Abstract
PURPOSE: To make a timer coincidence among computers, by using a common memory among computers and an interruption input and output among computers.
CONSTITUTION: Six standard time input programs in NO.1 master computer 1 receive periodically time from external timepiece 5. On arrival of the input, corrections of its own timer are made and the time is set in memory 2 as time data 11. Next, interruption 12 is sent to other computers 1. Then, NO.2W(n) computers 1 accept this interruption 12 by time set program 7. This program fetches data 11 in common memory 2 and sets it to its own timer. Consequently, a timer coincidence among computers can be made with only the time delay of the operation time of the program and the reception of the interruption.
