Sun Microsystems is a multinational vendor of computers, computer software and hardware, and information technology services.
For Solaris threads, threads scheduled onto a pool of LWPs are called unbound threads. The threads library invokes and assigns LWPs to execute runnable threads. If the thread becomes blocked on a synchronization mechanism (such as a mutex lock) the state of the thread is saved in process memory. The threads library then assigns another thread to the LWP. See also bound thread, multithreading, thread.

For Solaris threads, a thread permanently assigned to a particular LWP is called a bound thread. Bound threads can be scheduled on a real-time basis in strict priority with respect to all other active threads in the system, not only within a process. An LWP is an entity that can be scheduled with the same default scheduling priority as any UNIX process.
Industry:Computer
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
A condition that occurs when one of the OPL system ASICs detects a parity error or equivalent fatal system error. Bus arbitration is frozen, so all bus activity stops.
Industry:Computer
A condition that occurs in cache when two unrelated data accessed independently by two threads reside in the same block. This block can end up 'ping-ponging' between caches for no valid reason. Recognizing such a case and rearranging the data structure to eliminate the false sharing greatly increases cache performance. See also cache, cache locality.
Industry:Computer
An XML file provided with each module and J2EE application that describes how they should be deployed. The deployment descriptor directs a deployment tool to deploy a module or application with specific container options and describes specific configuration requirements that a deployer must resolve.
Industry:Computer
An XML document that is syntactically correct. It does not have any angle brackets that are not part of tags, all tags have an ending tag or are themselves self-ending, and all tags are fully nested. Knowing that a document is well formed makes it possible to process it. However, a well-formed document may not be valid. To determine that, you need a validating parser and a DTD.
Industry:Computer
An XML document that controls the transformation of an XML document into another XML document or HTML. The target document often has presentation-related tags dictating how it will be rendered by a browser or other presentation mechanism. XSLT was formerly a part of XSL, which also included a tag language of style flow objects.
Industry:Computer
An organization or software vendor that provides tools used for the development, packaging, and deployment of J2EE applications.
