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 As I said, the windows build is horribly outdated.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.

I didn't try parallel on Windows. What do I have to do to load a file?

I'm not even able to change directory

julia> run(`cd ..`)

CreateProcessW: The system cannot find the file specified.

Parallel processing is not implemented yet on windows and the public build for windows is outdated, which is probably why you experienced trouble (I'll publish a new build in two weeks or so, when I finally have some more time to devote to this).

Hi,

On OSX MacBook Pro i7 2.66 GHz 

With one processor only

julia> sum([ <at> elapsed dJGibbs3a(20000, 200) for i=1:10])

4.398758888244629

with julia -p 4 it runs the first time

julia> sum([ <at> elapsed dJGibbs3a(20000, 200) for i=1:10])

2.1773054599761963

but 'disconnects' on the second run

sum([ <at> elapsed dJGibbs3a(20000, 200) for i=1:10])DisconnectException()DisconnectException()DisconnectException()

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 JGibbs

 in load at util.jl:199

(actually all my very few attempts to run something on Windows ended up this way)

Could you build Julia in debug mode and post a backtrace?
