Subject: [OMPI users] a question about mpirun

hello all :

       I installed the openmpi-1.4.3 on redhat as the following step :

       1. ./configure --prefix=/data1/cluster/openmpi
  
       2. make

       3. make install

       And I compiled the examples of openmpi-1.4.3 as the following step :

       1. make

        Then I run the example :

            ./mpirun -np 1 /tmp/openmpi-1.4.3/examples/ring_c

        I get the following error :

-----------------------------------------------------------------------------
It seems that there is no lamd running on the host node1.
This indicates that the LAM/MPI runtime environment is not operating.
The LAM/MPI runtime environment is necessary for MPI programs to run
(the MPI program tired to invoke the "MPI_Init" function).

Please run the "lamboot" command the start the LAM/MPI runtime
environment. See the LAM/MPI documentation for how to invoke
"lamboot" across multiple machines.
-----------------------------------------------------------------------------
     
       I run openmpi , but I get the error from lam-mpi . why ? Can you help me ?

       Thank you !
