New version of
SPEC's PTDaemon now available
SPEC has released a new
version of SPEC’s PTDaemon which is now available to all licensees
of SPECpower_ssj2008 and SPECweb2009. The updated version 1.3.9
adds
support for the Yokogawa WT500 power analyzer, an update
for the Chroma 66202 power analyzer, and
most importantly some additional checking to
help avoid power analyzer configuration problems which could lead to
invalid runs. Please see http://www.spec.org/power_ssj2008/docs/device-list.html
for the latest accepted device list along with the update
files
and instructions for updating your current PTDaemon binary
to the latest version.

SPEC announces
blade server support with the release of SPECpower_ssj2008 v1.10
This release of SPECpower_ssj2008 v1.10 adds several new capabilities
including: support for measuring multi-node (blade) servers,
further automation of power measurement, support for multiple power
analyzers, and a visual activity monitor which provides real-time
graphic display of data collected while running the benchmark.
This update will be provided on CD at no charge to existing licensees
of the software. For a detailed description of changes in this
release, please see the README file.
Results from v1.10 are comparable to results from v1.00 and v1.01 for
single node server comparisons. Licensees are strongly encouraged
to immediately start using version 1.10 for submissions due to its
automated calculation of measurement uncertainty. The last day
for v1.01 submissions is June 30th, 2009 for inclusion in the July
1st-14th review cycle. All submissions on and after July 1st,
2009 will require the use of version 1.10.
SPECpower_ssj2008 is the first industry-standard SPEC benchmark that
evaluates the power and performance characteristics of volume server
class and multi-node class computers. With
SPECpower_ssj2008, SPEC is defining server
power measurement standards in the same way we have done for
performance.
The drive to create the power and performance benchmark comes from
the recognition that the IT industry, computer manufacturers, and
governments are increasingly concerned with the energy use of
servers. Currently, many vendors report some energy efficiency
figures, but these are often not directly comparable due to differences
in workload, configuration, test environment, etc. Development of
this benchmark provides a means to measure power (at the AC input) in
conjunction with a performance metric. This should help IT
managers to consider power characteristics along with other selection
criteria to increase the efficiency of data centers.
The initial benchmark addresses only one subset of server workloads:
the performance of server side Java. It exercises the CPUs,
caches, memory hierarchy and the scalability of shared memory
processors (SMPs) as well as the implementations of the JVM (Java
Virtual Machine), JIT (Just-In-Time) compiler, garbage collection,
threads and some aspects of the operating system. The benchmark
runs on a wide variety of operating systems and hardware architectures
and should not require extensive client or storage
infrastructure. Additional workloads are planned.
Since this is the first power-performance
benchmark, a general methodology
(PDF)
for power
measurement has been documented to assist other benchmark developers
interested in measuring power and in the hopes of establishing a common
set of practices in this new area of benchmarking.
