Using the Intel LINPACK Benchmark to stress the hardware

Via http://kb.fusionio.com/KB/a62/using-linpack-benchmark-to-stress-test-your-system.aspx

• Download Intel LINPACK Benchmark

• Reboot to the terminal (don't start X), unload unneeded drivers and stop unneeded applications

• Go into the linpack_X.Y.Z/benchmarks/linpack directory

• Compute the job size:

Using a python script
>>> import commands
>>> import math
>>> math.floor(math.sqrt((float(commands.getoutput("free -b|grep Mem|awk '{print $2}'"))-1073741824)/8)/16)*16+8

• Creat a new lininput_xeon64 input file using the number XXXXX calculated above:

Sample Intel(R) LINPACK data file (lininput_xeon64)
Intel(R) LINPACK data
1 # number of tests
XXXXX # problem sizes
XXXXX # leading dimensions
1 # times to run a test
4 # alignment values (in KB)

• Run time ./runme_xeon64

• Adjust problem size and leading dimensions if needed

• Compute the number of passes needed for one hour run and change the 'times to run a test' entry

• Run time ./runme_xeon64 and check lin_xeon64.txt
