Hi Dave. > Assuming your system specification allows for up to 10 ms measurement > error over two seconds, your script can result in a maximum frequency > error of 5000 PPM. Golly.
With 10ms measurement error, we would never be able to fulfil the requirement of less than 10ms offset between the blades. ;-( However, the blades are communicating with each other via a gigabit ethernet backplane. The poll delay is usually less than 150us. And to cope with single outliers, I use '-p 8' in the script. In addition, the script uses the server timestamp information to calculate the duration of the measurement period to be independent of the potentionally hight error of the local clock. And I anyway have to trust the server. Bye Juergen _______________________________________________ questions mailing list [email protected] https://lists.ntp.isc.org/mailman/listinfo/questions
