I just returned to this list -- what is the "new infrastructure" we are |
2 |
"preparing for"? |

BTW, I am also on the Atlas mailing list. There was quite a bit of |
5 |
activity over the weekend regarding GCC 4. It seems the default Fortran |
6 |
in GCC 4 is Fortran 95, which has instilled great trepidation in some of |
7 |
the "old-timers" on the Atlas list. In any event, should I wish to |
8 |
experiment with GCC 4, how do I go about doing so without creaming my |
9 |
system? Do I need a whole new machine/partition? |

The good news is that Gentoo is *way* better than Debian or Fedora in |
12 |
its behavior re Atlas. Atlas is *designed* to tune itself to your |
13 |
machine, and the Debian packages, for example, are *way* out of date and |
14 |
compiled seperately for each architecture. I don't think I'll ever pry |
15 |
Dirk Eddelbuettel away from Debian, but there's a lot of hope for the |
16 |
rest of the scientific computing community, at least those who want a |
17 |
working Atlas out of the box. :) |

Other notes: R. Clint Whaley, the head of the Atlas project, mentioned |
20 |
that he was interested in making shared libraries of Atlas. I told him |
21 |
that the Gentoo package already did that for BLAS-Atlas and LAPACK-Atlas. :) |
22 |
|
23 |
Could we get a "testing/unstable" Atlas in Portage? Right now, they are |
24 |
at 3.7.10, and I only see a 3.7.10 for blas-atlas, not for atlas itself |
25 |
or lapack-atlas. I think the x86-64 users will want 3.7.10 across the |
26 |
board, and might also want to be able to compile selected code with GCC 4. |
