Hi all, I am using meep-mpi to simulate some simple 3-D SOI photonic crystal based structures on my PC. It has an i7-930 Quad-core CPU @ 4 GHz. My problem is, while I use command
mpirun -np 4 meep-mpi *****.ctl each core will run the code alone, they do not share the work. So each step will be run four times, a code that took 90 sec on one core now takes more than 100 sec using all four cores. Now I'm running resolution 32 codes that takes more than 30 hours. In this case, parallel computation will be of great help. Has anyone met similar problems or do you have any hints on what might go wrong, please? Thank you. Boshen Gao
