River Trail was announced at the Intel Developer Forum in September 2011, and demonstrated using a Firefox extension developed by Intel. Brendan Eich, the original author of JavaScript, promised that he would promote River Trail within Ecma International, saying "The demo shows a 15x speedup over serial JavaScript. It lights up the ridiculously parallel hardware in modern CPUs and GPUs, for audio, video, image processing, automated voice response, computer vision, 3D gaming, etc. – all written in memory-safe, clean, functional JavaScript, without threads and their data races and deadlocks."[1] Because River Trail leverages Intel's OpenCL SDK[2] it can exploit multiple CPU cores as well as data parallel instructions (ex. AVX, SSE) and the speedup can be greater than the CPU core count would imply. A native implementation of River Trail in Firefox's SpiderMonkey JavaScript engine was announced in September 2012[3] and was added to nightly Firefox builds in April 2013.[4] By January 2015, the code had been removed from Firefox.[5][6] OperationTo use the engine scripts uses a special API, based on three pillars: a type called References1. ^{{cite web | title = Intel extends JavaScript for parallel programming | author = Cade Metz | date = 17 September 2011 | url = https://www.theregister.co.uk/2011/09/17/intel_parallel_javascript/ | publisher = The Register | accessdate = 2013-04-10 }} 2. ^{{cite web|last=Hillar|first=Gaston|title=Introducing Intel Labs' River Trail|url=http://www.drdobbs.com/web-development/introducing-intel-labs-river-trail/231602396|work=Dr. Dobb's|date=29 September 2011|accessdate=29 January 2014}} 3. ^{{cite web | title = Intel boosts JavaScript with River Trail release | author = Gareth Halfacree | url = http://www.bit-tech.net/news/bits/2012/09/13/intel-river-trail/1 | date = 13 September 2012 | publisher = bit-tech | accessdate = 2013-04-10 }} 4. ^{{cite web | url = https://bugzilla.mozilla.org/show_bug.cgi?id=829602 | title = Bug 829602 - ParallelDo intrinsic and self-hosted ParallelArray | publisher = Mozilla Foundation | accessdate = 2013-04-10 }} 5. ^{{Cite web|url = https://bugzilla.mozilla.org/show_bug.cgi?id=801869|title = Bug 801869 - (PJS) PJS: Efficient threaded runtime for data-parallel JavaScript|date = 2015-01-19|accessdate = 2015-04-23|website = Bugzilla@Mozilla|publisher = Mozilla Foundation|last = |first = }} 6. ^{{Cite web|url=https://groups.google.com/forum/m/#!topic/mozilla.dev.tech.js-engine/H-YEsejE6DA|title=PJS has been removed from Spidermonkey|accessdate=2017-10-18}} 7. ^{{Citation|title=Three pillars of the API|url=https://github.com/RiverTrail/RiverTrail/wiki/Three-Pillars-of-the-API|accessdate=2011-09-14}} External links
