It then discusses in depth how to use divide-and-conquer recursive parallelism to perform a basic reduction—namely, summing the elements of an array. It then generalizes this discussion to other reductions as well as map operations and parallel operations over other data structures. It then ...
There are a few ways to speed-up sorting with p/sort:Vector inputs are preferable than sequences. Shave additional milliseconds by using the raw array output, by enclosing p/sort in a binding like (binding [p/*mutable* true] (p/sort coll)). p/sort returns an object array in this ...
To execute a query in parallel, Oracle generally creates a producer queue server and a consumer server. The producer queue server retrieves rows from tables and the consumer server performs operations such as join, sort, DML, and DDL on these rows. Each server in the producer execution process...
As for the DBMS itself, the following are some of the features inherent of the DBMS itself: Parallel compression/decompression Parallel format buffer translation Parallel sorting, retrieval, and searching Command/Protection Logging Universal Encoding Support Online Utilities For more information about Ada...
FIGURE 3. Array processor. A processor array consists of a number of processing elements (PEs) linked by a network with regular topology. Each processing element has its own memory to store local data. As in a conventional machine, it is important that an array processor implementation supports...

multi-threadingA central problem in software engineering applied to large databases is External Sorting. Here we discuss an algorithm implemented with Java, using it's multi-threading capability. It is shown that the parallel version is about ten percent faster.Marcelo A. Bittencourt...
In (3), we show that preliminary infrastructure tuning results in sorting 1TB data in 14 minutes on 10 Power 730 machines running IBM InfoSphere BigInsights. Further improvement is expected, among other factors, on the new IBM PowerLinuxTM 7R2 systems. By: Anne E. Gattiker, Fadi H. ...
