This is great, thanks!
I verified pointer(X) is the same as what pointer(x_next) used to be before
running your line of code, and pointer(x_next) after running your line of
code is the same as pointer(x).
I did not know of this about Julia!

Hi,
Are you sure that you need a copy operation? If I understand correctly what you
are doing, you just need access to the x from the previous iteration.
Could you not just swap x and x_next and avoid the copy :
X, x_next = x_next, x
(so you create them once only).
Is there a version of copy!() that uses @parallel? My x and x_next are
usually huge.

Hey John,
Ah geez, copy!() was only 2 lines lower than copy() in abstractarray.jl.
Thanks!

oops, add
@assert eltype(a) == eltype(b)
in the checks too, otherwise there might be an "inexact error" when mixing
integers and floats.
Why not use copy!

This kind of routine is what I'm talking about...
# copy assignment for vectors
function copyassignment!(a::Vector,b::Vector)
@assert length(a) == length(b)
for n=1:length(a)
a[n]=b[n];
end
end
My questions:
1) Is there a standard function that does this?
2) Is there a better
