[mpich-discuss] MPI run error

[Jayesh Krishna]

Hi,
 Which version of MPICH2 are you using ? The latest stable release of MPICH2 is 1.3 (http://www.mcs.anl.gov/research/projects/mpich2/downloads/index.php?s=downloads). If you are not at the latest stable release version, please uninstall any previous versions and install the latest version.
 If upgrading to the latest version does not solve your problem please try the following,

# Check the status of the process manager, SMPD, using the command, "smpd -status"
# Try running a simple non-MPI program like hostname (mpiexec -n 2 hostname)
# Try running your job using the command, "mpiexec -n 2 lmp_win_mpi -in in.graphene"

 Let us know the results.

Regards,
Jayesh

To whom it may concern:

 

I am attempting to run the LAMMPS MD software on two processors on my
machine but the target machine refuses connection.  I have installed MPICH2
and have put the necessary executable files in the same directory as my
simulation input file, etc.  

 

When I go to run the software, I enter the following command in the prompt

 

"mpiexec -np 2 -localonly lmp_win_mpi -in in.graphene"

 

And get "Unknown option: -d

 

Error while connecting to host, No connection could be made because the
target machine actively refused it.  (10061)

 

Connect on sock (host=ETL5, port=8676) failed, exhausted all end points

Unable to connect to 'ETL5:8676'

sock error: Error = -1"

 

Any suggestions?
