[Octopus-users] timings on sgi altix

[Sébastien Hamel]

Hi!

I would like to have your timings for the time-dependent calculation of benzene

On an sgi altix, compiled with -O2 -tpp2 I get:

about 3s/time step when my grid has 11000 point (small cylinder 9f 6A radius and
0.53 A XLength) but around 2000 iterations these step take 200s for 30
iteration and then back to 3s (I should own the 100% of the cpu) 

about 16s/time step when my grid has 113000 point (sphere of 6A radius). rates
stay constant for the whole calculation

cheers
