Dear all, |
2 |

I recently submitted a question to the R-help mailing list, because I |
4 |
noticed that matrix multiplication was giving me trouble (basically, that |
5 |
there were some times when a result was NaN): |

As it is mentioned in the end of the thread, the solution was to recompile |
10 |
R against the reference blas and lapack libraries, and avoid the atlas |
11 |
that I was using. |
12 |
|
13 |
So it seems that the problem is not R-related, but atlas-related, and |
14 |
linked to gentoo, I would like to share the problem with you, just in case |
15 |
somebody has any clue on what is wrong with atlas. |
16 |
|
17 |
Although I have firstly used a very aggressive cflags to compile atlas |
18 |
(-Ofast), I suspected that the problem was that, but I recompiled atlas |
19 |
using -O2 and the problem still presists with atlas, but is solved with |
20 |
reference. |
21 |
|
22 |
I am using atlas-3.9.23-r4, R-2.13.1 and gcc-4.6.1 |

Thank you, |
