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 synchronise 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
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 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. recognising such a case and rearranging the data structure to eliminate the false sharing greatly increases cache performance. See also cache, cache locality.

Extensible Stylesheet Language. A standard that lets you do the following:
*Specify an addressing mechanism, so that you can identify the parts of an XML document that a transformation applies to (XPath).
*Specify tag conversions, so that you can convert XML data into different formats (XSLT).
*Specify display characteristics, such page sizes, margins, and font heights and widths, as well as the flow objects on each page. Information fills in one area of a page and then automatically flows to the next object when that area fills up. That allows you to wrap text around pictures, for example, or to continue a newsletter article on a different page (XSL-FO).
Industry:Computer
A concatenation of XSLT transformations in which the output of one transformation becomes the input of the next.
Industry:Computer
A computer programme that enables the automation of a well defined activity by performing a specific well defined task when it detects a predetermined set of conditions.

Electronic Business XML. A group of specifications designed to enable enterprises to conduct business through the exchange of XML-based messages. It is sponsored by OASIS and the United Nations Centre for the Facilitation of Procedures and practises in Administration, Commerce and Transport (U.N./CEFACT).
