In computing, the producer-consumer problem (also known as the bounded-buffer problem) is a family of problems described by Edsger W. Dijkstra since 1965.. Dijkstra found the solution for the producer-consumer problem as he worked as a consultant for the Electrologica X1 and X8 computers: "The first use of producer-consumer was partly software, partly hardware: The component taking care of the ...
In some situations, overwriting circular buffer can be used, e.g. in multimedia. If the buffer is used as the bounded buffer in the producer–consumer problem then it is probably desired for the producer (e.g., an audio generator) to overwrite old data if the consumer (e.g., the sound card) is unable to momentarily
The Problem Reports and Solutions Control Panel applet was replaced by the Maintenance section of the Action Center on Windows 7 and Server 2008 R2.. A new app, Problem Steps Recorder (PSR.exe), is available on all builds of Windows 7 and enables the collection of the actions performed by a user while encountering a crash so that testers and developers can reproduce the situation for analysis ...
A classic concurrency problem is that of the bounded producer/consumer, in which there is a queue or ring buffer of tasks with a maximum size, with one or more threads being "producer" threads that add tasks to the queue, and one or more other threads being "consumer" threads that take tasks out of the queue. The queue is assumed to be non ...
WHEA "builds on the PCI Express Advanced Reporting to provide more detailed information about system errors and a common reporting structure." [ 4 ] WHEA allows third-party software to interact with the operating system and react to certain hardware events.
Further, (4) a common variant of the producer-consumer problem is to allow *multiple* producers and consumers, in which case an additional mutex is necessary in order to get mutual exclusion, but (5) the order in which producers / consumers wait and signal the mutex and semaphores may lead to deadlock if implemented incorrectly.
In computing, a process that is blocked is waiting for some event, such as a resource becoming available or the completion of an I/O operation. [1] Once the event occurs for which the process is waiting ("is blocked on"), the process is advanced from blocked state to an imminent one, such as runnable.
Version 4.0, part of Windows Vista and Windows Server 2008. New features include: [6] Subqueues, [7] improved support for "poison messages" (messages which continually fail to be processed correctly by the receiver), and support for transactional receives of messages from a remote queue. Version 5.0, part of Windows 7 and Windows Server 2008 R2.
