The problem may be the reader that you're using. Some of the readers in VTK are not parallel so even if you run multiple processes each process will still try to load the entire dataset in that case.<br><br>Andy<br><br>

<div>Hi all:</div>
<div> First thanks for Dave.Demarle's help.</div>
<div> I use "mpirun -np 4 ./pvserver" to launch a server with four nodes, visualizing a 800*800*300 grid. It seems that each process consume too much memory. So I extend the number of nodes from 4 to 8 using "mpirun -np 8 ./pvserver" , but each process on 8 nodes server consume the same memory as 4 nodes server. The situation of 16 processes(16 nodes) is same as above.</div>
<div> I thought that with the number of processes' growth, each process on server would share less raw data, so the quantity of memory each process consuming would decline. It proved that I was wrong. Could someone tell me the reason?</div>
<div> Thanks for your help:)<br> Pan Wang<br></div><br><br><span title="neteasefooter"></span><hr>
