MrBenchmark benchmarks : Opteron vs UltraSPARC IV vs UltraSPARC T1

Hi all;

Whiners came to me saying : "MrBenchmark : Enough theory, please give us some benchmark results.."
And I said, fine...so here we are ..I will publish some informal benchmark results in this forum. And Yes I will compare
UltraSPARC IV, IV+,  Opteron , UltraSPARC T1 and even Xeon !

Let me present the first microbenchmark of my serie . It is called iGenCPU. It is written in 100% pure Java. I am using Java 1.5

The iGenCPU benchmark is a JavaTM-based CPU micro-benchmark used to compare the CPU performance of different systems.
Based on a customized Java complex number library, the code is computing Benoit Mandelbrot's highly dense fractal structure using
integer  and floating-point calculations. The simplicity of the code as well as its non-recursivity allow a very scalable behavior using 
less than 64 Mb of memory per thread.

iGenCPU reports multiple statistics. We  are mostly interested in analyzing iGenCPU_Thp (how many fractals per second can we
 compute with this number of threads ?) and iGenCPU_RT (what is the average time needed to compute a complete fractal with this number of threads ?)

IgenCPU use the system this way as represented by my iTarget chart :




Next to come : our first iGenCPU benchmark result (table & diagram ): V40z (4xAMD Opteron @2.4Ghz  with 8GB RAM ) vs V490 (4xUltraSPARC IV 1.2Ghz 8GB RAM)
