The ratio of the SUV from two different regions within the same PET image (i.e. from a target and a reference region) is commonly abbreviated as SUVR. An example is the ratio of regional Pittsburgh compound B PET signal intensity to the average of a wider region. For the SUVR, the injected activity, the body weight and the volume to mass conversion factor that are all part of the SUV calculation, cancel:
tuned and ktune. tuned is a daemon that monitors the use of system components and dynamically tunes system settings based on that monitoring information. Dynamic tuning accounts for the way that various system components are used differently throughout the uptime for any given system.
Furthermore, to be a real master, the node must run a daemon called the Job Tracker daemon. The slave, to be able to do its work, must run another daemon, called the Tasktracker daemon. The master does not divide all the work beforehand, but has an algorithm on how to assign the next portion of the work. Thus, no time is spent up front, and the job can begin right away. This division of labor, how much to give to the next Tasktracker, is called split, and you have control over it.
