hy it is not possible to use the "The MPI Extensions" (yellow book)
Client-Server example?!?!?!?
In MPICH2 this example works properly.
I
have compiled with Open-MPI mpicc properly the program without error
and later I have execute it.
I have many problems with the
MPI_LOOKUP_NAME that returns to me this error message:

*** An error
occurred in MPI_Lookup_name
*** on communicator MPI_COMM_WORLD
***
MPI_ERR_NAME: invalid name argument
*** MPI_ERRORS_ARE_FATAL (goodbye)
[0.0.0]-[0.1.0] mca_oob_tcp_msg_recv: readv failed with errno=104

The
server publish its name without error but inside the client the
Lookup_name routine give me the above error. WHY?

Help me!!!
