides a novel client side caching (CSC) infrastructure that supports transition states at the directory level to facilitate a seamless operation across connectivity states between client and remote server. More specifically, persistent caching is performed to safeguard the user (e.g., client) and/or the client applications across connectivity interruptions and/or bandwidth changes. This is accomplished in part by caching to a client data store the desirable file(s) together with the appropriate file access parameters. Moreover, the client maintains access to cached files during periods of disconnect. Furthermore, portions of a path can be offline while other portions upstream can remain online. CSC operates on the logical path which cooperates with DFS which operates on the physical path to keep track of files cached, accessed and changes in the directories. In addition, truth on the client is facilitated whether or not a conflict of file copies exists.
摘要翻译：本发明提供了一种新颖的客户端缓存（CSC）基础设施，其支持目录级别的转换状态，以促进跨客户端和远程服务器之间的连接状态的无缝操作。更具体地，执行持续高速缓存以跨连接中断和/或带宽改变来保护用户（例如，客户端）和/或客户端应用。这部分是通过将客户端数据存储器连同适当的文件访问参数一起缓存所需的文件来实现的。此外，客户端在断开连接期间保持对缓存文件的访问。此外，路径的一部分可以离线，而上游的其他部分可以保持联机。 CSC在与物理路径上运行的DFS协作的逻辑路径上运行，以跟踪缓存，访问和更改目录中的文件。此外，无论文件副本是否存在冲突，客户端上的真相都是有利的。
