Motivation
X10/Habanero like Phasers have been added to Java since JDK7. We will gain some experience with using Phasers in a parallel for loop context.
Background
Mistakes To Avoid
 Warning: Phasers are brittle. |
Code to Implement
| class: | ForForallIterativeAverager.java |  |
| methods: | iterativelyAverage | |
| package: | iterativeaveraging.studio | |
| source folder: | student/src/main/java |
method: public void iterativelyAverage(List<Slice<double[]>> slices, double[] a, double[] b, int iterationCount) 
(parallel implementation required)
| class: | ForallForPhasedIterativeAverager.java | |
| methods: | iterativelyAverage | |
| package: | iterativeaveraging.studio | |
| source folder: | student/src/main/java |
method: public void iterativelyAverage(List<Slice<double[]>> slices, double[] a, double[] b, int iterationCount) (parallel implementation required)
Testing Your Solution
Correctness
| class: | IterativeAveragingTestSuite.java |  |
| package: | iterativeaveraging.studio | |
| source folder: | testing/src/test/java |
Performance
| class: | IterativeAveragingTiming.java |  |
| package: | iterativeaveraging.studio | |
| source folder: | src/main/java |
