Abstract: According to one embodiment, a valid-cluster search module searches valid clusters included in first blocks, in each of channels, for compaction. A read command generator generates read commands used to read, in parallel, valid clusters to be migrated to a second block. The valid clusters searched in each of the channels comprise the valid clusters to be migrated. The valid clusters to be migrated correspond to a number of clusters simultaneously written to the second block and to a second number of channels in a first number of channels. A determination module determines the second number of channels corresponding to read commands to be generated next based on a situation of issuance of the read commands.

Abstract: According to one embodiment, a storage controller includes a condition storage, a determination module, a wear-leveling block retainer, and a data transfer controller. The condition storage is provided in a storage including a plurality of blocks, and stores block condition information including at least one of erasure time information indicating when data is erased last time and erasure count information indicating the number of times data is erased. The determination module determines whether there is a block that requires wear leveling based on the block condition information. The wear-leveling block retainer retains block identification information that identifies a block determined to require wear leveling. The data transfer controller performs compaction to transfer data stored in blocks of the storage for collecting the data in a block, and, when the block identification information is retained, transfers data stored in the block identified by the block identification information.

Abstract: A log in which a series of events occurred as a result of the execution of the target program has been recorded is inputted. A plurality of partial logs are created from the inputted log. These partial logs are normalized on the basis of the master log serving as a normalization reference. The feature value representing the degree of feature of the occurrence and nonoccurrence of an event is calculated for each of the normalized logs on the basis of the normalized logs for the remaining partial logs. In a combination of a specific partial log and another partial log, the similarity between these partial logs is calculated by performing an operation on the basis of the feature values. For example, a combination of the specific partial log and the partial log with the highest similarity is displayed.
