Public bug reported:
Hi!
I'm running Ubuntu 12.10 x86-64, and I recently tried to replace ATLAS
with OpenBLAS on my system. I was hoping to get a speedup on my
computations (which I'm performing using python-numpy). I did:
sudo apt-get remove libatlas3gf-base libatlas-dev
sudo apt-get install libopenblas-dev
However, it would appear that something went wrong:
$ python -c"import numpy; x = numpy.random.random((1000,1000)); numpy.dot(x, x)"
Illegal instruction
$ tail /var/log/syslog -n 1
Feb 11 14:00:28 xua kernel: [ 456.729279] python[12206] trap invalid opcode
ip:7f3b48b57220 sp:7f3b4506ecf8 error:0 in
libopenblas.so.0[7f3b47d18000+127e000]
According to `apt-cache show libopenblas-bas` it is decided at runtime which
kernel will be run. It looks like in my case (AMD Bulldozer, FX-8150) it tries
to run the wrong kernel. Any help would be appreciated.
