Here is the experimentation of the optical pendulum at its true rhythm
on a Dell Precision T3400 computer, Intel Core2 Quad Q6600 (2.4 GHz,
FSB 1066 MHz, 8 MB L2 cache, four cores)...

It is a machine which hosts GNU/Linux Mageia 8 in its 32-bits version,
and that is used to the maximum performances, thanks to multi-processing
and charge load balancing on the four cores. The calculation rate of the
eight movement parameters is at the time order of a second. Hardware
acceleration of algorithmic processing is envisaged.

Regards,
