DEVICE AND METHOD FOR DEBUGGING PARALLEL DECENTRALIZED SYSTEMS

摘要

PROBLEM TO BE SOLVED: To actualize an efficient debugging in the debugging for processes operating on parallel decentralized systems. SOLUTION: In a task 1-1 in a process, a normal trace gathering means 3-1 records identification information of a task number and process contents in a trace file 6-1, a message transmitting means 4-1 embeds a pair of a message number generated by a message number generating means 2-1 and the current task number in a message, sends the pair and also records it in the trace file 6-1, a message receiving means 5-1 records a set of the task number, the message number of a received message and a transmission origin task number in the trace file 6-1 and a trace extracting means 80 specifies the task number and the number of a sent message in the designated task and extracts the trace of the tasks coincident with the received message numbers and the transmission origin task numbers from among the traces.
