As the error message indicates, you need to run the lamboot command first. The lamboot command is used to start the LAM run-time environment. Then you can run MPI programs. When you're done with the LAM run-time environment, you run the command "lamhalt" to shut it down. PBS scripts to run LAM programs typically look like:
lamboot -v $PBS_NODEFILE cd ~/cluster/biomap mpirun N biomap lamhalt (where "N" expands to running on all available nodes, since you don't know how many nodes were in $PBS_NODEFILE) On Thu, 3 Apr 2003 [EMAIL PROTECTED] wrote: > When I try to run mpirun within a PBS script I get the following message in my > error file: > > It seems that there is no lamd running on this host, which indicates that the > LAM/MPI runtime enviornment is not operating.
