Re: [SciPy-user] install - floating point exception (scipy-tests)
Hi all, Thank you Andrew, my processor has indeed SSE support. It is an AMD Opteron 64-bit. I will install a patched libc6 debian package from your site, and let you know. Jean Pierre python@axtom.com wrote:
Hi all,
I have installed scipy, and have some fp exceptions when running the tests. Does anyone else experiment the same thing?
GNU libc version 2.3.2 has a bug "feclearexcept() error on CPUs with SSE" (fixed in 2.3.3) which has been submitted to Debian but not fixed in sarge. See the following URL for more info, including links to the above bug reports and patched .debs: http://www.its.caltech.edu/~astraw/coding.html#id3 -- Jean Pierre

Hmm. Are you running with amd64 architecture or the i386? I haven't found that patch to be necessary on amd64. If it is, you'd have to rebuild the .debs -- the binaries are only compiled for i386. (The bug certainly does affect the i386 architecture, though...)
Just another data point: I'm running new numpy/scipy on a cluster of Opterons with Debian AMD64 unstable (with the AMD64 Atlas .debs) and have not seen this problem. Scott On Friday 28 April 2006 14:11, Andrew Straw wrote:
