Abstract:
1. A method for synchronizing distributed processors comprising the steps of: establishing a socket-connection between at least two processors; determining a roundtrip delay; determining a roundtrip-delay threshold; determining a current round-trip delay and an offset; adding the current round-trip delay to a list of roundtrip delays; determining a new roundtrip-delay threshold; determining whether the current roundtrip delay is greater than the new roundtrip-delay threshold; determining whether a desired number of round-trip delays have been determined upon determining the current roundtrip delay to be greater than the new roundtrip-delay threshold; and determining whether the offset is greater than an offset threshold, adjusting a clock according to whether the offset is greater than the offset threshold and determining a linear regression upon determining that the current roundtrip delay is not greater than the new roundtrip-delay threshold.
