The toolset is basically identical with the HPL 2.0 distribution. There are a few changes that are optionally compiled in and disabled until you specifically request them. These new features are:
ASYOUGO: Provides non-intrusive performance information while runs proceed. There are only a few outputs and this information does not impact performance. This is especially useful because many runs can go for hours without any information.
ASYOUGO2: Provides slightly intrusive additional performance information by intercepting every DGEMM call.
ASYOUGO2_DISPLAY: Displays the performance of all the significant DGEMMs inside the run.
ENDEARLY: Displays a few performance hints and then terminates the run early.
FASTSWAP: Inserts the LAPACK-optimized DLASWP into HPL's code. You can experiment with this to determine best results.
HYBRID: Establishes the Hybrid OpenMP/MPI mode of MP LINPACK, providing the possibility to use threaded Intel(R) Math Kernel Library (Intel(R) MKL) and prebuilt MP LINPACK hybrid libraries.
Use this option only with an Intel compiler and the Intel (R) MPI library version 3.1 or higher. You are also recommended to use the compiler version 10.0 or higher.
Optimization Notice |
---|
The Intel® Math Kernel Library (Intel® MKL) contains functions that are more highly optimized for Intel microprocessors than for other microprocessors. While the functions in Intel® MKL offer optimizations for both Intel and Intel-compatible microprocessors, depending on your code and other factors, you will likely get extra performance on Intel microprocessors. While the paragraph above describes the basic optimization approach for Intel® MKL as a whole, the library may or may not be optimized 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. Intel recommends that you evaluate other library products to determine which best meets your requirements. |
