Hi,
I've configured a cluster with meep-mpi. I am able to execute the code. But the
code while run with '-np 1' is completely run within 368 seconds where it took
410 seconds while run with '-np 2'. Similarly, the time keeps increasing for
increasing number of processors which is not expected.

Hi, I believed you might have problems with the inter-node communication in
the cluster; I wondered whether the problems pertain when the
multiprocessing is run on single node. Maybe you have
Dear Ratnesh,
Can you check outputs of your simulations when you were using two cores
(-np 2)? Did meep-mpi run simulation for each time point twice?
Alternatively you can save outputs into a file and email them to me.
best wishes
