Subject: How to write efficient threaded programs on OCaml
Date: Wed, 08 Feb 2006 00:15:47 +0100 (CET)	[thread overview]
Message-ID: <20060208.001547.81488614.Christophe.Troestler@umh.ac.be> (raw)

Hi,

I was wondering if some among you would like to share some hints about
how to write efficient multithreaded applications in OCaml.  Indeed,
for example, the following concurrency test shows OCaml performing
quite poorly:
http://shootout.alioth.debian.org/debian/benchmark.php?test=chameneos&lang=all
A qprof profiling reveals that OCaml is spending 63-73% of its time on
the function caml_process_pending_signals and 13-18% on
pthread_cond_signal.  Is there a way to improve the performance of
this code ?

Now maybe this is not to be considered like a good analogous of a
possible "real life" application.  Hence my question: what do people
do to get decent performance in these cases?

Cheers,
ChriS
