[mpich-discuss] Internal Error: invalid error code 409e10 (Ring ids do not match)

[Lu, Huiwei]

Hi Kuba,

Since it works with both Open MPI and BGP, it is most likely a problem of your MPICH installation or your platform.

We have stopped supporting the Windows platform a while ago due to lack of developer resources. Please refer to our FAQ for more information:
http://wiki.mpich.org/mpich/index.php/Frequently_Asked_Questions#Q:_Why_can.27t_I_build_MPICH_on_Windows_anymore.3F

If it is on windows platform, we recommend you use Microsoft MPI, which can be found here: http://msdn.microsoft.com/en-us/library/bb524831(v=vs.85).aspx

We also encourage you to use the latest MPICH on Linux or OSX platforms, which can be downloaded here: http://www.mpich.org/downloads/
