[scilab-Users] possible to select a core ?

[Michaël Baudin]

  Hi,

There is no reason to wait, as the parallel_run function is available in 
the 5.3.0-beta-2 release :

http://www.scilab.org/products/scilab/download/5.3.0-beta-2

Many examples are provided in the help page. In this beta release, the 
parallel_run function works under Linux. A project is currently active 
for its implementation on Windows.

Best regards,

Michaël Baudin
