+# Parallel Operations for Kotlin
+Parallel *map*, *reduce*, and various indexed and in-place operations on collections for Kotlin using coroutines.
+
+The parallel *map* implementation is called *.mapParallel()*. It is implemented like this.
+```kotlin
+suspend fun <T, R> Iterable<T>.mapParallel(transform: (T) -> R): List<R> = coroutineScope {
+    map { async { transform(it) } }.map { it.await() }
+}
+```
+
+Example of using the parallel *map* operation.
+```kotlin
+fun showCase() {
+  val list = listOf(1,2,3)
+  runBlocking(Dispatchers.Default) {
+      var mappedList = list.mapParallel { it * 2 } // Results in [2,4,6]
+  }
+}
+```
+
+There is also the parallel *reduce* operation with chunked variations, which can be used to perform **associative** operations on a collection, like *sum*.
+
+**Note:** If you want to achieve multithreading, make sure to run the coroutine with the Default dispatcher.
+
+## Chunked operations
+Chunked operations improve performance since they split the collection into just a couple of segments,
+which are processed each by a single thread. That benefits from data locality and lesser thread management.
+It is particularly useful (pretty much needed for operations like sum) in the reduce operation when using multithreading,
+since each thread takes one chunk that it reduces on its own. After all coroutines finish, their results are then reduced again to the final result.
+
+## Gradle
+The library is published in the Maven Central repository.
+Include this line in your module build.gradle file.
+```gradle
+dependencies {
+    implementation("io.github.cvb941:kotlin-parallel-operations:2.0.0")
+}
+```
+
+## Future
+In the future, I would like other transformation functions to be implemented.
