To obtain results for the pre-determined sample problem sizes on a given system, type:
To run the software for other problem sizes, see the extended help included with the program. You can view extended help by running the program executable with the -e option:
The pre-defined data input files lininput_xeon32, lininput_xeon64, are examples. Different systems have different numbers of processors or amounts of memory and therefore require new input files. The extended help can give insight into proper ways to change the sample input files.
Each input file requires the following minimum amount of memory:
lininput_xeon32 2 GB
lininput_xeon64 16 GB
If the system has less memory than the above sample data input requires, you may need to edit or create your own data input files, as explained in the extended help.
The Intel Optimized LINPACK Benchmark determines the optimal number of OpenMP threads to use. To run a different number, you can set the OMP_NUM_THREADS or MKL_NUM_THREADS environment variable inside a sample script. If you run the Intel Optimized LINPACK Benchmark without setting the number of threads, it defaults to the number of physical cores.
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.
