Re: [OMPI users] orted: command not found
I had configured the hostfile located at ~prefix/etc/openmpi-default-hostfile. I copied the file to bernie-3, and it worked... Now, at the cluster I was working at the Universidad de Los Andes (Venezuela) -I decided to install mpi on three machines I was able to put together as a personal proyect- all I had to do was to compile and run my applications, that is, I never copied any file to any other machine... now, I had to. I'm sorry if it was obvious and made you guys loose some time, but why on a cluster I didn't have to copy any files, and now I must do so? Thanks for you patiance! Jose

I installed openmpi 1.1.2 on two 686 boxes runing ubuntu 6.10.
Followed the instructions given in the FAQ. Nevertheless, I get the
following message:
[bernie-1:05053] ERROR: A daemon on node 192.168.1.113 failed to start as
expected.
[bernie-1:05053] ERROR: There may be more information available from
[bernie-1:05053] ERROR: the remote shell (see above).
[bernie-1:05053] ERROR: The daemon exited unexpectedly with status 127.
now, I've been browsing the web, including the mailing lists, and it
appears that the error should be that I have not declared the variables
export PATH="/usr/local/openmpi/bin:${PATH}"
export LD_LIBRARY_PATH="/usr/local/openmpi/lib:${LD_LIBRARY_PATH}"
at the node, wich I have. I have even created all the posible folders
proposed at the FAQ for remote loggins, although I'm using bash.
If I do a ssh user@remote_node, I can connect without being asked for a
password, and if I type mpif90, I get: "gfortran: no input files", wich
should mean that indeed the PATH and LD_LIBRARY_PATH are being updated on
the remote logging.
But, if I do:
bash$ mpirun --prefix /usr/local/openmpi -np 2 prueba.bin
the result is:
--
Failed to find the following executable:
Host: bernie-3
Executable: prueba.bin
Cannot continue.
--
mpirun noticed that job rank 0 with PID 0 on node "192.168.1.113" exited
on signal 4.
I've been looking around, but have not been able to find what does the
signal 4 means.
Just in case, I was running an example program wich runs fine at my
university cluster. Nevertheless, decided to run an even simpler one, wich
I include, for it may be that the error is there (I definitly hope
not!...)
program test
use mpi
implicit none
integer :: myid,sizze,ierr
call MPI_INIT(ierr)
call MPI_COMM_SIZE(MPI_COMM_WORLD,sizze,ierr)
call MPI_COMM_RANK(MPI_COMM_WORLD,myid,ierr)
print *,"I'm using ",sizze," processors"
print *,"of wich I'm the number ",myid
call MPI_FINALIZE(ierr)
end program test
This is the first time I have installed -and use- any parallel programing
program or library, and I'm doing it as a personal proyect for a graduate
curse, so any help will be greatly appreciated!
Best regards
Jose Colmenares
