Hi all,
I'm doing parallel rendering using 1 client (dual core laptop) and 2 cluster
servers (dual core desktop)
below is the timer log result i collected when i run: mpirun -np 4 pvserver
-----------------------------------------------------------------------------------------------
Local Process
Still Render, 3.029 seconds
Execute vtkMPIMoveData id: 457, 1.98248 seconds
Server, Process 0
Execute vtkFileSeriesReader id: 176, 0.637821 seconds
Execute vtkMPIMoveData id: 457, 1.49186 seconds
Dataserver gathering to 0, 0.829525 seconds
Dataserver sending to client, 0.661658 seconds
Server, Process 1
Execute vtkMPIMoveData id: 457, 0.141821 seconds
Dataserver gathering to 0, 0.141544 seconds
Server, Process 2
Execute vtkMPIMoveData id: 457, 0.243584 seconds
Dataserver gathering to 0, 0.243318 seconds
Server, Process 3
Execute vtkMPIMoveData id: 457, 0.191589 seconds
Dataserver gathering to 0, 0.191303 seconds
-----------------------------------------------------------------------------------------------------
i have difficulty interpreting the timer log, my guess is:
Scenario 1:
Process 0 reads the whole data, disseminate the dats into 4 pieces, then
distribute to itself and Process 1&2&3,
each node will process the data and send it back Process 0,
Process 0 gather all data and send it back to client,
client renders the data
Scenario 2:
Process 0 reads the whole data, distribute the whole data to Process 0&1&2&3,
each node will 'take' their own piece of data to process, then send it back
Process 0,
Process 0 gather all data and send it back to client,
client renders the data
Which scenario is the correct one? or both are wrong?
is there any resources i could refer to find what does it mean by: Execute
vtkFileSeriesReader, Execute vtkMPIMoveData?
any help / feedback is highly appreciated!
thanks!
regards,
chewping
