摘要： Strong semantics are provided to programs that are correctly synchronized in their use of transactions by using dynamic separation of objects that are accessed in transactions from those accessed outside transactions. At run-time, operations are performed to identify transitions between these protected and unprotected modes of access. Dynamic separation permits a range of hardware-based and software-based implementations which allow non-conflicting transactions to execute and commit in parallel. A run-time checking tool, analogous to a data-race detector, may be provided to test dynamic separation of transacted data and non-transacted data. Dynamic separation may be used in an asynchronous I/O library.

摘要： A general purpose high-performance distributed execution engine can be used by developers to deploy large-scale distributed applications. To allow developers to easily make use of the distributed execution engine, a graph building language is proposed that enables developers to efficiently create graphs (e.g., direct acyclic graphs) that describe the subprograms to be executed and the flow of data between them. A job manager (or other appropriate entity) reads the description of the graph created with the graph building language, builds the graph based on that description, and intelligently distributes the subprograms according to the graph so that system resources are used efficiently. In one embodiment, the graph building language (and, thus, the description of the graph) includes syntax for replication, pointwise connect, cross connect and merge.

摘要： A general purpose high-performance distributed execution engine for coarse-grained data-parallel applications is proposed that allows developers to easily create large-scale distributed applications without requiring them to master concurrency techniques beyond being able to draw a graph of the data-dependencies of their algorithms. Based on the graph, a job manager intelligently distributes the work load so that system resources are used efficiently. The system is designed to scale from a small cluster of a few computers, or the multiple CPU cores on a powerful single computer, up to a data center containing thousands of servers.

摘要： In a computer implemented method, a client computer connected to a public network such as the Internet makes a request for an intranet resource to a tunnel of a firewall isolating the intranet from the Internet. The request is made in a public message. The tunnel sends a message to the client computer to redirect to a proxy server of the tunnel. The client computer send a token and the request for the resource the proxy server. If the token is valid, the request is forwarded to the intranet, otherwise, the user of the client computer must first be authenticated.

摘要： A mesh connected local area network provides automatic packet switching and routing between host computers coupled to the network. The network has a multiplicity of cut-through, nonblocking switches, each capable of simultaneously routing a multiplicity of data packets. Low host-to-host latency is achieved through the use of cut-through switches with separate internal buffers for each packet being routed. The switches are interconnected with one another and are coupled to the host computers of the network by point to point full duplex links. While each switch can be coupled to ten or more network members, i.e., switches and hosts, each link is coupled to only two network members and is dedicated to carrying signals therebetween. Whenever a new switch or link is added to the network, and whenever a switch or link fails, the switches in the network automatically reconfigure the network by recomputing the set of legal paths through the network.

摘要： Methods and systems are provided for a cancellation server maintaining a database of identifiers of cryptographic puzzles. A cryptographic puzzle is created from a unique identifier and a timestamp, and is attached to an electronic mail message, along with the puzzle's solution. The recipient verifies that the solution is correct and that the timestamp is current, and further queries the cancellation server with the puzzle identifier. If the identifier does not exist in the database, then the recipient knows the received message is legitimate. If the identifier already appears in the database, the received message can be automatically removed from the recipient's computer.

摘要： In a computerized distributed mail system, a plurality of client computers are connected to each other via a network. Each client computer is configured to execute client mail application programs. A mail service system is also connected to the network. The system is for executing server mail programs on server computers. The mail service system includes an index server for storing mail messages in message files, and for storing a full-text index of the mail messages. In addition, the system includes means for accessing the mail messages by the plurality of client computers by searching the full-text index using queries.
