[Paraview] to be sure about used hardware ...

[Ufuk Utku Turuncoglu (BE)]

Hi Armin,

Actually, the data size is 541x385x40 (x,y,z; float) ~8.3M grid points 
and i am using regular grid not unstructured. I will give a chance to 
wavelet source as you suggest to get feeling about the performance but i 
am still looking for an answer for my initial question. Is out of box 
ParaView binary could use full capability of hardware or not?

Thanks again,

--ufuk
