Hello,
I have installed OpenFOAM-1.4 on a linux machine running on Redhat enterprise 4. I was able to complete the installation, and I'm now trying to setup the mpi capability. I generated keys with ssh-keygen and I can connect to a second computer without passwords. The error I get after launching lamboot -v <myfile> is: LAM 7.1.2 - Indiana University n-1<6232> ssi:boot:base:linear: booting n0 (128.61.185.163) ----------------------------------------------------------------------------- The lamboot agent failed to read a message over a socket from the newly-booted process. This should not happen (especially since TCP is a guaranteed protocol). *** PLEASE READ THIS ENTIRE MESSAGE, FOLLOW ITS SUGGESTIONS, AND *** CONSULT THE "BOOTING LAM" SECTION OF THE LAM/MPI FAQ *** (http://www.lam-mpi.org/faq/) BEFORE POSTING TO THE LAM/MPI USER'S *** MAILING LIST. You should probably check the following: - Network connectivity: Ensure that messages can be passed reliably over TCP using random ports. - Environment / PATH settings: Ensure that you are running the same version of LAM/MPI on all nodes. Sometimes premature disconnects (and therefore this error message) may be caused if mismatched versions of LAM are used on different nodes. - Node health: Ensure that the host where the newly-booted process was launched is healthy and still available on the network. ----------------------------------------------------------------------------- n-1<6232> ssi:boot:base:linear: aborted! lamboot did NOT complete successfully Do I need to install the lam verision that comes with OpenFOAM on all the machines that I will be running via OpenFOAM? Thank you in advance |

If I'm not wrong, lamboot try to check if it can open a ssh connection with the other specified machines.
Basicly, it execute a command through ssh and check the standard error. Execute "lamboot -v" to have some more verbose output. In my case, the error was due to the X11 forwarding. I remeber I resolved it by using "ssh -x" as remote connection client. Check in the lamport documentation how to do this... I really don't remember what I did, and I'm not using that system anymore... Hope this can be a starting point... Francesco |
