By giving a quick look at the runtime libraries, I don't think the
problem is related to these:
dapper:
atlas3-base (3.6.0-20)
lapack3 (3.0.20000531a-6ubuntu2)
refblas3 (1.2-8ubuntu1)
edgy:
atlas3-base (3.6.0-20.2)
lapack3 (3.0.20000531a-6ubuntu2)
refblas3 (1.2-8ubuntu1)
the only differences between the two atlas3-blase libraries being in the
packaging (and of course the base libraries against which they were
compiled).
Unless there is a copy&paste problem, these results:
athlon/dapper max= 2.28048070053e-16 min= -4.583786292e-16 GOOD
pentium/edgy max= 2.28048070053e-16 min= -4.583786292e-16 GOOD
seem to confirm it.
I guess in both cases you were using the 32bit version?
It could actually be an hardware problem, would it be possible to test this on
the same machine with the two different versions (edgy and dapper)? Perhaps
some of the test cases above covers this?
