MEMORY ALLOCATION PROGRAM, MEMORY ALLOCATION METHOD AND MEMORY ALLOCATION DEVICE

摘要

To enable efficient allocation of a cache area.SOLUTION: A memory allocation device 101 acquires log information concerning an access to target data for allocation of a cache area. The memory allocation device 101 calculates an index value showing an improvement degree of a cache error corresponding to an increase in the cache area for each predetermined time interval on the basis of the acquired log information. The memory allocation device 101 identifies improvement target time of the cache error on the basis of the index value for each calculated time interval. The memory allocation device 101 calculates the size of a cache area allocated to target data on the basis of log information concerning an access to the target data at the same timing as the identified improvement target timing. The memory allocation device 101 develops a memory allocation plan for allocating the cache area of the calculated size to the target data earlier than the improvement target timing.SELECTED DRAWING: Figure 1
