</div>Can anyone give me an example of why on earth anyone would need a<br>
very high throughput random number generator?<br>
<br>
I can understand why things like monte-carlo simulations and ray tracing<br>
might need a lot of random numbers, but for them PRNG in the program<br>
(e.g., rand(3)) is perfectly fine, and very fast - and there is no need<br>
for any of these super-duper super-secure generators in the kernel or<br>
the CPU...<br>
