[modeller_usage] Differences using Xeon vs Opteron systems

[Robert Healey <>]

Hello.

I'm the systems administrator for a research lab using Modeller 9v3. 
I've installed the x86_64 RPM file on a pair of Xeon X5355 based systems 
and some Opteron 6136 based systems.  The researchers are reporting 
getting radically different results between these two systems.  I've 
done some testing and Opteron 252 based systems give the same results as 
the Opteron 6136 systems and Xeon X5570 systems give the same results as 
the Xeon X5355.

I'm working on getting a set of results I can post, but has anyone seen 
anything like this before?  I was being shown summaries where the final 
results were different in value by 1.5

Thank you.
