摘要:
An information processing apparatus includes: an arithmetic operation unit configured to perform an arithmetic operation using an arithmetic operation target and repeat the arithmetic operation by using a calculated arithmetic operation result; a ratio calculation unit configured to obtain a ratio of the number of elements, of the number of elements included in the arithmetic operation result, included in an expressible range as a predetermined-bit fixed point; and an arithmetic operation control unit configured to make the arithmetic operation unit perform the arithmetic operation by using the predetermined-bit fixed point based on the ratio calculated by the ratio calculation unit.

摘要:
An information processing apparatus (10, 20) that mounts a first and second system boards (SB#0, SB#1) includes a virtualization control unit (13, 21) that controls a virtual machine for virtualizing hardware resources. The SB#0 includes a memory (14c, 22) that stores a command line (14d, 22a), resource information (14f, 22d), and management information (14e, 22c). The SB#1 includes a memory (15c, 32) that stores a command line (15d, 32a) and resource information (15e, 32b). The command line is executed by the virtualization control unit (13, 21). The resource information (14f, 15e, 22d, 32d) is data used by each system board (SB#0, SB#1) from among data used when the virtualization control unit (13, 21) operates. The management information (14e, 22c) is data commonly shared by each system board (SB#0, SB#1) and used by the virtualization control unit (13, 21). A command line (14d, 15d, 22a, 32a) and resource information (14f, 15e, 22d, 32d) are used when the virtualization control unit (13, 21) operates and information on the hardware resources (14f, 15e, 22d, 32d) included in the corresponding SB (SB#0, SB#1). Each SB (SB#0, SB#1) executes the command line (14d, 15d, 22a, 32a) and refers to the information stored in the memory (14c, 15c, 22, 32) in SBs (SB#0, SB#1).
