[OMPI users] Help: orted: command not found.
Hi, I run some programs by using OpenMPI 1.3.3 and when I execute the command I encountered such following error messages. sh: orted: command not found -- A daemon (pid 6797) died unexpectedly with status 127 while attempting to launch so we are aborting. There may be more information reported by the environment (see above). This may be because the daemon was unable to find all the needed shared libraries on the remote node. You may set your LD_LIBRARY_PATH to have the location of the shared libraries on the remote nodes and this will automatically be forwarded to the remote nodes. -- -- mpirun noticed that the job aborted, but has no info as to the process that caused that situation. -- mpirun: clean termination accomplished So could anyone tell me how to fix that problem? Thanks. Amy

Hi, a similar question was recently discussed on the mailing list: http://www.open-mpi.org/community/lists/users/2009/08/10458.php George Markomanolis wrote: Dear all, I am trying to figure out the algorithms that are used for some collective communications (allreduce, bcast, alltoall).

[OMPI users] question about algorithms for collective communication
Dear all, I am trying to figure out the algorithms that are used for some collective communications (allreduce, bcast, alltoall). Is there any document to explain which algorithms are used? For example I would like to know exactly how the command allreduce is analyzed to send and receive.
