摘要： A spin transistor having wide ON/OFF operation margin and producing less noise is provided. The spin transistor includes a substrate having a channel, a source, a drain and a gate formed on the substrate. The source and the drain are formed to have magnetization directions perpendicular to the length direction of the channel. The ON/OFF operations of the spin transistor can be controlled by generating a spin-orbit coupling induced magnetic field to have a direction parallel or anti-parallel to the magnetization directions of the source and the drain.

摘要： A system and method in a data processing system for recovering data in a file system. A request to modify a data block in the file system is detected. In response to detecting the request to modify the data block, metadata describing the data block in the file system is written in a log. In response to detecting an error during the writing of the metadata, an error counter is incremented. Finally, in response to a request to recover the data in the file system, the metadata is read only if the error counter is less than or equal to a predetermined value.

摘要： An extended attribute data page includes extended attribute information about a number of files. The page is divided into areas, each area corresponding to a different file. A given area is further divided into a number of lines containing information about the extended attribute data. Areas include bitmaps indicating available space in the data space and address information for addressing off-page data areas. A directory is included of data types stored in the data area, and additional lines store extended attribute data. The extended attribute directory maintains a list of data types currently stored and related information. Including availability information about each line along with addresses to areas storing extended attribute data enables the extended attribute manager to efficiently determine where to place extended attribute data, mark deleted lines as being available, retrieve data being requested by a process, and modify the contents of a given extended attribute data type.

摘要： A method and apparatus for a multiple concurrent writer file system are provided. With the method and apparatus, the metadata of a file includes a read lock, a write lock and a concurrent writer flag. If the concurrent writer flag is set, the file allows for multiple writers. That is, multiple processes may write to the same block of data within the file at approximately the same time as long as they are not changing the allocation of the block of data, i.e. either allocating the block, deallocating the block of data, or changing the size of the block of data. Multiple writers is facilitated by allowing processes performing write operations that do not require or result in a change to the allocation of data blocks in a file to use the read lock of a file rather than the write lock of the file. Software serialization or integrity mechanisms may be used to govern the manner by which these concurrent write operations have their results reflected in the file structure. Those processes performing write operations that do require or result in a change in the allocation of data blocks in a file must still acquire the write lock before performing their operation.
摘要翻译：提供了一种用于多并发写入器文件系统的方法和装置。利用该方法和装置，文件的元数据包括读锁定，写锁定和并发写入器标志。如果并发写入器标志被设置，该文件允许多个写入器。也就是说，多个进程可以在大致相同的时间内写入文件中的相同数据块，只要它们不改变数据块的分配，即分配块，取消分配数据块或改变数据块的大小。通过允许执行不需要或导致文件中的数据块的分配的使用文件的读取锁定而不是文件的写入锁定的写入操作来促进多个写入器。可以使用软件序列化或完整性机制来管理这些并发写操作的结果反映在文件结构中的方式。执行需要或导致文件中数据块分配变化的写入操作的那些进程必须在执行它们的操作之前获取写入锁定。

摘要： A method, computer program product and data processing system for accessing extended attributes. An extended attribute descriptor in a dinode may be read to determine if there exists extended attributes associated with a file system object that is associated with the dinode. An extended attribute descriptor points to a dinodex associated with the dinode if there exists an extended attribute associated with the file system object. The dinodex may then be read to retrieve the extended attritbutes stored either inside or outside the dinodex. However, if there is no extended attribute associated with that particular file system object, then the extended attribute descriptor comprises a null value and does not point to a dinodex associated with the dinode.

摘要： A cluster server manages allocation of free blocks to cluster clients performing writes in a clustered file system. The cluster server manages free block allocation with a free block map and an in-flight block map. The free block map is a data structure or hardware structure with data that indicates blocks or extents of the clustered file system that can be allocated to a client for the client to write data. The in-flight block map is a data structure or hardware structure with data that indicates blocks that have been allocated to clients, but remain in-flight. A block remains in-flight until the clustered file system metadata has been updated to reflect a write performed to that block by a client. After a consistency snapshot of the metadata is published to the storage resources, the data at the block will be visible to other nodes of the cluster.

摘要： Maintaining a generation value for each fileset that is distinct from a corresponding fileset manager preserves the independence of nodes while also allowing distributed fileset management. A fileset manager can maintain a value that reflects consistency snapshots for that node (“node generation”) separately from a value that reflects consistency snapshots for a particular fileset (“fileset generation”).

摘要： One embodiment is for using a sparse file as a clone. The method includes creating, by an application associated with a computer system, a snapshot of a file, such as an individual file, a collection of files, file system, directories, and so forth. Further, the method includes requesting, by the application, a clone of that created snapshot. Further still, the method includes generating, by the application, an empty sparse having at least one inode identifying the empty sparse file as the clone and pointing to the snapshot associated with the clone. Thereby, the requested clone is created using the created sparse file, which begins as an empty sparse file.

摘要： Management of a file hierarchy for a clustered file system can be distributed across nodes of the cluster. A cluster file hierarchy is accessed to determine location of a file in response to a request to write to a file. A first node maintains the cluster file hierarchy. It is determined that management of a fileset object, which represents a fileset that includes the file, has been delegated to a second node based, at least in part, on said accessing the cluster file hierarchy. A node file hierarchy maintained by the second node is accessed responsive to determining the delegation. The cluster file hierarchy represents filesets of the clustered file system and the node hierarchy represents a subset of one or more of the filesets. Location of the file is determined based, at least in part, on said accessing the node file hierarchy.
