cores is same machine reporting different bogo mips rating ?

Hi,

 

I have a machine, which is reporting 4 cpus. It is 2 AMD processors, and
2 cores in each processor.

 

The 4 cores are not reporting the same bogomips ? Should they.

 

To explain.

 

 

test_HOME> grep AMD /proc/cpuinfo

vendor_id       : AuthenticAMD

model name      : Dual Core AMD Opteron(tm) Processor 265

vendor_id       : AuthenticAMD

model name      : Dual Core AMD Opteron(tm) Processor 265

vendor_id       : AuthenticAMD

model name      : Dual Core AMD Opteron(tm) Processor 265

vendor_id       : AuthenticAMD

model name      : Dual Core AMD Opteron(tm) Processor 265

test_HOME> grep bogo /proc/cpuinfo

bogomips        : 3578.26

bogomips        : 3578.26

bogomips        : 3578.26

bogomips        : 6710.88

 

note how the last core is reporting the higher figure. As LSF seems to
take the highest figure and append to this to create an architecture, a
similar box can report as different architectures under LSF. We can
tweak LSF so they will by classed as the same, but why, and should  1
core is reporting a higher figure are the questions.

 

( LSF is the application we are using to manage jobs to this box ).

 

The version of linux running is;

 

test_HOME> cat /etc/redhat-release

Red Hat Enterprise Linux WS release 3 (Taroon Update 8)

test_HOME> uname -a

Linux test 2.4.21-47.ELsmp #1 SMP Wed Jul 5 20:30:30 EDT 2006 x86_64
x86_64 x86

_64 GNU/Linux

 

Any pointers are appreciated. 

 

Basically, is this correct behaviour ?
