[R] Does R use the ATLAS linear algebra library?

[Douglas Bates]

I should have mentioned that my timings were done on a 900 MHz Athlon
processor running Debian GNU/Linux 2.3.  The system has 768 MB of
memory.

Apparently the optimizations used in ATLAS are particularly effective
on the Athlon.  Other processors may not show such dramatic speed
gains.

I did not compile ATLAS for this machine.  I used the Debian atlas2
package which, according to the documentation, was optimized for a
Pentium II (350 MHz).  There may be some modest gains achieved by
recompiling.  I tried to recompile from the sources but the Debian
package build failed and it is too late at night to start working on
why it failed.
