Hi Carlo<br>
<br>
Running your input (only the first 6 SCF step) on blanc (16 prcs) gave<br>
me the following timings<br>
<br>
655.19 s (cp2k from 17.8.09)<br>
692.53 s (cp2k from 6.11.09)<br>
<br>
there is clearly a slow down in the dbcsr_sm_fm_multiply that we are<br>
working on.<br>
I suggest you to use the other OT which is faster, i.e.<br>
<div class="im"><br>
&OT<br>
PRECONDITIONER FULL_SINGLE_INVERSE<br>
</div> ALGORITHM IRAC<br>
ORTHO_IRAC CHOL<br>
EPS_IRAC_SWITCH 0.0E0<br>
MINIMIZER CG<br>
&END<br>
<br>
with that I get<br>
<br>
602.71 s (cp2k from 6.11.09)<br>
<br>
... even with about 40 s slowdown in the dbcsr_sm_fm_multiply routine.<br>
<br>
V<br>
<br>
