------------------------------------------------------------------------------------

OS and Application Settings

1) Install Red Hat* Enterprise Linux 6.4 with all packages.

2) Download and install Intel® Optimized LINPACK Linux package v11.0.5.009 or later from http://software.intel.com/en-us/articles/intel-math-kernel-library-linpack-download 

3) Create a directory on the system under test called /linpack.

4) Copy the linpack .tgz file to /linpack directory.  For this example the linpack compressed file is named l_lpk_p_11.0.5.009.tgz.

5) Decompress the linpack .tgz file by typing

tar xvzf l_lpk_p_11.0.5.009.tgz

6) Expand the Make the following changes in the lininput_xeon64:

− Problem size: 90000 120000

− Leading Dimensions: 90000 120000

− Alignment: 11

Invocation

1) Open a terminal window in Red Hat* Enterprise Linux 6.1 in the linpack directory

7) Type “./runme_xeon64”.

Results

Results will appear in lin_xeon64.txt
