Abstract: An information processing apparatus includes: a first calculator and a second calculator being coupled to each other via a bus, and each making a memory access, designating a logical address; a first memory being coupled to the first calculator; and a second memory being coupled to the second calculator and being accessed from the first calculator via the bus, wherein the first memory determines, based on a time from issue of a request for the memory access to response to the request, whether a memory having a physical address associated with the logical address is the first memory or the second memory. With this configuration, it is possible to specify whether a memory being accessed using a logical address is a local memory or a remote memory.

Abstract: An information processing apparatus includes a transmission unit, a reception unit and a processor. The transmission unit transmits a packet. The reception unit receives a packet. The processor measures a load ratio, which is a usage rate of a band between the transmission unit and the reception unit, when the transmission unit is transmitting the packet to the reception unit. Then, the processor sequentially adjusts a plurality of parameters whose changes insetting lead to changes in the load ratio, in descending order of influence on an increase/decrease in the load ratio in such a manner that the measured load ratio becomes closer to a determined load ratio.
