Contents
Motivation
There are many incantations of the fork_loop. We gain experience with selecting the right one for two scenarios.
Background
Code To Use
FJ<E>
class FJ<E>
Code To Implement
Echoes
class: | Echoes.java | |
methods: | toEchoes | |
package: | forkloop.group | |
source folder: | student/src/main/java |
toEchoes
method: public static List<String> toEchoes(List<String> texts)
(parallel implementation required)
for each text in parallel, produce text + " " + text
.
toEchoes
accepts a List<String> parameter and returns a List<String>.
List<E> is an Iterable<E>, so instances of List<E> can be passed to join_fork_loop(iterable, task).
client
class: | EchoClient.java | DEMO: |
methods: | main | |
package: | forkloop.client | |
source folder: | src/main/java |
SquareRoots
class: | SquareRoots.java | |
methods: | toSquareRoots | |
package: | forkloop.group | |
source folder: | student/src/main/java |
toSquareRoots
method: public static Double[] toSquareRoots(Double[] values)
(parallel implementation required)
client
class: | SquareRootClient.java | DEMO: |
methods: | main | |
package: | forkloop.client | |
source folder: | src/main/java |
Testing
class: | _ForkLoopTestSuite.java | |
package: | forkloop.group | |
source folder: | testing/src/test/java |
