Abstract
Ensuring consistency of data being received by a producer from a collector via a shared memory includes maintaining a time-of-day (TOD) variable, and, by the producer for new data, (1) first setting the TOD variable to an invalid value, (2) next writing the new data into the shared memory with a timestamp, and (3) next setting the TOD variable to a time value corresponding to the timestamp. The method further includes, by the collector for the new data, (1) reading the TOD variable and timestamp and confirming that the TOD variable has a valid time value equal to the timestamp, (2) reading the new data from the shared memory, and (3) confirming validity of the new data by (a) reading the TOD variable again, and (b) confirming that the TOD variable has the same valid time value as in the reading step (1).
