Hi!

Thanks a lot for the answer.

Anyway, I would like to go a bit deeper on this subject. I know that there
are this kind of problems in every processor. I know that the number 39 is
the one of real concer. But we also know that still it seems to NOT have a
fix, work around ou bios update for it. So I would like to know if this is
of real concern in the field of clustering and beowulfs, and what are the
impressions people are having on these processors (and what kind of
"way-around" is being used).

Thanks a lot in advance for everything,

Sincerally yours,

Jones
