Hi Users:
I install amber on a SGI Altix 350. When I try to run a job in parallel or try
to do the test I receive this message:
-bash-2.05b$ mpirun -np 4 /home/asantana/amber/amber8/exe/psander -O -i -o spc_min.out -p -c spc_C.crd -r spc_minR.rst -e
spc_minE.ENE -v spc_minV.VEL -x spc_minX.emcrd -inf spc_minI.INF
It seems that there is no lamd running on the host

This indicates that the LAM/MPI runtime environment is not operating.
The LAM/MPI runtime environment is necessary for the "mpirun" command.

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 have Gromacs running in the same machine and tons tell me nothing about the
lamboot. What could be the problem???
