The present invention is directed to establishment of a higher level of an assurance value. The condition setting support apparatus executes a statistical information accepting step of accepting statistical information where execution results of a program are stored with respect to each combination between each of multiple first parameter values selected from possible values for the first parameter, and each of multiple second parameter values selected from possible values for the second parameter, and a detecting step of detecting based on the statistical information, a group including at least one of the first parameter values which maximizes the assurance value, out of the multiple first parameter values.

Method and apparatus for setting up runtime conditions

An operation complete signal and a convergence result signal from each processor are transferred to the X-direction interconnection switches, AND of these signals is obtained in switch units in each interconnection switch, the signal is sent out to all the Y-direction interconnection switches through a synchronizing signal relay switch and the like in each relay switch, AND of these signals is obtained in each switch unit in the interconnection switches, and the result thereof is transferred to each processor through each synchronizing signal relay switch. With this, a logical product of an operation complete signal and a logical product of a convergence result signal from all the processors are sent in parallel to all the processors.

Parallel computing system for synchronizing processors by using partial

The entry of a problem describing program is assisted by a database or a display screen. An error in numerical calculation of the input problem describing program is automatically checked. A simulation program which interrupts the execution of a process requsted by a statement in the problem describing program which a user designates as a break point when the simulation program executes the process is automatically generated. At the time of interruption, the execution status of the simulation is diagnosed upon the user's request.
