Optimization Notice

Thinking about 2 points,• Expanding software businesses• Technologies creating new opportunities

Page 3: Advancing HPC == advancing the business of software

Software and Services Group3

Optimization Notice

To Expand the Use of HPC Methods,• Technology advances – solve an interesting

problem at a lower price point– Big HPC drives creativity, which must trickle

down to profitability in volume• New users need approachable, simplified

software– Volume & price point – consider video editing

• Software is a business too– Hardware sales are not enabling software

development– “why do developers rob banks”?

Software and Services Group4

Optimization Notice

Support Software Business• Thought Leaders should provide a path for

new software applications to grow• Consider a pathfinding activity– Purchasing a new offering– Aiding a university research code

• Speak in favor of licensing models which work to expand use

Optimization Notice

Increase Parallel Programming Creativity with New Methods

• All of life is not MPI• Cilk Plus, TBB

Page 6: Advancing HPC == advancing the business of software

Software and Services Group6

Optimization Notice

Intel® Cilk™ Plus• For C++• Parallelization of unequal work units• Easy to get started: cilk_spawn, cilk_sync,

cilk_for• Adds array notations from Fortran• Achieves vectorization• Just announced availability in a gcc branch

Software and Services Group7

Optimization Notice

Intel® Threading Building Blocks (Intel® TBB)

• A C++ template library• With many models of parallelism, not just

a loop– Unequal work units– Load balancing– Work stealing task scheduling– Recently introduced a graph model

• Available in open source format

Software and Services Group8

Optimization Notice

Seek out the new parallel methods• Production quality, getting good results• To add parallelism where it hasn’t gone

before• We need expansion of parallelism to drive

forward

Optimization Notice

Optimization NoticeIntel® 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.
