Abstract: Improved end-to-end server-client communication is achieved, wherein a thin client requests services from a server using a condensed optimized protocol. A mediator is provided on the server, which translates encoded messages from the client into standard web service request formats. Results are re-encoded at the server and returned to the client. A code generator is provided to automatically create optimized and specialized client and server code using templates, in which the code is optimized according to the characteristics of the client and the specified services. Grouped messages are supported. Bandwidth consumption is reduced by the technique, which increases the performance of resource-constrained clients, such as small wireless devices.

Abstract: Apparatus, methods, and computer program products are disclosed that enable a first computer and a second computer to mutually authenticate each other over a network. A first computer sends first authentication evidence to a second computer. The first authentication evidence is used to prove to the second computer that the first computer has access to a first plurality of authentication secrets without exposing the first plurality of authentication secrets. In addition, the second computer sends second authentication evidence to the first computer. The second authentication evidence is used to prove to the first computer that the second computer has access to a second plurality of authentication secrets without exposing the second plurality of authentication secrets. The first plurality of authentication secrets is related to the second plurality of authentication secrets. Thus, the first computer is authenticated to the second computer and the second computer is authenticated to the first computer.

Abstract: Multi-threaded, transactional memory systems may allow concurrent execution of critical sections as speculative transactions. These transactions may abort due to contention among threads. Hardware feedback mechanisms may detect information about aborts and provide that information to software, hardware, or hybrid software/hardware contention management mechanisms. For example, they may detect occurrences of transactional aborts or conditions that may result in transactional aborts, and may update local readable registers or other storage entities (e.g., performance counters) with relevant contention information. This information may include identifying data (e.g., information outlining abort relationships between the processor and other specific physical or logical processors) and/or tallied data (e.g., values of event counters reflecting the number of aborted attempts by the current thread or the resources consumed by those attempts).

Abstract: One embodiment of the present invention provides a system that performs a lock-free update to one or more fields in an existing node in a linked list. To perform the update, the system first obtains a new node to be added to the linked list, wherein other processes do not possess references to the new node and therefore cannot initially access the new node. Next, the system copies a snapshot of the existing node to the new node, and then updates one or more fields in the new node that correspond to the one or more fields in the existing node. Next, in a single atomic operation the system modifies a next pointer of the existing node to point to the new node and also marks the next pointer to indicate that the existing node is deleted. In this way, the new node becomes part of the linked list and the existing node is deleted in a single atomic operation.

The source type information may indicate that the source is remote or local; that it is a shared or a private storage location; that the data is supplied via a cache-to-cache transfer; or that the data is sourced from a coherency domain other than that of the requesting process. Instructions, events, messages, and replies may be sampled, and extended address information corresponding to the samples may be stored in an event set database for performance analysis.

Abstract: An apparatus and method for scheduling execution of multiple threads on a shared processor resource is described in connection with a multithreaded multiprocessor chip. Using a thread selection policy that switches between available threads every cycle to give priority to the least recently executed or scheduled threads, different threads are able to operate in a way that ensures no deadlocks or livelocks while maximizing aggregate performance and fairness between threads. Prioritization is accomplished by monitoring and sorting thread status information for each thread, including speculative states in which a thread may be speculatively scheduled, thereby improving usage of the execution pipeline by switching a thread in with a lower priority.

Abstract: A dual edge triggered flip flop can pass data values on a clock rising or falling edge. The dual edge triggered flip flop can be operated at half the clock speed of a single edge triggered flip flop and produce substantially the same throughput. The dual edge triggered flip flop may use less power than a single edge triggered flip flop due at least in part to the construction of an intermediate gate as a data interlock gate. The dual edge triggered flip flop may contain a plurality of master nodes, and is soft error hardened compared to a single edge triggered flip flop.

Abstract: An optical module is described. This optical module includes at least two optical devices that communicate with each other using edge-to-edge optical coupling of an optical signal between optical components in the two optical devices. Note that the edge-to-edge optical coupling may occur without mode converters at edges of either of the optical devices. Furthermore, the edge-to-edge optical coupling may be facilitated by an alignment substrate, which is mechanically coupled to the two optical devices. This alignment substrate aligns the edges of the two optical devices so that they are approximately parallel to each other, and aligns the optical components in the two optical devices.

Abstract: A system and method for speculatively parallelizing non-countable loops in a multi-threaded application. A multi-core processor receives instructions for a multi-threaded application. The application may contain non-countable loops. Non-countable loops have an iteration count value that cannot be determined prior to the execution of the non-countable loop, a loop index value that cannot be non-speculatively determined prior to the execution of an iteration of the non-countable loop, and control that is not transferred out of the loop body by a code line in the loop body. The compiler replaces the non-countable loop with a parallelized loop pattern that uses outlined function calls defined in a parallelization library (PL) in order to speculatively execute iterations of the parallelized loop. The parallelized loop pattern is configured to squash and re-execute any speculative thread of the parallelized loop pattern that is signaled to have a transaction failure.
