Hi,

More Ubuntu 64 bit platform trivia. Compiling against atlas3 provided
with Ubuntu allows scipy.test to run without error (including
lib.lapack.test() obviously).
I suppose there must be something wrong with the compilation of lapack
or ATLAS then. Maybe a problem with 3.7.11. Etc etc. Dammit, what a
way to spend your day.
Incidentally, scipy.test(10) still dies at scipy.linalg with:
Finding matrix determinant
==================================
| contiguous | non-contiguous
----------------------------------------------
size | scipy | basic | scipy | basic
20 | 0.20 | 0.28 | 0.23 | 0.30 (secs for 2000 calls)
100 | 0.32 | 0.45 | 0.38 | 0.53 (secs for 300 calls)
500Illegal instruction
This error does not occur with my home-compiled atlas libraries. AMD
specific compile for Ubuntu atlas maybe?
Best,
Matthew
