problem in the CFX12.1 parallel computation
I am using the LINUX CFX12.1 parallel computation to modeling an axial compressor flow. The total grid elements is about nine million. Eight computers were used with a HP MPI distributed parallel.
The problem is that the computation stopped at about 40th step, with no error pop out. I am sure the CPU and memory is sufficient for the computation, but why i got the interruption?
Another problem is that should I do anything when I manually stopped a MPI parallel computation. I find that, the computation become slow when it is started after a parallel computation stopped.
Problem has been figured out in the CFX12.1 parallel computation, Thank you~
I choose the partition type to "uniform" and then the problem dissappears~
I have a question to ask.
I'm using the same CFX and I want to use a supercomputer with 4nodes*4 ppn= 16
my problem is that when I use serial it solve about 12 iterations per hour.
when I use any parallel or Distributed parallel the speed is slowerrrr.. 2 iterations per hour.
do you know why?
