Part 4 of 4 (Innovation Changers)
Writing the sample code for this post I was amazed myself to see how simple it was to reach over 20 times performance improvement with so little effort.
What is performance per Watt?
THE GORY DETAILS
Let’s continue from where we left off last time. Let’s figure out the why of the equation,
P = C * V^2 * (a * f)
[Warning: Math and physics alert! Math and physics alert!] I think that you've all seen this equation before:P = a * C * V2 * f
This relationship between P-states, voltage and frequency is well and good, but how does this relate to power management? Power is literally, energy usage per unit of time.
What is a P-state?
Right now we have 4 PC laptops in our house; 5 if you count the iPad 2 being a ‘personal computing’ device.
OpenSimulator Virtual World Server Case Study (Part 3): Virtual World Server Power Savings by Dynamic Physics TuningUse of virtual worlds for training, entertainment, and collaboration is growing. Intel Labs has been researching the scalability of virtual worlds. This series explores some of the design, performance, and execution features of virtual world servers.
