About paralelization why use a interpreted language like Scilab? Are there some advantages? To numerical optimized algorithms I prefer use a compiled language one, to numerical application my favourite is Fortran. For such applications a compiled code run much more faster than an interpreted one like Matlab and Scilab. If you want to run this aplication paralely probably it is too optimised and full of iterations.<br><br>In a algorithm to the method FDTD to eletromagnetism use an interpreted language is inviable if you want more than dozens of thousands of iterations. Codes written in Fortran are easy to paralelise using an API called OpenMP.<br></div><div style="font-family: times new roman,new york,times,serif; font-size: 12pt;"><br><div style="font-family:
