Benchmark - cpus

Simple benchmark, just floating point calculations.
This can be use to evaluate the performance on Monte Carlo application and numerical recursions without memory use.
We calculate the time for 10^9 m=tanh(ran2(&seed)*m), m=sin(ran2(&seed)*m) and if(ran2(&seed)). (seed=234)
Used cpus in decreasing performance order :

Intel(R) Core(TM) i5 CPU 750 @ 2.67GHz
AMD Phenom(tm) II X4 945 Processor @ 3GHz
Intel(R) Xeon(R) CPU X5550 @ 2.67GHz
AMD Athlon(tm) 64 X2 Dual Core Processor 4000+ @ 2.1GHz
Intel(R) Core(TM)2 Quad CPU Q6600 @ 2.40GHz - Chipset ICH10
Intel(R) Core(TM)2 Quad CPU Q6600 @ 2.40GHz - Chipset ICH7

Intel(R) Core(TM)2 Quad CPU Q9300 @ 2.50GHz - Chipset ICH9
Mobile AMD Sempron(tm) Processor 3500+ @1.8 GHz
Intel(R) Core 2(TM) CPU T7200@ 2.0Ghz



Below graph (incomplete) shows time versus cpu for the if(ran2(&seed)) routine

Ficou legal a figura Maicon!
Agora é só tu descobrir porque que o q9300 não ficou bem nos testes! hehe
