pmap performance degradation after 30-40 min of work?

[Jim foo.bar]

Hi all,

I finally found an ideal use-case for pmap, however something very 
strange seems to be happening after roughly 30 minutes of execution!


Ok so here is the scenario:

I've got 383 raw scienific papers (.txt) in directory that i'm grouping 
using 'file-seq' and so I want to pmap a fn on each element of that seq 
(each document). The fn takes a document and a dictionary and annotates 
the document with terms found in the dictionary. Basically it uses regex 
to tag any occurrences of words that exist in the dictionary. When 
pmapping is finished, I should have a list of (annotated) strings that 
will be processed serially (doseq) in order to produce a massive file 
with all these strings separated by a new-line character (this is how 
most adaptive feature generators expect the data to be).


So you can see, this is perfect for pmap and indeed it seems to be doing 
extremely well but only for the first 240 papers roughly! all the cpus 
are working hard but after approximately 30-40 min  cpu utilisation and 
overall performance seems to degrade quite a bit...For some strange 
reason, 2 of my cores seem to refuse to do any work after these 240 
papers which results in a really really slow process. When I start the 
process it is going so fast that I cannot even read the output but as I 
said after 30-40 min it is getting unbelievably slow! Had the 
performance been stable I reckon I  need less than 60 min in order to 
annotate all 383 papers but with the current behaviour I have no choice 
but to abort and restart it passing it the leftovers...


any ideas? are there any issues involved with creating that many futures?

Jim

Have you tried running jconsole to monitor the memory usage?  It sounds
like maybe you're running out of heap space and you're mainly seeing the
garbage collector doing it's thing vs your actual program.

Re: pmap performance degradation after 30-40 min of work?

[Jim foo.bar]

No i haven't profiled memory , only cpu but what you're saying makes 
perfect sense. In every single iteration (each file) I'm 'slurp'-ing the 
2 files (the dictionary and the file to annotate)  provided. Would you 
suggest a different GC if that is the case or simply stop slurping?

Re: pmap performance degradation after 30-40 min of work?

[Adam]

If you have the memory you could just increase the heap size to a higher
value (like -Xmx2048m or something).  But even if you do that I would still
run jconsole to see what's happening.

Re: Interest in Scribble for Clojure?

[Gary Johnson]

I see. After taking a closer look, I can see that you could do LP in 
Scribble as well as also outputting some different kinds of documentation 
formats, such as Javadocs or standalone documents. The downside I'm seeing 
is that this all has to be programmed in Scheme and that you may have to do 
some IMO less than attractive backquoting to get at the underlying LaTeX if 
you want PDF outputs which use some of the existing LaTeX packages (math 
libs come to mind).

I suggested Org-mode on this thread for these reasons:

1. Many Clojure users are also Emacs users.
2. Org-mode is built into Emacs and requires no additional install.
3. Org-mode is not tied to any one language and already has a module for 
Clojure LP development.
4. It can output to ASCII, HTML, LaTeX, PDF, DocBook, OpenDocument Text, 
TaskJuggler, Freemind, and XOXO formats.
5. Tangling and in-file live evaluation are very neat features.
6. It can produce both standalone reports and websites depending on the 
chosen export module.
7. Inline LaTeX is directly supported without any special backquoting and 
exports correctly to both HTML and PDF outputs.

Scribble definitely looks like a powerful language for programmatically 
generating documentation, and if someone wants to take on a Clojure port, I 
can see why that might be a very compelling idea. I just wanted to drop a 
pointer to a somewhat lower hanging fruit.

Sorry to hijack your thread.

Rouge: Ruby + Clojure

[Arlen Christian Mart Cuss]

Hi all,

I'd like to announce Rouge, which is an implementation of Clojure on Ruby.

https://github.com/unnali/rouge#readme

The readme above shows example of some Rouge code, most of which is 
currently taken from the boot file of Rouge itself.  The thing is fully 
TDDed, so you can read the specs to see how (in)complete it is. :)

I'd love it if you gave it a try, and let me know your thoughts and 
feedback.  Even more than that, I'd love your contributions!  Clojure is a 
beautiful language, and I'm really happy to be able to combine it with my 
other favourite language.

Cheers,

Arlen

Re: Issues with Penumbra

[AtKaaZ]

Upon further inspection(s) I notice that the penumbra-0.6.0.jar does not
contain the java .class files for
at least PenumbraSystem but also the Natives
which is a bit odd because when doing lein uberjar  they do get compiled
and included (70Kb vs 60 kb .jar)
So I believe this is why the error:
ClassNotFoundException penumbra.PenumbraSystem
java.net.URLClassLoader$1.run (:-1)

I'm not sure, but that second one looks pretty fine to me.  It's also a lot 
more obvious where the function comes from.

Re: Clojurescript, is it ready yet?

[James Nelson]

Hi.

I'm interested in using percolator as part of my code generation process.  
I am currently exporting a generated factory which takes interfaces and 
provides black-box implementation classes;
it emits extensions of JavascriptObject for gwt, and pure java for server.

Ideally, I would like to try exporting clojure for the server, and either 
compile that into gwt-friendly format, or leave it as js.

