System and method for dynamic optimizations using security assertions
The invention relates to a system and method for efficient security runtime. If the same security demand for permissions occurs twice during the same code path (i.e. execution stack) the latter can be automatically turned (optimized) into a security assertion based on the former demand. A security runtime can determine which assertions to establish in a call stack, using declarative security information kept in an assembly metadata and based on execution history to know what has already been demanded for a specific stack frame. If the method being called has been allowed to execute before then a demand may be replaced with an assertion for the same permissions within the call stack. If that frame was executed then it means the security demand was successfully evaluated. Furthermore, if the permission evaluation result is known to be static (e.g., its result will not change) it can be determined that another check on the same permissions is not required higher on the stack, so this demand can safely be replaced by an assertion, which can effectively speed up the code execution without sacrificing security.

Network AV system
While a client reproduces a moving picture, and fast-forward reproducing is carried out in the process of reproducing a moving picture based on a frame, the client transmits a search request to a server. The server searches for the frame of I picture based on a condition in the search request in the fast-forwarding direction (reproducing direction) from the frame. The server uses a search table it has. As a result of the search, the server sequentially extracts frames of I picture and transmits them to the client. The client reproduces the frames every time it receives one of them. Therefore, a network AV system allows the memory capacity of a client to be reduced as much as possible and capable of special reproducing such as fast-forward reproducing and reverse-reproducing.

Pipelined LDPC arithmetic unit
An improvement to an arithmetic unit of a low-density parity-check decoder, where the arithmetic unit has a pipelined architecture of modules. A first module calculates a difference between absolute values of md_R and md_g_in, and passes the result to a first Gallager module. The first Gallager module converts this value from a p0/p1 representation to a 2*p0−1 representation, and passes the result to a second module. The second module selectively adjusts the result of the previous module based on the sign values of md_g_in and md_R, and passes one of its outputs to a third module (the other two outputs, loc_item_out and hard_out, are not a part of the pipeline). The third module calculates a new md_g value by adding the result of the second module and loc_item_in, and passes this result to a fourth module. The fourth module separates a sign and an absolute value of the new md_g, and passes the result to a second Gallager module. The second Gallager module converts the result from the 2*p0−1 representation to the p0/p1 representation and the final value leaves the unit as md_g_out.

System and method for increasing error checking performance by calculating CRC calculations after multiple test patterns for processor design verification and validation
A system and method to reduce verification time by sharing memory between multiple test patterns and performing results checking after each test pattern executes one time is presented. A test pattern generator generates multiple test pattern sets, each of which including multiple test patterns.

Since the invention described herein waits until all test patterns have executed before performing a memory error detection check, less time is spent on memory error detection checks, which allows more time to execute test patterns.

Avoiding livelock using a cache manager in multiple core processors
Livelocks are prevented in multiple core processors by verifying that a data access request is still valid before sending messages to processor cores that may cause other data access requests to fail.

Dynamic extension of network-accessible services
Services deployed in a network computing environment (such as a Web services implementation model) are transparently extended. Preferably, handler components in an engine that processes requests and responses provide the extensions. A handler for outgoing messages adds the extensions to a response message that is created responsive to receiving a request message that asks for a service's available operations. A client receiving this response message can then invoke one of the extensions, without knowing that it is an extension. A handler for incoming messages checks received requests: if a request for an extension is received, the handler routes that message to a location other than the service itself; otherwise, incoming requests for operations that are actually available from the service are routed thereto. Extensions may provide additional operations such as, but not limited to, management operations, dynamic enabling/disabling of service operations, and/or controlled access to service operations—even though the service itself might contain no operations for these.

When the address is a telephone number, the user acquires the communication terminal address of the communication server, and transmits a voice communication request to the communication server. Thereafter, the voice communication processing is performed through the communication server.

Asynchronous broadcast for ordered delivery between compute nodes in a parallel computing system where packet header space is limited
Disclosed is a mechanism on receiving processors in a parallel computing system for providing order to data packets received from a broadcast call and to distinguish data packets received at nodes from several incoming asynchronous broadcast messages where header space is limited. In the present invention, processors at lower leafs of a tree do not need to obtain a broadcast message by directly accessing the data in a root processor's buffer. Instead, each subsequent intermediate node's rank id information is squeezed into the software header of packet headers. In turn, the entire broadcast message is not transferred from the root processor to each processor in a communicator but instead is replicated on several intermediate nodes which then replicated the message to nodes in lower leafs. Hence, the intermediate compute nodes become “virtual root compute nodes” for the purpose of replicating the broadcast message to lower levels of a tree.

The PCMM message includes at least some information, for example QoS information, embedded in the session initiation request. The method further includes selecting, via the policy server, a set of network resources for creating a path connecting the network endpoints.

The invention incorporates the use of nearest neighbor and overlapping heartbeat connections between clustered computers that are logically organized in a linear or multi-dimensional array.

This membership architecture is well suited to distributed applications (such as a partitioned database) in which changes to the workload are made and propagated cluster-wide by neighboring hosts for purposes of load-balancing.
