Queue processor

In the ccdc-queue section in the lower show command area, the list of currently queued, running, and completed jobs are shown. Momec3 uses multiple processors, if available on your computer, to run more than one calculation at a time. In the... 

In [67], Ha extends this work to consider multiple customer classes that differ in their demand, delay costs, and service costs. For an M/G/s processor sharing queue, he shows that a single fee dependent on the time in the system can coordinate the system, and for an M/G/1 FIFO server, coordination can be effected through a pricing scheme that is quadratic in time of service. 

FIFO ordering for global requests can easily be implemented as an ordered list, either dynamic or static. It is worth noting that MrsP can do with simple fixed-length lists because the maximum length of the FIFO queue is known a-priori, independently from the specific application, as the number of processors available determines the maximum degree of parallelism for the platform. The use of a dynamic list is also a viable option since each task can participate at most in one FIFO queue, it is possible to statically allocate a node for each task, and then add or remove it from a specific resource list when required. 

Resource lock manages the ceiling and the FIFO queue in 800 ns, when it is necessary to yield the processor to the resource holder it updates the remote partition and perform the migration in 8,000 ns, and each spinning cycle costs 500 ns (maximum delay to stop spinning). 

The co-processor contains two independent 16-byte wide receive and transmit FIFO queues. Direct memory access (DMA) is supported to off-load the processor during reception and transmission. To receive data frames from the Ethernet line, the host CPU reserves a buffer space in main memory and invokes the co-processor. The asynchronously arriving data frames are received by the co-processor and stored into a local memory. A DMA receiver module then writes the data frames to main memory. To transmit data on the Ethernet line, the host CPU invokes the co-processor with a pointer to the location in main memory containing the data. The co-processor consmicts a data frame by reading the data fields from main memory and then transmits it over the Ethernet... 

Processor 1 activates the run command. At this time the AGENDA is empty and the match queue has an entry. The run command waits for a ruie to enter the AGENDA. At the same time, Processor 2 performs the matching operation for initiai-fact and loads the rule into the AGENDA.
