Does VTune work with AMD Opteron processor?

Hi,
I recently downloaded VTune 3.0 for Linux for evaluation and when I tried to install it on an IBM Server with dual AMD Opteron processors, it complained that the processor typeis unsupported.
Here is what I havein cpuinfo
processor : 0
vendor_id : AuthenticAMD
cpu family : 15
model : 5
model name : AMD Opteron Processor 250
stepping : 10
cpu MHz : 2392.588
cache size : 1024 KB
fdiv_bug : no
hlt_bug : no
f00f_bug : no
coma_bug : no
fpu : yes
fpu_exception : yes
cpuid level : 1
wp : yes
flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 syscall mmxext lm 3dnowext 3dnow
bogomips : 4771.02
processor : 1
vendor_id : AuthenticAMD
cpu family : 15

I have RH 7.3 installed on my servers and the kernel is 2.4.18-5smp.
Thanks in advance,

Hey Subhash,
Exactly so: the new VTune analyzer software does not support AMD processors. You won't be able to use it.

This is because previous versions of VTune analyzer did not fully function on non-Intel CPUs because of the differences in the Performance Monitoring Units (PMU) among the different processors. Event Based Sampling (EBS), the most powerful feature of the VTune analyzer, did not work because of these differences. Callgraph functioned partially depending on the instructions being used, some code worked and other opcodes did not. In order to prevent the bad user experience that results from this difference in technology, we have decided to only support Genuine Intel Processors that we have tested.
