Hi all,<BR>
<BR>
I'm doing parallel rendering using 1 client (dual core laptop) and 2 cluster servers (dual core desktop)<BR>
below is the timer log result i collected when i run: mpirun -np 4 pvserver<BR>

<BR>
i have difficulty interpreting the timer log, my guess is:<BR>
<BR>
Scenario 1: <BR>
Process 0 reads the whole data, disseminate the dats into 4 pieces, then distribute to itself and Process 1&2&3,<BR>
each node will process the data and send it back Process 0,<BR>
Process 0 gather all data and send it back to client,<BR>
client renders the data<BR>
<BR>
Scenario 2:<BR>
Process 0 reads the whole data, distribute the whole data to Process 0&1&2&3,<BR>
each node will 'take' their own piece of data to process, then send it back Process 0,<BR>
Process 0 gather all data and send it back to client,<BR>
client renders the data<BR>
<BR>
Which scenario is the correct one? or both are wrong?<BR>
<BR>
is there any resources i could refer to find what does it mean by: <SPAN lang=EN>Execute vtkFileSeriesReader, Execute vtkMPIMoveData?</SPAN><BR>
