摘要： A system is set forth that includes a processor, one or more memory storage units, and software code stored in the one or more memory storage units. The software code is executable by the processor to generate a plurality of adaptive partitions that are each associated with one or more process threads. Each of the plurality of adaptive partitions has a corresponding processor budget that is assigned to it. The process threads include a mutex holding thread and a mutex waiting thread. The mutex holding thread is associated with a first adaptive partition and may gain exclusive access to a mutex object. The mutex waiting thread is associated with a second adaptive partition and must wait for access to the mutex object while the mutex object is held by the mutex holding thread. The software code further includes a scheduling system that selectively allocates the processor to run the process threads based, at least in part, on the processor budget of the associated adaptive partitions. The scheduling system bills processor allocation used to run the mutex holding thread to the processor budget of the second adaptive partition when the processor budget of the first adaptive partition has been exhausted.

摘要： A system is set forth that includes a processor, one or more memory storage units, and software code stored in the one or more memory storage units. The software code is executable by the processor to generate a plurality of adaptive partitions that are each associated with one or more process threads. Each of the plurality, of adaptive partitions has one or more corresponding scheduling attributes that are assigned to it. The software code further includes a scheduling system that is executable by the processor for selectively allocating the processor to run the process threads based on a comparison between ordering function values for each adaptive partition. The ordering function value for each adaptive partition is calculated using one or more of the scheduling attributes of the corresponding adaptive partition. The scheduling attributes that may be used to calculate the ordering function value include, for example, 1) the process budget, such as a guaranteed time budget, of the adaptive partition, 2) the critical budget, if any, of the adaptive partition, 3) the rate at which the process threads of an adaptive partition consume processor time, or the like. For each adaptive partition that is associated with a critical thread, a critical ordering function value also may be calculated. The scheduling system may compare the ordering function value with the critical ordering function value of the adaptive partition to determine the proper manner of billing the adaptive partition for the processor allocation used to run its associated critical threads. Methods of implementing various aspects of such a system are also set forth.

The software code is executable by the processor to generate a plurality of adaptive partitions that are each associated with one or more process threads. Each of the plurality of adaptive partitions has a corresponding processor time budget. One or more of the process threads are designated as critical threads. Each adaptive partition associated with a critical thread is assigned a corresponding critical time budget. The software code also includes a scheduling system that is executable by the processor for selectively allocating the processor to run the process threads based, at least in part, on the processor time budgets of the respective adaptive partitions. The scheduling system may allocate the processor to run a critical thread based on the available critical time budget of the associated adaptive partition even when the processor time budget of the associated adaptive partition has been exhausted. In one example, the scheduling system functions SO that it only bills the critical time budget of an adaptive partition for time used to run an associated critical thread when the processor is overloaded and the critical time budget for the adaptive partition is concurrently exhausted. Methods of implementing such a system are also set forth.

摘要： A system is set forth comprising a processor and memory storage units storing software code. The software code comprises code for a scheduling system and for generating a plurality of adaptive partitions that are each associated with one or more software threads and that each have a corresponding processor budget. The code also is executable to generate at least one sending thread and at least one receiving thread which responds to communications from the sending thread to execute one or more tasks corresponding to the communications. In operation, the scheduling system selectively allocates the processor to each sending and receiving thread based on the processor budget of the adaptive partition associated with the respective thread. The scheduling system bills the processor budget of the adaptive partition associated with the sending thread for processor allocation used by the receiving thread to respond to communications sent by the sending thread.

摘要： An adaptive partition scheduler is a priority-based scheduler that also provides execution time guarantees (fair-share). Execution time guarantees apply to threads or groups of threads when the system is overloaded. When the system is not overloaded, threads are scheduled based strictly on priority, maintaining strict real-time behavior. Even when overloaded, the scheduler provides real-time guarantees to a set of critical threads, as specified by the system architect.
