You may recall ATLAS dumped core on 't2' until a work-around suggested
by the main atlas developer was applied. I had applied this patch on all
Solaris systems, but since the problem has not been observed on older
Solaris systems, I think it's better to just apply it to the newer
machines based on the sun4v architecture.
By only applying the patch on this architecture, older systems will be
tuned better.
It should be very simple to review, as the change is only one line of
code, from:
if os.uname()[0] == 'SunOS':
to:
if os.uname()[0] == 'SunOS' and os.uname()[4] == 'sun4v':
based on the output of os.uname()
kir...@t2:[~] $ python
Python 2.4.4 (#1, Jan 10 2007, 01:25:01) [C] on sunos5
Type "help", "copyright", "credits" or "license" for more information.
>>> import os
>>> os.uname()
('SunOS', 't2', '5.10', 'Generic_141414-02', 'sun4v')
