<div>Thank u very much for kind response.I am trying to follow each step one by one,first by installing MPI.Actually the examples in parallel directory is a bit confusing.When I did program using simple C with MPI,I have complete control on how to divide the data to each processor.But those examples in parallel does not say about that.Suppose I have cut my 3D data to three pieces and distribute those to 3 different processors and those three processors manipulate the data and if necessary communicate other processors.Can anyone help me with such simple Hello type program so a novice like me can understand how MPI works with VTK?VTK with MPI is seems more complicated,abstract than MPI with simple C.</div> <div>Thanks,</div> <div>Wei.<BR><BR><B><I>Kent Eschenberg <eschenbe@psc.edu></I></B> wrote:</div> <BLOCKQUOTE class=replbq style="PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #1010ff 2px solid">Hi Wei,<BR><BR>I just
