Where is my application…

Spending Time? Wasting Time? Waiting Too Long?

• Focus tuning on functions taking time

• See call stacks• See time on source

• See how efficient you run your parallel code

• Show threads which are running or runable

• See locks by wait time

• Red/Green for CPU utilization during wait

Focus your application optimization efforts where it counts – Intel® VTune™ Amplifier XE for MeeGo* helps to analyze applications without

source and binary instrumentation

“TBB helped KnowledgeMinerachieve speeds 8x faster on an 8 core system. In addition, a strict redesign of KnowledgeMiner for parallel computing is giving a total speedup over the previous version 400x. This astonishing change in speed allows KnowledgeMiner to operate in almost real time, something we didn’t previously think was possible.”

Frank LemkeFounder and President

KnowledgeMiner Software

Intel® Threading Building Blocks

• Scalable performance

• Make multi-threaded application development practical

– A C++ template library that uses familiar task patterns, not threads

– A high level abstraction requiring less code for threading without sacrificing performance

• Maximize application performance

– Appropriately scales to the number of cores available

• Works with Intel® Hyper-Threading technology enabled Intel® Atom™ processors, as well as dual-core processors

• Available as open source at opentbb.org

Optimization Notice

Optimization Notice

Intel compilers, associated libraries and associated development tools may include or utilize options that optimize for instruction sets that are available in both Intel and non-Intel microprocessors (for example SIMD instruction sets), but do not optimize equally for non-Intel microprocessors. In addition, certain compiler options for Intel compilers, including some that are not specific to Intel micro-architecture, are reserved for Intel microprocessors. For a detailed description of Intel compiler options, including the instruction sets and specific microprocessors they implicate, please refer to the “Intel Compiler User and Reference Guides” under “Compiler Options." Many library routines that are part of Intel compiler products are more highly optimized for Intel microprocessors than for other microprocessors. While the compilers and libraries in Intel compiler products offer optimizations for both Intel and Intel-compatible microprocessors, depending on the options you select, your code and other factors, you likely will get extra performance on Intel microprocessors.

Intel compilers, associated libraries and associated development tools may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include Intel® Streaming SIMD Extensions 2 (Intel® SSE2), Intel® Streaming SIMD Extensions 3 (Intel® SSE3), and Supplemental Streaming SIMD Extensions 3 (Intel SSSE3) instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors.

While Intel believes our compilers and libraries are excellent choices to assist in obtaining the best performance on Intel and non-Intel microprocessors, Intel recommends that you evaluate other compilers and libraries to determine which best meet your requirements. We hope to win your business by striving to offer the best performance of any compiler or library; please let us know if you find we do not.
