[Scilab-users] libsciparallel.so not provided

[paul.carrico at free.fr]

Hi Sylvestre,

Let me asking the following : in order to use parallelization in a multicore environnent (serveur or station), what is the best way ?

NB : 
- As I ever told in the current list, I use as often as possible the vectorization in my current develoment, but the same elementary scheme has to be used tens of hundreds times ... thus parallization is another way to have significant gain in time calculation,
- I've a CentOs server with 8 processors

Paul

.libs is the temporary directory used under GNU/Linux and Mac OS X at
build time to store the shared library (.so, .dylib).
Your issue has been reported here:
http://bugzilla.scilab.org/show_bug.cgi?id=12133
and I will see if I can fix it for 5.4.1.

About PVM, Paul, you can give it a try. PVM is a bit outdated and not
maintained. We are working on a MPI Scilab implementation which should
be better.

Otherwise, if you want to go into parallel, you can have a look to Diet:

or proactive:
