To qualify that statement, you'll have to build Julia from https://github.com/loladiro/julia rather than master, as there's still a few patches that are not yet merged into master.

cd is a shell intrinsic on Windows, not an actual program, so you can't actually call it. Also, we do have a julia function to achieve the same thing (and in more recent versions the <at> chdir macro), but I'm not sure if that's implemented in the version you have. As I said, the windows build is horribly outdated. Feel free to build Julia from source though.On Thu, May 17, 2012 at 10:45 PM, J Luis <jmfluis-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote:I didn't try parallel on Windows.

and leaves the processors running at 100% load till I kill the julia session.Note that in the above I had also Windows running under parallels, bur very sadly I'm not able to make this example run on Windows.Copy-paste of the function ends up all unformatted and complains about one '[' too much (or too less, forgot), and saving it into a file in julia's root dir doesn't load.julia> load("JGibbs")could not open file JGibbsin load at util.jl:199(actually all my very few attempts to run something on Windows ended up this way)Joaquim
