Sorry for such pedestrian misprint.
Corrected, the configure ended with error:
"Expected file /usr/lib/include/numa.h"
In debian amd64 lenny it has a different location:
"/usr/include/numa.h"
Can the configure script be modified safely to account for the
different location?
thanks

As far as I understand,
apt-get install libnuma1 libnuma-dbg libnuma-dev
installs libnuma libraries 64 bit in /usr/lib there also two symlinks
/usr/lib32 and /usr/lib64 but there is no trace of the libnuma
libraries there.
That the computational codes I use run twice as fast at 64 bit than 32 bi

You may need to ask somebody else or google around
about the relative performance of 32-bit vs. 64-bit mode.
It is worth trying 64-bit. The performance is going to depend on the
program. Since 6
Hi Francesco, list
I was thinking of compatibility (and consistency)
rather than of performance.
I don't know about Debian, but on CentOS 5.2 x86_64
the 64-bit libnuma library lives at /usr/lib64,
and the 32-bit version on /usr/lib.
If you are trying to build 64-bit OpenMPI libraries with libnum

Does this imply that a compilation with "--with-libnuma=/usr/lib64"
may afford better performance?
Am asking that because in the meantime I have taken previous
compilation of openmpi-1.2.6 and use it (one disk of raid1 died and I
changed both with larger ones). If better performance I can
Hi Francesco, list
Francesco:
Besides the typo that Jeff found on your
CXX definition, I would guess you want
--with-libnuma=/usr/lib64
(since your machine is amd64,
and you are using the 64-bit Intel compilers: cce, fce).
That is instead of --with-libnuma=/usr/lib (32-bit).
