1. An information processing apparatus, comprising:
a plurality of processing units each having a TLB (Translation Lookaside Buffer), wherein at least one of the plurality of processing units is configured to: acquire, from a TLB information extraction setting file, a designation of the processing unit from which TLB information is to be extracted in the plurality of processing units and a designation of a timing when the TLB information is to be extracted; extract the TLB information from the designated processing unit at the designated timing specified based on the TLB information extraction setting file; inhibit the registered information from being rewritten, by locking an entry contained in the TLB and registered with information; and register a TLB extraction command for extracting the TLB information on a memory accessed by using the locked entry.
