[OMPI users] Xgrid and Kerberos

What's the proper setup for using kerberos-single-sign-on with OpenMPI? For now I've added the two environment variable XGRID_CONTROLLER_HOSTNAME and XGRID_CONTROLLER_PASSWORD to submit jobs to the grid. Yours, Frank

[OMPI users] OS X, OpenMPI 1.1: An error occurred in MPI_Allreduce on communicator MPI_COMM_WORLD

Hi All, when the nodes belong to different subnets the following error messages pop up: [powerbook.2-net:20826] *** An error occurred in MPI_Allreduce [powerbook.2-net:20826] *** on communicator MPI_COMM_WORLD [powerbook.2-net:20826] *** MPI_ERR_INTERN: internal error [powerbook.2-net:20826] **

@ Terry (and All)! Enclose you'll find a (minor) bugfix with respect to the BUS_ADRALN I've reported recently when submitting jobs to the XGrid with OpenMPI 1.1. The BUS_ADRALN error on SPARC systems might be caused by a similar code segment. For the "bugfix" see line 55ff of the attached code

ack would help me try and determine if this is an OpenMPI issue or possibly some type of platform problem. There is another thread with Eric Thibodeau that I am unsure if it is the same issue as either of our situation. --td > >Message: 3 >Date: Wed, 28 Jun 2006 14:30:12 +0200 &

Hi Eric (and all), don't know if this really messes things up, but you have set up lam-mpi in your path-variables, too: [enterprise:24786] pls:rsh: reset LD_LIBRARY_PATH: /export/lca/home/lca0/etudiants/ac38820/openmpi_sun4u/lib:/export/lca/appl/Forte/SUNWspro/WS6U2/lib:/usr/local/lib:*/usr/l

Hi Terry, unfortunately I haven't got a stack trace. OS: Mac OS X 10.4.7 Server on the Xgrid-server and Mac OS X 10.4.7 Client on every node (G4 and G5). For testing-purposes I've installed OpenMPI 1.1 on a Dual-G4-node and on a Dual-G5-node with my Xgrid consisting of only either the Dual-G4
