SPECpower_ssj2008 v1.01 - Release Details - readme_1.01.txt - 05/08/2008
------------------------------------------------------------------------

SPECpower_ssj2008 v1.01 is a point release which fixes some of the
issues in the initial release and also adds a few new features not
present in previous releases. Included in this release are also a couple
of changes to the Run and Reporting Rules and the supporting
documentation, neither of which would affect the previously submitted
results or the comparability of results in this benchmark.

Code changes:
 o ssj and director
   o added support for multiple power analyzers and temperature sensors
     (results with multiple power analyzers will be marked invalid for
     this release)
   o linked all validator checks to the correct run rules sections
   o moved to use simple ASCII for text report
   o cores/chip output in "CPUs enabled" field states now core/chip when
     core value is 1
   o Added voltage/current range information to report
   o Added handler for missing temperature data
   o changed the director to report the right loadlevel to CCS after
     "active idle"
   o Added voltage/current range and input connection information to
     report
   o Changed CCS/PTD version warnings into validity errors
   o changed checksum to ignore changes below the -SUBMIT-
   o Added the acceptance of a 3-part version numbers for PTD and CCS
   o Marked multi-analyzer results invalid
   o Clarified description of input.load_level.target_max_throughput
   o Added 220V to list of line standard voltages
   o Updated compliant PTD and CCS version numbers (PTD 1.3.1 and
     CCS 1.1.3)
   o Make SPECpower_ssj_config.props pass new submission tool checks

 o ptd
   o added Xitron 280x as an accepted measurement device 
   o added "Mark" capabilities so different benchmark stages can be
     identified in logged output 
   o added date string to logged output 
   o added mutex protection to data logging & reporting to fix race 
   o marked Instek GPM-8212 amp readings over 10A as invalid due to
     crest factor specs 
   o added support for serial ports above COM9 in Windows 
   o added experimental support for additional power analyzer 
   o general code improvements

 o ccs
   o added multiple data source definition feature
   o added new configuration properties
   o general code improvements

Design Document enhancements:
   o Additions to Overview: Component Numbering

Run and Reporting Rules enhancements:
 o Additions to Section 3.3.5.1 Power Analyzer and Temperature Sensor 
   o Power analyzer voltage range 
   o Power analyzer current range 
   o Power analyzer input connections 

 o Modification to Section 13.2 Power Analyzer Specifications 
   o Logging - The analyzer must have an interface that allows its
     measurements to be read by the PTDaemon. The reading rate supported
     by the analyzer must be at least 1 set of measurements per second,
     where set is defined as watts and at least 2 of the following
     readings: volts, amps and power factor. The data averaging interval
     of the analyzer must be either 1 (preferred) or 2 times the reading
     interval. "Data averaging interval" is defined as the time period
     over which all samples captured by the high-speed sampling
     electronics of the analyzer are averaged to provide the measurement
     set. 

 o Modification to Section 2.8 Line Voltage Source 
   o The preferred Line Voltage source used for measurements is the main
     AC power as provided by local utility companies. Power generated
     from other sources often has unwanted harmonics which are incapable
     of being measured correctly by many power analyzers, and thus would
     generate inaccurate results. 
     The Line Voltage Source needs to meet the following
     characteristics:
       Frequency: (60Hz, 50Hz) ± 1% 
       Voltage: (120V, 110V, 100V, 208V, 220V, 230V) ± 5% 
     The usage of an uninterruptible power source (UPS) as the line
     voltage source is allowed, but the voltage output must be a pure
     sine-wave. For placement of the UPS, see 2.13.1. This usage must be
     specified in the Note-section of the FDR. If an unlisted line
     voltage source is used, a reference to the standard is necessary.
     For situations in which the appropriate voltages are not provided
     by local utility companies (e.g. measuring a server in the United
     States which is configured for European markets, or measuring a
     server in a location where the local utility line voltage does not
     meet the required characteristics), an AC power source may be used,
     and the power source must be specified in the notes section of the 
     disclosure report. In such situation the following requirements
     must be met, and the relevant measurements or power source
     specifications disclosed in the notes section of the disclosure
     report: 
     Total Harmonic Distortion of source voltage (loaded), based on IEC
     standards: < 5% 
     The AC Power Source needs to meet the frequency and voltage
     characteristics previously listed in this section. The AC Power
     Source must not manipulate its output in a way that would alter the
     power measurements compared to a measurement made using a compliant
     line voltage source without the power source. The intent is that
     the AC power source not interfere with measurements such as power
     factor by trying to adjust its output power to improve the power
     factor of the load.

Happy Benchmarking!
