[Scilab-Dev] Performance tests - Scilab 5.3.0 Vs Scilab 5.3.0-SSE3

[Michaël Baudin]

Hi,

These results are interesting. I updated the Tutorials page on the wiki, 
in the section "Comparison of scientific technical softwares", which is 
the "benchmark" section of this page.

Obviously, the Intel MKL already brings most of the speedup for linear 
algebra, which leaves only a small space for other optimizations in this 
field.

Do we agree on the conclusion that there is only a slight advantage, 
i.e. < 1%, on these tests for Scilab/SSE3 ? What specific processor 
instructions are brought by SSE3 that Scilab (actually the compiler) 
could may use of ?

Best regards,

Michaël
