Rotation about the X axis of the Lorenz attractor (5000 iterations), computed simultaneously on two different computers [*Rotation autour de l'axe X de l'attracteur de Lorenz (5000 itérations), calculée sur deux ordinateurs différents*].

The Lorenz differential equation system is solved 128 times for exactly
the same initial conditions. Each one of the 128 computations is run either
on the computer A or on the computer B, depending of their instaneous
work load. Computers A and B are identical except for their system release. To
distinguish the 128 different computations, each one has its own point
of view (using a 3D rotation applied after the computation). For 1000 iterations
(see "Rotation about the X axis of the Lorenz attractor (1000 iterations), computed simultaneously on two different computers"), the resulting animation shows no defect,
when for 5000 iterations (see "Rotation about the X axis of the Lorenz attractor (5000 iterations), computed simultaneously on two different computers"), it appears clearly that
the two computers did not give the same results.
