Abstract:
Apparatus for deriving traces of multiple data streams from a multiprocessor computer system under test to collect sufficient data from such streams in order that steady state data will appear in said streams, and wherein said traces are coordinated by including therein related time stamp data, said apparatus comprising:a plurality of collector computer systems each having, collector means for collecting one of said multiple data streams from said multiprocessor computer system under test, time stamp means for establishing a time stamp signal wherein said time stamp signal continuously and in regular increments is updated from an initial value and provided as a time stamp signal output from said time stamp means, reset means for resetting said time stamp means to produce said initial value upon receipt of an initiation signal, wherein a one of said plurality of collector computer systems is a master and all other of said plurality are slaves and wherein a reset signal line extends from an initiation output register to said reset means of all of said plurality of collector computer systems and wherein said initiation output register produces said initiation signal to be delivered simultaneously to all of said plurality of collector computer systems upon receipt by said master of a start collecting signal.
