Node Power Consumption

Testing Power Consumption:

  1. Connect the multimeter power strip to a UPS.
  2. Connect a second power strip to the multimeter strip.
  3. Connect the multimeter serial cable to a node other than those being tested.

Running The Multimeter Utility:

  1. Copy the multimeter-0.0.5.tar.gz file from /net/m001/root/
  2. Run tar zxvf multimeter-0.0.5.tar.gz to untar the file.
  3. Now make it by running: cd multimeter-0.0.5.tar.gz && make
  4. To test the output run the script: ./multimeter -6 -l -i /dev/ttyS0
      *Output should be displayed immediatly on the screeen. If not then switch the /dev/ttyS0 to /dev/ttyS1.

Setup Loopheat.sh and Read_disk.sh

  1. Copy read_disk.sh and loopheat.sh from /net/m001/root/
  2. Log in as root on the machine you will be using to monitor the multimeter.
    • On virtual console 1 input ./multimeter -6 -l -i /dev/ttyS0 > /root/file_name.log but do not press ENTER yet.
    • On virtual console 2 input ./loopheat.sh <start> <end> /net/m001/root/kflasch/heat/heat 20 200 but do not press ENTER yet.
    • On virtual console 3 input ./read_disk.sh <start> <end> /data 20 200 but do not press ENTER yet.
    • On virtual console 4 input ./read_disk.sh <start> <end> /localscratch2 20 200 but do not press ENTER yet.
    • On virtual console 5 input ./read_disk.sh <start> <end> /datc 20 200 but do not press ENTER yet.

Running A Test.

  1. Switch to virtual consol 1 and press enter.
  2. On the count of 10 switch to virtual consol 2 - 5 pressing ENTER in each.
  3. Allow the tests to complete.
  4. Once all tests have finished switch to virtual console 1 and press C after 20 seconds have passed.
