Ok, I found the announcement. Synopsis:
----------------%<----------------
use PDL;
set_autopthread_targ(4); # Make 4 threads.
set_autopthread_size(5); # Split elements above 5 Mb.
I think this is actually 5 MB (not Mb, bytes not bits).
$a = zeroes(5000,5000); # Create 25Meg element array
$b = $a + 5; # Processing is split up into threads
$c = maximum($a);
----------------%<----------------
Interesting. Does this work for all operations like matrix
multiplication? I wonder if John had to change the implementation of
each individual function to make this work.
Daniel.
