Hi,<br><br>I have till now successfully used openMPI and gromacs together. Recently I got a cluster where I tried to install openMPI and gromacs locally as I donot have root priviledges on it. But it turns out that it already has MPI environment on it (LAM) which I donot want to use (as the version is quite old.. the cluster still has gcc-3.2.3!).<br clear="all">
So after installing openMPI 1.3 and gromacs 4.0.4 on it (in my /home folder), I tried to execute:<br><br>$/home/openmpi/bin/mpirun -np 4 mdrun_4_mpi -s eql_mpi.tpr -o eql_mpi.trr<br><br>It gives the following error:<br><br>
-----------------------------------------------------------------------------<br>It seems that there is no lamd running on this host, which indicates<br>that the LAM/MPI runtime environment is not operating. The LAM/MPI<br>
runtime environment is necessary for MPI programs to run (the MPI<br>program tired to invoke the "MPI_Init" function).<br><br>Please run the "lamboot" command the start the LAM/MPI runtime<br>environment. See the LAM/MPI documentation for how to invoke<br>
"lamboot" across multiple machines.<br>-----------------------------------------------------------------------------<br><br>My question is - Why it still tries to look for LAM environment or lamd? I will be extremely thankful if somebody gives a hint.<br>
