Optimization Notice
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
regarding the specific instruction sets covered by this notice.

ISV Guidance: Tools for Parallelism
App Tool Description
Distributed MPI • Multi-fabric message passing library used for making applications
perform better on IA-based clusters.
Fortran OpenMP • Need high level abstractions (instead of low level native threads)
• Look to use traditional execution patterns and utilize standards
C Intel CilkTM • Language extensions for task and data parallelism
Plus • Simple yet powerful compiler based solution with a lower overhead
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 • Language extensions for task and data parallelism.
Plus • 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

Select from a variety of powerful tools to aid parallelism
Although most tools can be used for multiple languages, Intel recommendations are listed above.
