<p>Just for information: the -DHAVE_LIBMVEC is a preprocessor
option (like -DINTEL_VML for ifort) and will speedup the HAMILT
part due to a vectorization of cosine/sine functions.<br>
</p>
<p>As far as I remember, it is available only with more recent
gfortran/openblas versions, therefore not yet a "default" gfortran
option.</p>

<p>Hi Pavel,</p>

<div>I don't think that that compiler flag has been used:</div>
<div><span style="font-family:monospace"><span
style="color:rgb(0,0,0)"> </span></span><span
style="color:rgb(0,0,0);font-family:monospace">$ find . -name
"Makefile" -exec grep "DHAVE_LIBMVEC" {} \;</span></div>
<div>yields nothing in my Wien2k source directory.</div>

nice, ~30 seconds instead of ~150 :-)
BTW is this already with "-DHAVE_LIBMVEC" in compiler options?
