By far the largest number of support requests we get for Granola Personal are users who have been told they do not have CPU power management enabled, asking instructions for how to enable it so they can begin to save energy for free. This feedback loop is set up by this window, which gets displayed if Granola Personal detects that the system does not have DVFS (one of the technologies behind CPU power management):
Because Granola Enterprise doesn’t include a graphical display on the individual machines, and because deployment of the Granola Enterprise clients often happens without an administrator physically accessing the machine at all, it was previously difficult to determine whether DVFS was available on those machines or not. You could either infer the capabilities by looking at the data on the dash or check the logfiles on the machine itself; both of these solutions are less than optimal.
Today we have rolled out a new feature to Insight, allowing you to determine which machines have DVFS and which don’t at a single glance. You can also sort your list of machines by DVFS capability, so it’s easy to determine which machines might need a quick look at the BIOS in order to get the best energy efficiency. And of course, once you’ve enabled DVFS, you can then use Power Steering or Power Tuning to optimize the power of your systems while they are running.
Here is a shot of the new column, in the Groups view of the Granola Dash (click for a larger version):
Machines that haven’t checked in yet will be blank, machines with DVFS will say ‘yes’ like sledgewand in the image above, and machines without DVFS will simply and eloquently say ‘no’.
