    摘要： Core dump is performed over a network without relying on network device drivers. Instead of network device drivers, firmware of network devices that is typically used during boot is preserved in memory post-boot, and one or more application program interfaces of the firmware are invoked to perform the network core dump. For ease of implementation, a network bootstrap program that has standard application program interfaces for calling into the firmware of network devices may be invoked when performing core dump over the network.

    摘要： An engine (TOE) is provided in a virtualized computer system for offloading I/O tasks using any defined protocol such as TCP/IP. The system includes a virtual machine (VM), which has a guest operating system (OS) that runs via a virtual machine monitor (VMM) on a system-level software platform (vmkernel), which also forms the software interface layer to at least one physical network connection device. A TCP/IP stack is included in vmkernel. During normal I/O operation, for sockets associated with TOE, processes in an application layer in the guest OS are able to communicate directly with vmkernel's TCP/IP stack, thereby bypassing the guest OS kernel.

    摘要： Method and system for performing a namespace operation in a distributed file system. The file system is disposed on a plurality of partition servers, and each partition server controls access to a subset of hierarchically-related, shared storage objects. Each namespace operation involves a namespace object and a target object that are part of the shared storage objects. Namespace operations received at each partition server are serialized. In response to an unlink namespace operation, a reference in the namespace object to the target object is removed, and after removal the target object is modified in accordance with the unlink operation. In response to a link operation, the target object is modified consistent with the link operation. After modification of the target object, a reference to the target object is inserted in the namespace object.

    摘要： In a method of improving querying, a plurality of items of information are transformed into a plurality of vectors, where each item of information of the plurality of items of information is mapped to a respective vector of said plurality of vectors. A plurality of vectors is associated with a subset of nodes selected from a plurality of nodes. Each vector associated with a respective node of said plurality of nodes is based on a similarity between each vector of said plurality of vectors.
