[julia-users] Re: Factorization of big integers is taking too long
Tim is correct in a sense. I translated some big int code a while ago, I
think it was the pollard rho method (don't quite remember the details) and
the inability to reuse storage for a bigint caused a big performance hit.
(I thought about some workaround, but unfortunately I don't remember what
it was or if I even tried it)
Stefan wrote a simple stop-gap factor() routine and noted in a comment that
it needs to be improved. But Bill Hart is correct: It can't do 3^100 + 2 no
matter how efficient bigint arithmetic is.
The Maxima routines and the perl module by Dana Jacobsen are good, but they
would require translating and asking the authors to liberalize the license.
I wrapped the msieve c library.
https://github.com/jlapeyre/PrimeSieve.jl
It does 3^100 + 2 in less than a second on my machine

It is calling GMP, but the GMP software cannot be the reason as this works

Is this a bug? Did I do something wrong?
The first factor, 31721, is not even large. Mathematical software such as
GAP or PARI/GP will factorize this in much less than a second.

Re: [julia-users] Re: inserting an Expr into AST via macro
Thank you Jameson, that makes a lot of sense. Generally I try to organize my code to build up a single Expr, but sometimes it makes for less than ideal code. Out of curiosity, would it make sense for Julia to have an 'insert' function to convert Expr's to ASTs? This would help alleviate the need for macros in certain cases as well 'eval'. For example, in my case, if I had: fn_expr = parse_action_definition(rule) # fn(rule, first, last, children) rule.action = insert_expr(fn_expr) would cause `rule.action` be set to the actual function, rather than the Expr. If you tried to use `eval`, not only is it frowned on, but it would also fail because of it's global scope. While ultimately you can by, as you suggest, with building up the Exprs, I think something like this would allow for easier to read/maintain code. On Thursday, March 19, 2015 at 12:43:29 AM UTC-4, Jameson wrote: writing a code snippet like val = :(parsefloat(3.1459)) @test2(val) is perhaps a great way to confuse yourself, although it is a common mistake. the problem is that it makes it seem like the two arguments execute in sequence, whereas the macro expansion pass actually runs prior to the code execution. it should, therefore, be viewed in complete isolation from the runtime expressions. in pseudo-code, that might look something like: fullexpression = macroexpand(:(@test2(val))) /// val = :(parsefloat(3.1459)) $fullexpression in summary, macros are functions whose arguments are syntax, not values. when a macro is executed, val does not get passed as reference to a value stored in a variable, it is the expression tree that describes that variable. that is the fundamental distinction between a function and a macro. but, it doesn't sound like you need a macro. macros that call other macros can get really confusing really quickly. but a normal function will perhaps do exactly what you wanted anyways? it's perfectly valid for you to write a function that takes `val` in as an argument and returns some new expression (which you can then combine with other expressions before returning the whole thing from the main macro) On Wed, Mar 18, 2015 at 9:51 AM Abe Schneider abe.schnei...@gmail.com http://mailto:abe.schnei...@gmail.com wrote: Unfortunately my solution only works if you pass in an expression directly. If you try something like this: val = :(parsefloat(3.1459)) @test2(val) It will fail, since `val` is a symbol. Any other ideas? The reason I'm trying to solve the problem in the first place is that I have semantic actions attached to rules formed in a grammar. The actions take the form of expression, which I want to wrap up in a function like: (rule,first, last,children) - $ex where `$ex` is my found expression. If I do this in my main macro, everything work correctly. However, the logic gets more complicated, because I want to allow semantic actions to be tied to any subrule, which means it has to be handled in the definition parsing functions. That should be fine, but I try to create a function that wraps my function, I get into this issue. I can't just insert the expression into the AST like I did before.in the main macro.

Re: [julia-users] Some simple use cases for multi-threading
Hey Stefan, Depending on how well Julia-generated code performs, some important concurrent data structures might be better implemented in C and wrapped. I would argue that until we can implement efficient concurrent data structures in pure Julia, the work isn't complete. It's ok to use C code as an interim solution while we're developing this, but in the longer term, we should not be forced to rely on C to write libraries. Think of the implementations in C as though we're dropping into inline assembly for maximizing performance. In actual fact, using alignment directives, padding, SIMD intrinsics, or specialized load/store instructions _is_ pretty much assembly. I don't see value in adding this sort of architecture-specific explicit control to Julia--it negates the high-level, high-productivity aspect if you have to throw in pragmas like assume_aligned in your code for performance reasons. And if you go down that road, then you're competing with C.

`ccall(jl_, Void, (Ptr{Uint8},), Line 305)` will probably work. (beware
that YMMV as this is a debugging function that does not support all data

[julia-users] Running external programms in windows, quotes vs. double quotes
Hello, I currently try to make the LaTeX.jl package from rened windows friendly. However I run into problems because of julias command interplation. I try to open a pdf file in some pdf viewer. In windows you can do that with following command start SOME_DOCUMENT.pdf However spawn(`start $pdfname`) will result in start '' 'SOME_DOCUMENT.pdf' Double quotes have been replaced by single quotes and the string was also encapsulated by quotes (looks like because of the presence of backslashes). So my questions are: 1) Is there a workaround or some way to manipulate how quotes are handles. Guess some way to execute a raw command line would be enough. 2) Is this a bug in Julia. Thanks! Florian
Re: [julia-users] Re: Some simple use cases for multi-threading
I have to vote in this direction too. One thing I did very successfully in C++11 was to make a window running in a separate thread that I could feed lamda functions to. The lambda functions would run openGL commands to visualize data that the functions closed over. This turned out to be a hugely helpful, but I haven't found a good way to do it properly in Julia.

[julia-users] Re: Error or supposed to happen? compile
Since string.jl is part of the bootstrap, there are things that won't be available yet when that part of the image is built. It looks like in this case STDOUT, which is the default target for println, hasn't been defined yet. What are you trying to do with this print? There may be another solution.

Re: [julia-users] Re: Error or supposed to happen? compile
I did try your suggestion (`ccall(jl_, Void, (Ptr{Uint8},), Line 305)`
will probably work.) but got an other Error
libc.jl
libdl.jl
env.jl
error during bootstrap:
LoadError(at sysimg.jl line 106: LoadError(at env.jl line 110:
UndefVarError(var=:Uint8)))
Thanks anyway - was just a try..

Which is failing on line 3 (in the creation of the graph).
What's the proper way of creating the object from a parameterized type?

Re: [julia-users] Re: Error or supposed to happen? compile
The argument to the jl_ function is of type Any not Ptr{Void}
It also now bails at a depth of 25 by printing •, so it should fail as
badly anymore on recursive types

Re: [julia-users] Running external programms in windows, quotes vs. double quotes
1) Is there a workaround or some way to manipulate how quotes are handles. Guess some way to execute a raw command line would be enough. Here is some example code you could use to create processes directly on Windows: https://gist.github.com/ihnorton/82dc5b41a537de710ab2 2) Is this a bug in Julia. Known issue, more or less. We are somewhat fighting against libuv's attempts to be extra-helpful here. I'm not sure what is the best way to improve this.

Re: [julia-users] Running external programms in windows, quotes vs. double quotes
This works nicely. However I had to change the command to command = cmd /K start \\ $pdfname start seems to need the cmd.exe shell to work. Thank you very much.