These objects are primarily just pojos with fields, lists and maps.

Would you recommend percolator for using clojure datatypes behind the 
list/map interfaces?

Re: Smarter code reloading with tools.namespace 0.2.0

[Thomas Heller]

Hey Stuart,

I wrote a little "autotest" script which uses tools.namespace to figure out 
which tests to run. Basically I just watch the source files, when modified 
I run (refresh) and use the repl/refresh-tracker var to find out which 
tests should be executed. To do this I had to monkey-patch c.t.n.repl since 
refresh-tracker is private.

See https://gist.github.com/3865356 Line 6-15.

Works well enough, but the monkey-patch kinda bothers me, so if you feel 
like adding those functions I'd appreciate it. Maybe they are useful for 
somebody else, since Mika mentioned something similar.

Anyways, thanks for tools.namespace.

Regards,
/thomas

Re: Issues with Penumbra

[JvJ]

Another issue that was giving me trouble was that penumbra 0.6.0 appears to 
only work with Clojure 1.2 because of some issues with Contrib 
dependencies.  It looks like prismofeverything's 0.6.9 refactors it to work 
with 1.3 and up.

Re: Intern a var from outside namespace

[Stuart Sierra]

Sounds like a load-order issue. Make sure the code *creating* the 
namespaces/vars is loaded before the code *using* them.

But better yet, just don't do it. :)

Packaging ClojureScript libraries for use with Leiningen

[Conrad]

Hi, can someone point me towards some documentation as to the proper way to 
package a ClojureScript-based library that can be used in the usual way via 
leiningen?

I'm thinking I'd be able to upload it to clojars.org (as I would do for a 
Clojure library), but given that "Jars" are something Java-specific, I'm 
confused as to whether that'll work...

Can someone point me in the right direction? Thanks!

JARs are a great way to deliver ClojureScript for Clojure users - lein
or otherwise. That's how core.logic ships both Clojure & ClojureScript
versions - in a single jar.

Re: Packaging ClojureScript libraries for use with Leiningen

[Michael Fogus]

I've looked at the core.logic packaging, but it wasn't immediately
obvious what was happening.  I eventually figured it out, but it would
be nice to have a roadmap for making cross-language packaging easier,
even if the needed pieces were not yet available.

concat files after pmap

[Brian Craft]

I'm using pmap to run a bunch of compute intensive jobs that output to 
files. Afterwards I need to combine them into one file (in a particular 
order). Are there any tools to do a file concat? I found the fs library on 
github, but it doesn't appear to have a concat or append. Perhaps I should 
just drop to shell.

ANN strucjure 0.1.0

[Jamie Brandon]

Strucjure is a library for parsing and pattern matching using PEGs,
roughly modelled after OMeta.

https://github.com/jamii/strucjure

Compared to core.logic, strucjure does not perform decision tree
optimisation and probably generates worse code but it supports
first-class, recursive views and can express eg context-free grammars.

I still have lot of work to do to make this production-ready but I
wanted to get some feedback before I start comitting to the current
design.

(doseq [file input-files]

Re: Packaging ClojureScript libraries for use with Leiningen

[Kevin Lynagh]

If your downstream users are using the "lein-cljsbuild" plugin, note that 
it will automatically pick up externs and JavaScript libs within your JARs 
if you put them under

/closure-js/libs/your-project/some-js-lib.js
/clojure-js/externs/your-project/externs.js

(see https://github.com/emezeske/lein-cljsbuild/issues/95 for more details)

If are targeting both Clojure and ClojureScript you might want to check out 
my CLJX leiningen plugin which automatically does some rewrites in your 
code and spits out both .clj and .cljs files.
See 

https://github.com/lynaghk/c2/blob/master/project.clj

for a project that uses that approach.
Users can just put C2 in their leiningen deps as normal and can use it from 
clj or cljs code without having to do anything special.

Re: Rouge: Ruby + Clojure

[Arlen Christian Mart Cuss]

Hi Armando,

Thanks for giving it a go!

On second thought, I've decided against 1.8 support.  1.8 was released 
initially in 2003, and is now considered deprecated.  I gave it a solid go 
to see if the code I wrote was mostly-compatible with 1.8, but it started 
to turn into something of a dog's breakfast.

Sorry for the hassle.

— Arlen

Re: ANN subpar (paredit for codemirror)

[Anthony Grimes]

Awesome! I've been waiting for this. I'd love to see it added to refheap, 
https://github.com/Raynes/refheap. It'd be the only paredit-enabled 
pastebin on the market.

Re: ANN subpar (paredit for codemirror)

[Andrew]

After subpar's parse beast is done, the info retained is basically this

   - for any given index, what is the index for the opening delimiter of 
   the containing list? -1 if none
   - for any opening delimiter index, what are the start and end indices of 
   the children, and what is the index for the closing delimiter

I don't fully understand what you want, but my impression is that more info 
should be retained.

Re: Rouge: Ruby + Clojure

[Armando Blancas]

I didn't realize 1.8 was such and old version; will get a recent build and 
give it another try. I'm interested in scripting, so the basic pieces are 
already there. With a short startup time this will be looking really useful.
