While `brew install xz` had trouble, I found my /usr/local/include and

FWIW, I have seen a 25% regression from 0.3 to 0.4 on a reasonably complex
codebase, but haven't been able to isolate the offending code. GC time in
the 0.4 run is significantly smaller than 0.3, which means that if you
discount GC, the difference is more like 40%. I wonder if this is some

Unless you really need to use some MPI functionality, why not use the
built-in parallel processing capabilities? Does using MPI give a major
performance benefit in your case?

FWIW, the julia sparse matrix vector multiplication is very simple. I
expect that further speedups possible by using libraries such as OSKI or
MKL. In the ideal world, we would have autotuning kernels in Julia itself.

Hello,
How do I initialize this composite type in Julia?
type foo
a::Int64
function boss()
println("Hey, boss!")
end
end
If I do f = foo(1), then I get the following error:
ERROR: MethodError: `convert` has no method matching convert(::Type{foo},
::Int64)
This may have arisen from a
git bisect?
Perhaps the leading candidate is

Julia is not object oriented, so you only put constructors inside the type
definition, which are then inner constructors.
Inner constructors overwrite the default constructor, so the function
boss() replaces foo(::Int64).
What you probably want is:

function boss(::foo)

@Simon that was my original thought, too. But, this actually works for me:

My reason for using MPI is simply that I'm used to MPI, and t is very easy
for me to adapt existing Octave code that uses MPI to use Julia instead of
Octave. For code such as these Monte Carlo examples, I doubt that it would
make much difference if one were to use pmap, for example, instead of M
Thanks for the explanation. That does seem reasonable. We do go through a few
hoops to make MPI work with Julia, but so long as it works fine for you - that
is indeed great news!

Thank you for your suggestions.
I haven't tried Cxx.jl, since that apparently requires some effort
installing a new LLVM, which makes it harder to convince others to use the
bindings.
Your second suggestion is unfortunately going in the wrong direction,
taking a Julia array and passing it to C.

You can build an binary executable with this script:

compiles the scripts main function into Julia's sysimg. I have used it myself
to distribute a small program.
I understand and concur with your comment regarding the proper use of
abstract types. And yes, defining appropriate abstractions is challenging.
A few more iterations will likely be required for us. For now, most of my
hesitations concern how to extend a given object and its functionality: say

Yes, thanks anyway. I sent a trimmed down version to John Myles White.
Seems the file might contain non-valid UTF-8 but then it should not be
possible to read it in via readtable imho since writetable will then fail.
Might be something else though.

Out of interest, does your code use arrays (for positions if the particles

Hi all,
In v0.3.x, I can't seem to do the following (I get a "no method exists"
error):
randn(10)[IntSet(2, 3, 4)]
Is this possible in v0.4? If not, is there a reason why I shouldn't want
the ability to do this?
Cheers,
Colin
No, this isn't implemented in 0.4, either. It is something I've thought about,
but IntSet's current semantics aren't quite right for the job. See:
https://github.com/JuliaLang/julia/pull/10065#issuecomment-93853097
It may be worth splitting that PR out into the IndexSet package for this
purpose
But Simon, Julia allows me to define this composite type. There just
doesn't seem to be any obvious way to create an object of that type.
Additionally, writing the type that way results in the same error.

You shouldn't need root access. Just did this few weeks ago (downloaded and
