Right, you need some way to ensure that the functions applied to the array
are "pure", the array doesn't mutate, etc. I thought perhaps your
ParallelArray() type would be ensuring this (e.g., by enforcing type
checking and freezing the array), but maybe I misunderstood you? Even then,
I'm not sure
I'm not sure what you mean here: a parallel array is simply an array of
numbers; there is nothing "magic" about it.
If we _really_ wanted to be blunt about it, we could simply say (in Array.map)
if (length >= giant && function.isEasyPeasy() && everything in the array is a
number)
return doHa
Right, I get how ParallelArrays would work. I was asking Filip how you
might infer that an array could be a ParallelArray.

The parallel arrays apis aren't a magic "make my code parallel" wand.
They don't make general code parallel, they simply provide a bunch of functions
like map, etc where if you restrict your list of language features to a
specific subset, they'll vectorise it.
For instance
ParallelArray([1,2,3

Hi Oneal.
As pointed out by Jesus, Samsung is working on a WebCL implementation for
WebKit. https://github.com/SRA-SiliconValley/webkit-webcl is being our
staging repo.
As for your question, it is a bit unclear that if by "multi-process
support" you are referring the Web/UI process model provided
Hi.
Correct WebCL link is https://github.com/SRA-SiliconValley/webkit-webcl .

Hi,
WebKit already support a split process model which is what we call WebKit2 [1].
I'm not aware of any official plans of supporting WebCL but I believe
Samsung was doing some research on this [2].

Hello, I'm a researcher and I just focusing on the multi-process supporting and
WebCL supporting in browser engin. so I have some concerns about the both
features.
In recently, Google has pronounced that they will support the multi-process in
their browser egin(Blink) which is forked from the w
