The timing for the Fortran code (using -Ofast) is
outer_func2 time = 0.160010 second.
I checked and it is using vector instructions. I'm impressed Julia is as
fast as Fortran in this case. I would have thought alias checking would
Julia down.
The Julia code is slow on release-0.5 as well a
I noticed this morning that the loop are in the wrong order for a column
major array. Reversing them, I get:
testing outer_func
0.294904 seconds
0.296689 seconds
testing outer_func2
0.280391 seconds
0.281223 seconds
Now both versions have the phi instructions, so I guess that wasn't the
Could it be some alias checking going on?
Anyway, this code is horribly slow on 0.6 (even with #19097) it seems.
to_indexes(::Int64, ::Int64, ::Vararg{Int64,N}) at operators.jl:868
(repeats 3 times)
kills performance.
