Abstract
An apparatus for controlling a command retry widens an applied range of a retry function in an information processor for executing a program under pipeline control and aiding reliability, availability and serviceability of the information processor. The command retry control apparatus translates an instruction contained in the program into commands in a processable form and executes the processing on a command basis. The command retry control apparatus determines, if an error occurs during the execution of the command, whether or not an operand value is a normal value and executes, when the operand value is the normal value, a command retry by stopping inputting a next command. The command retry control apparatus continues the processing by resuming the inputting of the next command when normally finishing the command retry. If the error reoccurs in the middle of the command retry, the command retry control apparatus decides that the command is unexecutable and notifies a management system of the occurrence of the error.
