=head1 DESCRIPTION |
| 10 |
|
| 11 |
While L<Coro> threads (unlike ithreads) provide real threads similar to |
| 12 |
pthreads, python threads and so on, they do not run in parallel to eahc |
| 13 |
other even on machines with multiple CPUs or multiple CPU cores. |
| 14 |
|
| 15 |
This module lifts this restriction under two very specific but useful |
| 16 |
conditions: firstly, the coro thread executes in XS code and does not |
| 17 |
touch any perl data structures, and secondly, the XS code is specially |
| 18 |
prepared to allow this. |
| 19 |
|
| 20 |
This means that, when you call an XS function of a module prepared for it, |
| 21 |
this XS function can execute in parallel to any other Coro threads. |
| 22 |
|
| 23 |
The mechanism to support this is easily added to existing modules and is |
| 24 |
independent of L<Coro> or L<Coro::Multicore>, and therefore could be used, |
| 25 |
without changes, with other, similar, modules, or even the perl core, |
| 26 |
should it gain real thread support anytime soon. SEe L<TODO> for more info |
| 27 |
on how to prepare a module to allow parallel execution. |
