Advanced Tools to Develop Code for Intel® Xeon® Processors Today, Easily Extends to Intel® MIC

Architecture

“By just utilizing standard programming on both Intel® Xeon processor and Intel® MIC architecture based platforms, the performance met multi-threading scalability expectations and we observed near-theoretical linear performance scaling with the number of threads.” – Hongsuk Yi,

Heterogeneous Computing Team

Leader, KISTI Supercomputing Center

“SGI understands the significance of inter-processor communications, power, density and usability when architecting for exascale. Intel has made the leap towards exaflop computing with the introduction of Intel® Many Integrated Core (MIC) architecture. Future Intel® MIC products will satisfy all four of these priorities, especially with their expected ten times increase in compute density coupled with their familiar X86 programming environment.” –Dr. Eng Lim Goh, SGI CTO

Claire CatesPrincipal Developer, SAS Institute Inc.

We improved the performance of the latest run 3 fold. We wouldn't have found the problem without something like Intel® VTune™ Amplifier XE.



Intel® VTune™ Amplifier XE Tune Applications for Scalable Multicore Performance

• Fast, Accurate Performance Profiles– Hotspot (Statistical call tree)– Hardware-Event Based Sampling

• Thread Profiling– Visualize thread interactions on timeline– Balance workloads

• Easy set-up– Pre-defined performance profiles– Use a normal production build

• Compatible– Microsoft, GCC, Intel compilers– C/C++, Fortran, Assembly, .NET– Latest Intel® processors

and compatible processors1

• Find Answers Fast– Filter extraneous data– View results on the source / assembly– Event multiplexing

• Windows or Linux– Visual Studio Integration (Windows)– Standalone user i/f and command line– 32 and 64-bit

1 IA32 and Intel® 64 architectures. Many features work with compatible processors. Event based sampling requires a genuine Intel® Processor.

Optimization Notice

Intel’s compilers 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 SSE2®, SSE3, and 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. Certain optimizations not specific to Intel microarchitecture are reserved for

Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information

OpenMP • Need high level abstractions (instead of low level native threads) • Look to use traditional execution patterns and utilize standards

OpenCL • Use specifically when heterogeneous support is required (CPU+GEN/NVIDIA/ATI support)• Need low level control/API and interoperability w/ OpenGL and DX• Requires deep expertise and advanced knowledge

C++ Intel CilkTM

Plus• Language extensions for task and data parallelism. • Simple yet powerful compiler based solution with a lower overhead

PBB (TBB) • Widely used C++ template library for task parallelism.• Contains a rich feature set for general purpose parallelism

OpenCL • Can be used in API level, but kernel needs to be implemented in C
