Examples of BlockedRange

com.impetus.labs.korus.addons.constructs.parallelfor.BlockedRange
BlockedRange is a single unit of block that can be executed in a single iteration. Suppose, we have an iteration space from 0 to n. Then, an object of blocked range will be constructed whose first argument will be the start of the iteration and second argument will be end of the iteration. A third argument grainSize will also have to be specified which breaks these BlockedRanges into units which can be executed by a single core or processor.

BlockedRange range= new BlockedRange(1,10000,1250);

will finally construct 10000/1250 = 8 BlockedRanges

Examples of com.impetus.labs.korus.addons.constructs.parallelfor.BlockedRange

    // Specify begin, end and grainSize according to the machine
    int begin = 1;
    int end = number;
    int grainSize = 20000;


    BlockedRange range = new BlockedRange(begin, end, grainSize);


    // Create an object of a class extending ParallelTask Class
    ParallelFactorial af = new ParallelFactorial(parallel, range);


    // Pass the object to the parallelFor construct
