<font face="Dialog" size="2">I try the example programm with no params that's why i chrashed , yes ok, but how can i prevent the users to do the sane as i did . Currently i try with limit maxproec 128 (not 16 000 as default parameter) on the command line.I didnt test it right now becouse i have to be sure that nobody is on the machine exept me otherwise :-( my boss will cut me into pieces.</font> </p>

If you switch to one of them you will get both<br>great performances and all core being used during matrix computations.<br>* GPGPU: you can give a try to our GPGPU extensions (don't hesitate if<br>you have any feedback). [1]<br>* If you are more into grid/cloud computing, you can give a try to proactive<br>[2]<br>* In Scilab, even it is a bit outdated, you will find a PVM interface [3].<br>* Finally, if you are familiar on the build process of an linux application,<br>you can try with the MPI implementation of Scilab (in the git branch "MPI")<br><br>Hope this helps,<br> </p>
