Abstract: PROBLEM TO BE SOLVED: To provide a device, a program product, and a method which make effective the resetting of a processor in multiprocessor environment by using a memory access interruption. SOLUTION: A source processor is allowed to start resetting a target processor by generating a reset request and a memory access interruption to the target processor. The target processor is constituted so as to detect the presence of a held reset request, specially, in the processing of a memory access interruption, and consequently the target process performs resetting operation in response to the detection of a request thereby.

Abstract: PROBLEM TO BE SOLVED: To shorten the generation time of a partition manager by managing the use of computer system resources by multiple logical sections and including the partition manager including one call of an operating system present in a previously selected logical section. SOLUTION: A main memory 120 includes the partition manager 122 and manages a primary section 124 and one or more secondary sections 126, which are all logical sections. The primary section 124 includes an operating system 125 and the secondary sections 126 include an operating system 127. The partition manager 122 includes an interface 123 for the operating system 125 in the primary section 124. Thus, the partition manager 122 implements its section managing function by using a code which is already present in the operating system 125 instead of copying the code.
