An allocator's persistent metadata may be lazily persisted when the enclosing transaction commits. An allocator's metadata may be divided into persistent and nonpersistent portions while the heap may be divided into shared and thread-private superblocks.

Abstract: The presently disclosed subject matter includes a data storage system and method for the purpose of migrating data in a distributed storage system comprising a plurality of separate storage areas.

Abstract: In a hierarchical storage memory (HSM), a file recalled by a specific application is migrated as soon as possible after completion of the application process. Specifically, the effective UID of a specific process is preregistered on an HSM client. After a recall operation is performed on a certain file from the user ID, when there is no access from the UID to the file for a given length of time, the file is migrated. This prevents files premigrated by access from any application other than the specific one from being handled in the same way, resolving a disadvantageous problem caused when these (premigrated) files are not desired to be migrated preferentially.
