static int ParallelTaskImageProcessing(Bitmap source1, Bitmap source2, Bitmap layer1, Bitmap layer2, Graphics blender) { Task toGray = Task.Factory.StartNew(() => SetToGray(source1, layer1)); Task rotate = Task.Factory.StartNew(() => Rotate(source2, layer2)); Task.WaitAll(toGray...
seven of them will run the PLINQ query while the remaining processor runs the foreach loop on the output of the PLINQ query as elements become available. This carries the benefit of allowing more incremental processing of output, thus reducing the memory requirements necessary to hold the results...
but there is only one datafile in the tablespace, then internal fragmentation may occur, as shown inFigure 21-5. The pockets of free space within the internal table extents of a datafile cannot be coalesced with other free space and cannot be allocated as extents. ...
If the body of the loop performs only a small amount of work, you may find that you achieve better performance by partitioning the iterations into larger units of work. The reason for this is that there are two types of overhead that are introduced when processing a loop: the cost of ...

Data-parallel processing maps data elements to parallel processing threads. Many applications that process large data sets can use a data-parallel programming model to speed up the computations. In 3D rendering large sets of pixels and vertices are mapped to parallel threads. Similarly, image and ...
(In an Oracle Parallel Server, however, the parallel server processes may be spread across multiple instances.) Parallel server processes are also sometimes called "slave processes". When an operation is divided into pieces for parallel execution in a massively parallel processing (MPP) configuration...
Processing Query OutputAs already noted, due to deferred evaluation, parallelism doesn't get introduced until you start processing the output of the query. If you're familiar with IEnumerable<T>, this equates to calling the GetEnumerator method. There are three basic ways that PLI...
If you set this parameter too low, some queries may not have a parallel execution process available to them during query processing. If you set it too high, memory resource shortages may occur during peak periods, which can degrade performance. ...
