摘要： In some embodiments, the invention involves a framework for using virtualization technology to efficiently support a domain-specific run-time environment. In at least one embodiment, a framework is utilized to take advantage of virtualization technology (VT) to partition performance critical and non-performance critical tasks of the same domain-specific application. An embodiment of the invention utilizes a general-purpose operating system to execute non-performance critical aspects of a domain, and uses a privileged VT-root mode to execute performance critical aspects of the domain. Another embodiment uses one or more guest VMs to execute the performance critical aspects of the domain-specific run-time environment. Other embodiments are described and claimed.

摘要： In some embodiments, the invention involves a novel combination of techniques for prefetching data and passing messages between and among cores in a multi-processor/multi-core platform. In an embodiment, a receiving core has a message queue and a message prefetcher. Incoming messages are simultaneously written to the message queue and the message prefetcher. The prefetcher speculatively fetches data referenced in the received message so that the data is available when the message is executed in the execution pipeline, or shortly thereafter. Other embodiments are described and claimed.

摘要： A compiler transforms source code into intermediate code and provides the intermediate code to a profiler. The profiler executes the intermediate code. The profiler generates a performance profile that indicates the performance of the intermediate code, and annotates the intermediate code based, at least in part, on data from the performance profile. The compiler receives annotated intermediate code from the profiler and transforms the annotated intermediate code into machine code. Alternatively, the compiler transforms intermediate code to machine code and provides the machine code to a profiler. The profiler executes the machine code and generates a data file that indicates the performance of the machine code. The compiler receives the data file, and modifies the machine code based on the data file.

摘要： A filtering face-piece respirator 10 that has a support structure 16 and a filtering structure 18. The filtering structure 18 includes first and second transversely extending members 26, 28 that can move toward and apart from each other in the longitudinal direction. The filtering structure 18 has a filtration layer 52 and a pleat 58. The pleat 58 allows the filtering structure 18 to contract and expand when the first and second transversely-extending members 26, 28 move toward and apart from each other, respectively. This ability to expand and contract in an accordion-like manner enables the mask body to better accommodate wearer jaw movement.
