[maker-devel] WARNING: Multiple MAKER processes...

[Jenny Barna]

We have had maker since 2010. Maker 2.10 and 2.11 compiled with mpich2
were and still are working with mpi as far as I can tell. These have
a binary called mpi_maker.

I have kept the same mpich2 installed to try to make sure things stay 
working. It has been picked up by subsequent maker builds.
It is mpich2-1.2.1p1 .

I have seen the posting by Marc P. Hoeppner on 10/26/13 about
'WARNING: Multiple MAKER processes have been started in the same
directory.' which is the same warning I have had.

Trying all my previous installations I now see this is happening in all 
2.2? distributions I have. Versions 2.10/2.11 are not doing this. 
It is happening with 2.2?/2.30p where no separate mpi_maker binary is made.

Trying new mpich 3.0.4 as advised in the posting by Marc has not worked. 
It appears to build but fails at once with severe mpi errors. Tests included
with that mpi distro worked.

I am aware the maker WARNING behaviour is indicative of mpi types having 
become mixed but have not been able to correct.
