HowTo test cmserver

Node autodetection, boot of the CM image and OAR node's creation

For node atodetection:

• Actions to perform:

  Be sure that the CMserver is running and available
  Be sure that nodes are configured to boot from LAN
  Launch several nodes at same time

• Checks to perform:

  Check that into the CMwebadmin interface, nodes are recorded with the "unconfigured" tag
  Check that after IPXE discovery the operating system on the disk is booting
  Check the /var/log/apache2/error.log file to detect some web errors
  Check the /var/log/error.log file to detect some DHCP/IPXE/TFTP errors  

Node autodetection with the unconfigured tag

For the CM boot image and OAR node creation:

• Actions to perform:

  Log-in into the CMwebadmin interface and configure node scheduler by editing node settings. You can choose the "Always CM" scheduler. By default, this scheduler is using the Debian Squeeze operating system.
  Launch several nodes at same time

• Checks to be perform:

  Check that the CM image is correctly booting

  Check that nodes are also creating into the OAR database (you can use Monika to check that CPU/CORE feature is available)

OAR access and POV ray demos

To check OAR access you can use the POV ray demos from the main menu of the CMWebadmin interface:

• Actions to perform:

  Execute a POV ray demo from the main menu (the link should look likes to http://yourcmserver/wrapper.php?key=raytracing)
  Launch several nodes in Compute Mode

• Check to perform:

  Check that the demo is running correctly and the image appears
  Check that several nodes are used to compute the image

  Check OAR nodes status with Monika
