Dear all, I am facing with a fatal MPI error while I am building an Adaptive Mesh Refinement library, which is Chombo, to my personal computer. The error message is "MPI_ERR_ARG: invalid argument of some other kind". The error output is also attached. I couldn't figure out what causes this error and how to solve it. I am using Ubuntu 16.04 operating system and MPICH 3.2 together with HDF5 1.10.1. I am very much appreciated with your help.
