Hi
I wrote the following benchmark and I got some weird results which I am
unsure of their correctness.
a=fill(1.0,10000000);
b=fill(0.0,10000000);
f()=@elapsed @parallel for i=1:10000000
b[i]=a[i]
end
I get the following results-
julia> f()
0.001288817
julia> f()
4.0828e-5
julia> f()
4.3807e-5
julia> f()
4.2003e-5
The first result is probably due to function f() being compiled and after
that, there is couple of orders of magnitude gain in performance. Is this
benchmark correct or there is some problem with the code ?
The corresponding C code takes on average 0.029588 seconds. Is Julia that
much faster than C ?
