| 20100049718 | Transactional Processing for Clustered File Systems - Systems and methods for transactional processing within a clustered file system wherein user defined transactions operate on data segments of the file system data. The users are provided within an interface for using a transactional mechanism, namely services for opening, writing and rolling-back transactions. A distributed shared memory technology is utilized to facilitate efficient and coherent cache management within the clustered file system based on the granularity of data segments (rather than files). | 02-25-2010 |
| 20100049921 | Distributed Shared Caching for Clustered File Systems - Systems and methods for distributed shared caching in a clustered file system, wherein coordination between the distributed caches, their coherency and concurrency management, are all done based on the granularity of data segments rather than files. As a consequence, this new caching system and method provides enhanced performance in an environment of intensive access patterns to shared files. | 02-25-2010 |
| 20100049922 | DISTRIBUTED SHARED MEMORY - Systems and methods for implementing a distributed shared memory (DSM) in a computer cluster in which an unreliable underlying message passing technology is used, such that the DSM efficiently maintains coherency and reliability. DSM agents residing on different nodes of the cluster process access permission requests of local and remote users on specified data segments via handling procedures, which provide for recovering of lost ownership of a data segment while ensuring exclusive ownership of a data segment among the DSM agents detecting and resolving a no-owner messaging deadlock, pruning of obsolete messages, and recovery of the latest contents of a data segment whose ownership has been lost. | 02-25-2010 |
