Sun Microsystems is a multinational vendor of computers, computer software and hardware, and information technology services.
For Solaris threads, a condition variable enables threads to atomically block until a condition is satisfied. The condition is tested under the protection of a mutex lock. When the condition is false, a thread blocks on a condition variable and atomically releases the mutex waiting for the condition to change. When another thread changes the condition, it can signal the associated condition variable to cause one or more waiting threads to wake up, reacquire the mutex, and re-evaluate the condition. Condition variables can be used to synchronize threads in this process and other processes if the variable is allocated in memory that is writable and shared among the cooperating processes and have been initialized for this behavior.
Industry:Computer
Extra bits used by hardware to ensure correct rounding, not accessible by software. For example, IEEE double precision operations use three hidden bits to compute a 56-bit result that is then rounded to 53 bits.
Industry:Computer
A concatenation of XSLT transformations in which the output of one transformation becomes the input of the next.
Industry:Computer
A computer program that enables the automation of a well defined activity by performing a specific well defined task when it detects a predetermined set of conditions.
Industry:Computer
A component that provides services in response to requests; either a servlet or a JSP page.
Industry:Computer
Computer control behavior where a specific operation is begun upon receipt of an indication (signal) that a particular event has occurred. Asynchronous control relies on synchronization mechanisms called locks to coordinate processors. See also mutual exclusion, mutex lock, semaphore lock, single-lock strategy, spin lock.
Industry:Computer
A combination of local memory and processors at each node of the interconnect network topology. Each processor can directly access only a portion of the total memory of the system. Message passing is used to communicate between any two processors, and there is no global, shared memory. Therefore, when a data structure must be shared, the program issues send/receive messages to the process that owns that structure. See also interprocess communication, message passing.
Industry:Computer
A combination of discrete tasks that has a clearly defined beginning and end. A group of tasks that are carried out as part of a process.
Industry:Computer
A collective term for a board and its card cage slot. A physical attachment point describes the software driver and location of the card cage slot. A logical attachment point is an abbreviated name created by the system to see the physical attachment point.
