Your PC is likely running a Linux distribution that has LAM installed by default, and "mpirun" is in your path ahead of mpich's mpirun. You can confirm this with `which mpirun`.
Try /mirror/mpich-1.2.7p1/bin/mpirun -np 1 cpi instead. Or make sure that /mirror/mpich-1.2.7p1/bin is at the front of your path. Don On Fri, 4 Dec 2009, christian suhendra wrote:
hello guys... im using mpich-1.2.7p1 installed on my PC but when i run mpirun i've got this error : suhendr...@cluster2:/mirror/mpich-1.2.7p1/examples$ mpirun -np 1 cpi ----------------------------------------------------------------------------- It seems that there is no lamd running on the host cluster2. 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. ----------------------------------------------------------------------------- did my mpich switch to LAM/MPI?? so what should i do?? regards christian
