I have released a new test version of 4.2.4p6 with numerous Windows- specific improvements compared to the baseline 4.2.4p6. Since my last release, the most significant change is to read the processor cycle counter using the RDTSC instruction directly when it is equivalent to QueryPerformanceCounter. When it is not equivalent, ntpd is allowed to roam freely across all logical processors once again.
I've also made small changes to the counter frequency tuning code to balance observation time (longer is better quality, to a point, but also means it takes longer to effect the counter frequency compensation after startup). The counter frequency tuning messages have been further quieted to once every 8 hours after the initial compensation is done. http://davehart.net/refclock/ has binaries, debug binaries, symbols, and source, most people will want: http://davehart.net/ntp/refclock/ntp-4.2.4p6-DLH-QPC-20090310-bin.zip http://tinyurl.com/cz8kk4 Cheers, Dave Hart _______________________________________________ questions mailing list questions@lists.ntp.org https://lists.ntp.org/mailman/listinfo/questions
