[PPL-devel] Multithreading Convex Hull

[Enea Zaffanella]

Hello Oskar.

The PPL is not using multithreading in its own computations.

I have worked on a (conditionally) thread-safe version of the library, 
which is available in the git branch "devel".
The support for thread-safety needs to be enabled at configuration time 
(--enable-thread-safe).
Beware that the standard allocation library may become a bottleneck, so 
that you may want to switch to TCMalloc.

See the following messages for a few hints about using PPL services from 
multiple threads:

Feel free to ask questions if you face problems.

Cheers,
Enea.
