C/C++ MPI speedup is not as expected

问题 I am trying to write an MPI application to speedup a math algorithm with a computer cluster. But before this I am doing some kind of benchmarking. But the first results are not as much as expected. The test application has linear speedup with 4 cores but 5,6 cores are not speeding up the application. I am doing a test with Odroid N2 platform. It has 6 cores. Nproc says there are 6 cores available. Am I missing some kind of configuration? Or is my code not prepared well enought ( it is based
