Res: [scilab-Users] Parallel computation - grid creation

[Pedro Ledoux]

Hello. 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.

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.

Hello,

I once set up small cluster in my lab. I found 2 "cluster" distributions that 
may help you.

I know that OSCAR (http://oscar.openclustergroup.org/) automatically ste up PVM. 
Nevertheless the project seems to have difficulties to deliver a stable version 
for the 6 branch.

You may also have look at ROCKS (http://www.rocksclusters.org/wordpress/) which 
seems more dynamic (but I don't know of it has PVM included).

I have never used PVM with scilab so I can't help you with this. I know that 
there is a compile time option to enable it. Maybe the default version has 
PVM...
