Hi,<br>
<br>
There is no reason to wait, as the parallel_run function is
available in the 5.3.0-beta-2 release :<br>
<br>
<a
href="http://www.scilab.org/products/scilab/download/5.3.0-beta-2">http://www.scilab.org/products/scilab/download/5.3.0-beta-2</a><br>
<br>
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. <br>
<br>
Best regards,<br>
<br>
Michaël Baudin<br>

Hello,<br>
<br>
The upcoming 5.3 version will have a parallel_run function. I have
never used it (and the help in the beta seems complicated) but you
may
have a look at it.<br>
