Updated PTDaemon Interface Meets Today's Industry Needs

By Klaus-Dieter Lange, SPECpower Committee Chair

I'm pleased to announce a recent update to the PTDaemon interface. SPEC benchmarks play an increasingly important role in energy efficiency and sustainability initiatives because they enable computer vendors, enterprises, and government entities to accurately measure energy consumption by computing systems and data centers. The PTDaemon interface makes it easier for SPEC benchmarks to measure power and temperature by providing a common TCP/IP-based interface that can be integrated into different benchmark harnesses. This allows power measurement devices to be automatically incorporated into performance evaluation software and eliminates the need for users to understand and adapt to different power analyzer interface protocols and behaviors.

The SPECapc Benchmark — A User's Story

By Jessica Heerboth, SPECapc Committee Chair

Ashley, a college sophomore majoring in graphics and design, specializes in 3D modeling. Her final project at the end of her freshman year was to create and animate a 3D game character that exhibited some lifelike characteristics when running, jumping and throwing.

Her modeling tool of choice was Autodesk Maya 2024, the latest version of the popular 3D software that both professionals and enthusiasts use to create realistic characters and blockbuster-worthy effects. However, Ashley's animation process required her to frequently make small tweaks to a frame and then re-render the animation to see how that small tweak looked before making the next tweak. Unfortunately, the laptop computer she'd used since high school wasn't equipped with powerful enough hardware to support fast rendering of the animation, forcing her to sit idly for 10 or 15 minutes while each re-rendering finished – amounting to several hours of wasted time each day.
