Abstract: A Scalable NonZero Indicator (SNZI) object in a concurrent computing application may include a shared data portion (e.g., a counter portion) and a shared nonzero indicator portion, and/or may be an element in a hierarchy of SNZI objects that filters changes in non-root nodes to a root node. SNZI objects may be accessed by software applications through an API that includes a query operation to return the value of the nonzero indicator, and arrive (increment) and depart (decrement) operations. Modifications of the data portion and/or the indicator portion may be performed using atomic read-modify-write type operations. Some SNZI objects may support a reset operation. A shared data object may be set to an intermediate value, or an announce bit may be set, to indicate that a modification is in progress that affects its corresponding indicator value. Another process or thread seeing this indication may “help” complete the modification before proceeding.

Abstract: Methods and apparatuses that maintain birth time for a file system to optimize file update operations are described. The file system can include a plurality of snapshots or clones of data stored in one or more extents of blocks allocated in a storage device. Each extent may be associated with a time stamp according to the birth time. A request may be received from an executable using the file system to update data in a particular extent associated with a particular time stamp. In response, the current birth time in the file system and the particular time stamp may be compared to determine if the particular extent is not shared by more than one of the snapshots. If the particular time stamp is equal to the current birth time, the particular extent may be updated directly without performing an expensive operation to check whether a reference count of the particular extent is equal to one.

A recommendation unit recommends related items to the recommendation target user having features resembling those of the recommendation target item.

Abstract: A network's evolution is characterized by graph evolution rules. A graph, formed by merging multiple graphs representing the multiple snapshots of the network, that represents an evolutionary network is mined to identify evolutional patterns of the network. A pattern is selected from the identified patterns. Graph evolution rules are generated using identified evolutional patterns. The generated graph evolution rules represent the evolutional patterns of the network, the rules indicating that any occurrence of a child pattern of the selected pattern implies a corresponding occurrence of the selected pattern.

Abstract: Concurrent resizing and modification of a first RCU-protected hash table includes allocating a second RCU-protected hash table, populating it by linking each hash bucket of the second hash table to all hash buckets of the first hash table containing elements that hash to the second hash table bucket, and publishing the second hash table. If the modifying comprises insertion, a new element is inserted at the head of a corresponding bucket in the second hash table. If the modifying comprises deletion, then within an RCU read-side critical section: (1) all pointers in hash buckets of the first and second hash tables that reference the element being deleted are removed or redirected, and (2) the element is freed following a grace period that protects reader references to the deleted element. The first table is freed from memory after awaiting a grace period that protects reader references to the first hash table.
