Abstract: Various embodiments intelligently cache data in distributed clustered file systems. In one embodiment, a set of file system clusters from a plurality of file system clusters being accessed by an information processing system is identified. The information processing system resides within one of the plurality of file system clusters and provides a user client with access to a plurality of files stored within the plurality of file system clusters. One or more file sets being accessed by the information processing system are identified for each of the set of file system clusters that have been identified. A set of data access information comprising at least an identifier associated with each of the set of file system clusters and an identifier associated with each of the one or more file sets is generated. The set of data access information is then stored.

Abstract: Embodiments for rendering content by a processor are provided. A request to render content is received. A rendering browser to render the content on a computing device is selected from a plurality of rendering browsers. The selecting of the rendering browser is based on security information associated with at least one of the content and the plurality of rendering browsers.

Abstract: In accordance with one embodiment of the present description, a logical file unit containing a set of data stored in cache or other memory and mapped by a reference pointer to a physical file unit in a storage, may be overwritten with new data in the memory without first read/write copying the data in memory to a new logical file unit in the file system. Instead, the original physical file unit of data in the storage is preserved and the original reference pointer for the original physical file unit of data may be used to map a new logical file unit in the file system to the original physical file unit storing the original set of data. Other aspects are described.
