ParallelArray Redirect 1

This content covers features introduced in Firefox 17

Obsolete since Gecko 29 (Firefox 29 / Thunderbird 29 / SeaMonkey 2.26)
This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.

Non-standard
This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

Note: As of Gecko 22, this object is disabled in the Beta, Release and ESR channels (bug 853067). This object has been removed from Gecko 29 in favor of ParallelJS (PJS) currently available in the Nightly channel (bug 944074).

Summary

The goal of ParallelArray is to enable data-parallelism in web applications. The higher-order functions available on ParallelArray attempt to execute in parallel, though they may fall back to sequential execution if necessary. To ensure that your code executes in parallel, it is suggested that the functions should be limited to the parallelizable subset of JS that Firefox supports.

Syntax

new ParallelArray()
new ParallelArray([element0, element1, ...])
new ParallelArray(arrayLength, elementalFunction)

ParallelArray instances

Properties

length
Reflects the number of elements in the ParallelArray.

Methods

map
Apply map callback to array elements.
reduce
 
scan
scatter
Scatter array elements.
filter
flatten
partition
get
Get ParallelArray element.

Examples

Example: Using map in parallel

var p = new ParallelArray([0, 1, 2, 3, 4]);
var m = p.map(function (v) {
  return v + 1;
});
