Hello everyone,
I am working on a Julia code which is a brutal copy of a Matlab code and
found out that the Julia code is slower.....
So I did some naive benchmark and found strange results...
I did look for solution on The Internets but... I found nothing usefull
that why I'm asking the question here.
Maybe someone have an idea of why the Julia code is slower than MATLAB?
(because the official benchmark say that it should be quicker )
PS: I know that it's a bit of a recurrent question....
The codes are
Julia code
nbp = 2^12;
m = rand(nbp,nbp);
a = 0.0;
Mr = zeros(nbp,nbp);
tic()
for k = 1:nbp
for kk = 1:nbp
Mr[k,kk] = m[k,kk]*m[k,kk];
end
end
toc()
Elapsed time: 7.481011275 seconds
MATLAB code
nbp = 2^12;
m = rand(nbp,nbp);
a = 0.0;
Mr = zeros(nbp,nbp);
tic
for k = 1:nbp
for kk = 1:nbp
Mr(k,kk) =m(k,kk)*m(k,kk);
end
end
toc
Elapsed time is 0.618451 seconds.
