摘要： Goal state indicators can be communicated from a fabric controller of a computer cluster to each of multiple compute instances in the computer cluster managed by the fabric controller. The goal state indicators can be formatted according to a structured protocol that defines multiple possible goal states. Additionally, status reports can be received from the compute instances. Each of the status reports can indicate a current state of one of the compute instances relative to a goal state previously indicated in a goal state indicator communicated to that one of the compute instances.

摘要： Methods and systems for adjusting an operating system configuration according to changes in hardware components of a client computer. The adjusted operating system can boot on the client computer regardless of changes in the hardware configuration of the client computer since it was last connected to a network server. Before the operating system boots, a preliminary connection is established between the client computer and the server. During the preliminary connection, the system identifies hardware components that are new and that must be supported by the operating system for bootup to occur. In particular, the server sends information relating to the previous client hardware configuration to the client computer. The client computer compares its current hardware configuration to the previous hardware configuration information, thereby identifying its new hardware components. Information identifying the new hardware components is sent to the server. The server locates operating system components or device drivers that support the new hardware components and stores them in a specified repository at the server. The operating system, which is now reconfigured to support the current client hardware components, is downloaded to the client computer and boots thereon.

摘要： A method and system for scheduling the execution of a plurality of threads in a computer system to control the concurrency level. Operating system data structures, called "queue objects," control the number of threads that are concurrently active processing incoming requests to an application program, a server or other processor of requests. The queue objects keep track of how many threads are currently active, and ensure that the number of active threads is at or near a predetermined target level of concurrency. By ensuring that new threads are not added to the pool of active threads if the system is operating at or above the target level of concurrency, the queue objects minimize the number of superfluous context switches that the operating system must perform and thus increases system efficiency and throughput.

摘要： Increased efficiency in booting a computer uses a process of logging physical-level disk access during a boot cycle for use in creating a boot plan for a subsequent boot. Processing the log from one or more previous boots removes unnecessary reads such as those associated with temporary files and then orders the remaining read accesses based on times of prior read accesses and and by physical location on the disk. Upon boot, data likely to be requested first orders the remaining read accesses based on times of prior read accesses and By taking advantage of disk head and platter characteristics, data is read in sweeps through the disk, reducing overall latency. Requests that are not in cache may be held if the data is already scheduled for retrieval.

摘要： Methods and systems for recognizing a client computer as a replacement for a previous client computer or as being new to a computer network. When a client computer is connected to a server in a computer network, the client computer sends its unique identifier to the server. The server compares the unique identifier against a list of known unique identifiers. If the server determines that the unique identifier is unknown, the client computer prompts the user to select one of a list of user options, which include, for example, a replacement computer option and a new computer option. If the user selects the replacement computer option, the user also identifies the previous computer that has been replaced. The server then replaces the previous computer's unique identifier with the replacement computer's unique identifier, and assigns the replacement computer to an appropriate server computer. If the user instead selects the new computer option, the server assigns the new computer to an appropriate server computer. The methods may further include identifying the hardware components of the new or replacement computer and modifying operating system components with little or no user assistance.

摘要： A remote boot process uses a secret to sign and/or seal the data necessary to remotely boot a client from a server on a network to ensure the integrity of the data. The secret is generated by the server and securely delivered to the client during the initial setup of the client. The secret contains a one-way encryption of the password for the client account on the server. Each side balances a signed message with a verify and a sealed message with an unseal. Subsequent transactions between the client and server are conducted using messages encrypted with a key generated by the server and securely delivered to the client in a message sealed using the secret. The secret can also be used in conjunction with an access data structure to prevent unauthorized users from accessing data stored on the server on behalf of the client or other users. In other aspects of the invention, the secret is replaced by a client private/public key pair.
