Abstract: A method for analyzing data reordering operations in Single Issue Multiple Data source code and generating executable code therefrom is provided. Input is received. One or more data reordering operations in the input are identified and each data reordering operation in the input is abstracted into a corresponding virtual shuffle operation so that each virtual shuffle operation forms part of an expression tree. One or more virtual shuffle trees are collapsed by combining virtual shuffle operations within at least one of the one or more virtual shuffle trees to form one or more combined virtual shuffle operations, wherein each virtual shuffle tree is a subtree of the expression tree that only contains virtual shuffle operations. Then code is generated for the one or more combined virtual shuffle operations.

Abstract: In an embodiment, if a self thread has more than one conflict, a transaction of the self thread is aborted and restarted. If the self thread has only one conflict and an enemy thread of the self thread has more than one conflict, the transaction of the self thread is committed. If the self thread only conflicts with the enemy thread and the enemy thread only conflicts with the self thread and the self thread has a key that has a higher priority than a key of the enemy thread, the transaction of the self thread is committed. If the self thread only conflicts with the enemy thread, the enemy thread only conflicts with the self thread, and the self thread has a key that has a lower priority than the key of the enemy thread, the transaction of the self thread is aborted.

Abstract: Avoiding data conflicts includes initiating a transactional lock elision transaction containing a critical section, executing the transactional lock elision transaction including the critical section, and checking a status of a lock prior to a commit point in the transactional lock elision transaction executing, wherein the checking the status occurs after processing the critical section. A determination of whether the status of the lock checked is free is made and, responsive to a determination the lock checked is free, a result of the transactional lock elision transaction is committed.

Abstract: A mechanism is provided for path-sensitive analysis for reducing rollback overheads. The mechanism receives, in a compiler, program code to be compiled to form compiled code. The mechanism divides the code into basic blocks. The mechanism then determines a restore register set for each of the one or more basic blocks to form one or more restore register sets. The mechanism then stores the one or more register sets such that responsive to a rollback during execution of the compiled code. A rollback routine identifies a restore register set from the one or more restore register sets and restores registers identified in the identified restore register set.

Abstract: Disclosed are compositions and methods for reducing dentin hypersensitivity. Also disclosed are compositions containing calcium fluoride nanoparticles.

Abstract: In an embodiment, asynchronous conflict events are received during a previous rollback period. Each of the asynchronous conflict events represent conflicts encountered by speculative execution of a first plurality of work units and may be received out-of-order. During a current rollback period, a first work unit is determined whose speculative execution raised one of the asynchronous conflict events, and the first work unit is older than all other of the first plurality of work units. A second plurality of work units are determined, whose ages are equal to or older than the first work unit, wherein each of the second plurality of work units are assigned to respective executing threads. Rollbacks of the second plurality of work units are performed. After the rollbacks of the second plurality of work units are performed, speculative executions of the second plurality of work units are initiated in age order, from oldest to youngest.

Abstract: A process for check pointing in speculative execution frameworks, identifies calls to a set of setjmp/longjmp instructions to form identified calls to setjmp/longjmp, determines a control flow path between a call to a setjmp and a longjmp pair of instructions in the identified calls to setjmp/longjmp and replaces calls to the setjmp/longjmp pair of instructions with calls to an improved_setjmp and improved_longjmp instruction pair. The process creates a context data structure in memory, computes a non-volatile save/restore set and replaces the call to improved_setjmp of the setjmp/longjmp pair of instructions with instructions to save all required non-volatile and special purpose registers and replaces a call to improved_longjmp of the setjmp/longjmp pair of instructions with instructions to restore all required non-volatile and special purpose registers and to branch to an instruction immediately following a block of code containing the call to improved_setjmp.

Abstract: Generating mixed-mode operations in the compilation of program code for processors having vector or SIMD processing units is disclosed. In a preferred embodiment of the present invention, program instructions making up the body of a loop are abstracted into virtual vector instructions. These virtual vector instructions are treated, for initial code optimization purposes, as vector instructions (i.e., instructions written for the vector unit). The virtual vector instructions are eventually expanded into native code for the target processor, at which time a determination is made for each virtual vector instruction as to whether to expand the virtual vector instruction into native vector instructions, into native scalar instructions, into calls to pre-defined library functions, or into a combination of these. A cost model is used to determine the optimal choice of expansion based on hardware/software constraints, performance costs/benefits, and other criteria.

Abstract: Embodiments of the present invention relate to a method for a near non-adaptive virtual metrology for wafer processing control. In accordance with an embodiment of the present invention, a method for processing control comprises diagnosing a chamber of a processing tool that processes a wafer to identify a key chamber parameter, and controlling the chamber based on the key chamber parameter if the key chamber parameter can be controlled, or compensating a prediction model by changing to a secondary prediction model if the key chamber parameter cannot be sufficiently controlled.

Abstract: A method is disclosed for rendering messages in an email application on a client computer. A plurality of email messages is received from a server computer, including a first email message, a second email message and a third email message. The first email message is rendered on the client computer with a first conversation icon that identifies the first email message as being part of an email conversation thread. When the first conversation icon is selected on the first email message, a view is rendered showing one or more email messages in the conversation thread. When the second email message is selected, the second email message is rendered on the client computer with a second conversation icon. When the second conversation icon is selected on the second email message, the view showing the one or more email messages in the conversation thread is rendered.

Abstract: Disclosure for using SLP in processing a plurality of statements, wherein the statements are associated with an array having a number of array positions, and each statement includes one or more expressions. Expressions are gathered for each of the statements into a structure comprising a single merge stream furnished with a location for each expression. The location for a given expression is associated with one of the array positions. A plurality of expressions are selectively identified and SLP packing operations are applied to the identified expressions to merge into one or more isomorphic sub-streams. Expressions of the isomorphic sub-streams and other expressions of the single merge stream are combined into a number of input vectors that are substantially equal in length to one another. A location vector is generated that contains the respective locations for all of the expressions in the single merge stream.

Abstract: Generating loop code to execute on Single-Instruction Multiple-Datapath (SIMD) architectures, where the loop operates on datatypes having different lengths, is disclosed. Further, a preferred embodiment of the present invention includes a novel technique to efficiently realign or shift arbitrary streams to an arbitrary offset, regardless whether the alignments or offsets are known at the compile time or not. This technique enables the application of advanced alignment optimizations to runtime alignment. Length conversion operations, for packing and unpacking data values, are included in the alignment handling framework. These operations are formally defined in terms of standard SIMD instructions that are readily available on various SIMD platforms. This allows sequential loop code operating on datatypes of disparate length to be transformed (“simdized”) into optimized SIMD code through a fully automated process.
