  • 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 shell:
>>> 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:
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
