Hi Alex,

I have finally installed bundle-octave* on my G5/OSX 10.5 (Atlas variant) and
intel_64/OSX 10.6 (not yet on G4/OSX 10.4). Testing octave I see the following 
warning (both systems):

octave:1> pkg load all
warning: addpath: 
/sw/lib/octave/3.2.4/packages/ocs-0.1.1/powerpc-apple-darwin-api-v37/../utl: No 
such file or directory

warning: mark_as_command is obsolete and will be removed from a future version 
of Octave

octave:2> benchmark_dtmm(1000,1000,10)
warning: fopen: file found in load path

and the following error when leaving octave on intel/10.6:

error: Permission denied
error: ignoring octave_execution_exception while preparing to exit

Now what worries me more is that benchmark_dtmm(1000,1000,10) gives

Time for A'*B (A,B m-by-n matrices): 1.72362 on a 2.53Ghz Core2Duo

and

Time for A'*B (A,B m-by-n matrices): 0.508563 on a 1.8Ghz G5

If I understand the meaning of these numbers, this means ~4GFlops
on the G5 (increasing to 5GFlops for n=m=4000, IIRC Atlas gives ~5.6GFlops
out of the peak 7.2GFlops), but only 1.2GFlops for the Core2Duo (Atlas or
the accelerated framework give ~11GFlops out of the peak 20GFlops).

1.1GFlops on my intel box corresponds to what I get when compiling lapack
with gfortran which make me suspicious that octave (plain variant) is not
linked against -Wl,-framework,Accelerate. Could someone check what is wrong
with the above (my conclusions or the lapack library used)?

TIA

Dominique
