A molding machine for providing flaskless molds comprising a drag flask and a cope flask is provided with a core setter for placing cores in upwardly facing cavities of a mold located in the drag flask. Besides, an SSL session is constructed between an SSL 2002 and an SSL 3002, and upon completing construction of the session, a public key and a secret key are sent by means of an Ethernet frame from a processing speed acceleration engine control to a processing speed acceleration engine. The accessed data are used to produce the reconstruction cost estimate. Next, the system triggers a debugging operation based on the content of the performance counter, thereby facilitating debugging of the integrated circuit without probing signal lines within the integrated circuit.
