SPEC releases new version of PTDaemon

GAINESVILLE, Va., June 6, 2017 -- The Standard Performance Evaluation Corp. (SPEC) has released a new version of PTDaemon, the software that allows power measurement devices to be incorporated into performance evaluation software.

PTDaemon provides a common TCP/IP-based interface that can be integrated into different benchmark harnesses. It runs in the background to offload control of the power analyzer or temperature sensor to a system other than the one under test. Benchmarks using PTDaemon include SPECpower_ssj2008, SPECvirt_sc2013 and the upcoming SPEC CPU2017. PTDaemon is also used in the Server Efficiency Rating Tool (SERT) suite and the Chauffeur WDK.

The latest version of the software, PTDaemon 1.8.1, includes new support for Windows USBTMC using Keysight drivers and the Hioki PW3335 (single channel) power measurement device.

Users of SPECpower_ssj2008 and the SERT suite are encouraged to download and apply the update.

Award-winning paper available

In other server efficiency news, the Autopilot tool created by the SPEC RG Power Working Group won the best demo/poster award at the International Conference on Performance Engineering 2017 (ICPE 2017) in L'Aquila, Italy. Autopilot, a plug-in for the Eclipse IDE, enables fast and easy building and deployment of a workload for testing server efficiency.

A paper describing the tool can be downloaded on the SPEC website.
