Dear members,
I have problem in lamboot. I also found this topic on the FAQs page. I have tried possible solutions but still the error. When booting lam-mpi on openSUSE 10.3, I got the following error messages:
zayar_at_HPC-3:~>lamboot -v bhost
LAM 7.1.4/MPI 2 C++/ROMIO - Indiana University
n-1<25538> ssi:boot:base:linear: booting n0 (HPC-3)
n-1<25538> ssi:boot:base:linear: booting n1 (HPC-2)
-----------------------------------------------------------------------------
The lamboot agent timed out while waiting for the newly-booted process
to call back and indicated that it had successfully booted.
*** 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.
As far as LAM could tell, the remote process started properly, but
then never called back. Possible reasons that this may happen:
- There are network filters between the lamboot agent host and
the remote host such that communication on random TCP ports
is blocked
- Network routing from the remote host to the local host isn't
properly configured (this is uncommon)
You can check these things by watching the output from "lamboot -d".
1. On the command line for hboot, there are two important parameters:
one is the IP address of where the lamboot agent was invoked, the
other is the port number that the lamboot agent is expecting the
newly-booted process to call back on (this will be a random
integer).
2. Manually login to the remote machine and try to telnet to the port
indicated on the hboot command line. For example,
telnet <ipnumber> <portnumber>
If all goes well, you should get a "Connection refused" error. If
you get any other kind of error, it could indicate either of the
two conditions above. Consult with your system/network
administrator.
