The "Simple" example does not run on a serial machine

Hi @PetrKryslUCSD,

GridapDistributed.jl scripts can be either run in "sequential" or MPI-parallel mode.

You should be able to run in both modes, even if you do no have access to a parallel machine. In the former mode, you just replace mpi by sequential in the prun call, and execute the julia script as any other julia sequential script.

The instructions for executing a script that follows MPI-parallel mode of execution (like the one in the Simple example section) are available in the README section https://github.com/gridap/GridapDistributed.jl#mpi-parallel-julia-script-execution-instructions right below the example. The error you are getting is because you should execute the script with mpiexecjl with as many MPI processes as the number of parts (4 in the case of the example). We decided to put the example in the MPI-parallel mode (instead of sequential mode) because this is the kind of execution mode which is ultimately more useful for GridapDistributed.jl users.

I will made all this more clear in the README.md of the package.

Thanks for reporting!
