Klaus-Dieter Lange is SPECtacular

Another SPECtacular award from the SPEC annual meeting: Klaus Lange (HP) has become a valuable conduit across different levels of the organization and across benchmark subcommittees, by virtue of becoming indispensable in all of them. Though Klaus is an experienced "SPEC hand" he never forgot what he faced as a newcomer, and took it on himself to organize a new member orientation program to help new institutions integrate into SPEC more easily and effectively. As chair of the SPECpower committee Klaus delivered the industry's first energy efficiency benchmark, and leads the committee in aiding other groups as they add energy metrics to a wide range of benchmarks. These groups include many SPEC committees as well as other industry consortia. As HP's representative on the OSG steering committee Klaus has earned respect for his opinions with his diligence and fair mindedness. As a member of the Board of Directors he is often the first to step up to volunteer for important projects, as well as exercising sound judgment in conducting SPEC's business operations.

SPEC awards, power performance

More 2009 SPECtacular awards. The SPECpower committee has been busy. They released version 1.10 of the SPECpower_ssj2008 benchmark as a no-cost upgrade to existing licensees. It adds support for measurement of multi-node (blade) servers, improves usability, and adds a graphical display of power data during benchmark execution. Review and publication of benchmark results continues apace, with a spirited competition for first place, and with ever more power analyzers accepted for testing, and more test labs qualified for independent publication. They have also been assisting several other benchmark committees inside SPEC, and other industry standard benchmark organizations, to implement energy measurement for their benchmarks. SPECpower is more than just a benchmark; it is a methodology, and the methodology is modified and expanded as necessary over time to accommodate energy measurements for all the different workloads which are relevant to the real world in those market segments. In alphabetical order SPEC recognizes:

  • Chris Boire (Sun Microsystems) – As release manager he coordinated and integrated development activities to keep the deliverables on schedule.

  • David Schmidt (HP) – He created stand-alone and network integrated tools for automated results checking to help insure that results submissions are correct and complete.

  • Greg Darnell (Dell) – Author of the PTDaemon, he helped many other groups get started measuring power for their benchmarks. He helps out with whatever needs to be done, technical or organizational.

  • Hansfried Block (Fujitsu Technology Solutions) - He automated the process of determining power analyzer precision, handled the acceptance of several new power analyzers, and was instrumental in getting multi-channel analyzers accepted.

  • Harry Li (Intel) – He was primary developer of the Visual Activity Monitor, giving an unique view of the system's activity.

  • Jeremy Arnold (IBM) – If I tried to recount all the accomplishments Jeremy was cited for I'd probably run into some internal blog size limit. Suffice it to say he is a primary developer on many parts of the code, who never turns down a plea for help, and who is never satisfied until the entire benchmark package is right.

  • Karl Huppler (IBM) – As primary author/editor of the Power and Performance Methodology, he organized the document to capture deep technical consensus in the committee, and made it readable and understandable for people new to the field.

  • Matthew Galloway (HP) – He designed the control software to drive multiple JVMs, enabling multi node (blade) testing.

  • An engineer (AMD) – Who created and maintained much of the web content explaining the benchmark and methodology to the public.

SPEC awards, graphics

More 2009 SPECtacular awards. Sometimes even success doesn't succeed, at first. SPEC developed a workstation energy consumption benchmark, and a lot of people worked extra hard to deliver it in time for EPA to consider using it in the Energy Star program which is being extended beyond PC's to also include workstations, servers, thin clients, and storage. Although EPA decided not to use our test for the workstation program at this time, the work is still important and I am confident it will be used in some way. A graphics processor can easily use more energy than a CPU, especially a high performance accelerated 3D processor. For their exceptional work in producing this benchmark I thank David Reiner of AMD, Joerg Grosshennig of Fujitsu Technology Solutions, Paul Besl of Intel, and an engineer from NVIDIA.

energy efficiency and virtualization

There's an interesting posting on ZDnet from LinuxWorld about workload consolidation and virtualilzation to reduce power consumption, with some pros and cons. Then looking at other postings by George Ou I saw this idea for secure anonymous Wifi hotspot access. Maybe we'd all better read Ou's blog before our usernames and passwords end up posted on Defcon's wall of sheep.
