[Beowulf] Faulty Single Core Opterons - Can Overheat, Cause Floating Point Errors

[Chris Samuel]

Hi folks,

http://www.amd.com/us-en/0,,3715_13965,00.html

AMD has identified, and subsequently corrected, a test escape that occurred in 
our post-manufacturing product testing process for a limited number of 
single-core AMD Opteron™ processor models x52 and x54. No other single-core 
AMD Opteron processors, and no dual-core AMD Opteron processors, are 
affected.
[...]
You must be operating single-core AMD Opteron x52 (2.6 GHz) or x54 (2.8 GHz) 
processor-based systems, AND you must be running floating point-intensive 
code sequences.
