Greetings, I can't get OpenMPI programs to run in a chroot environment on Debian. If I run the program, it dies as follows:
# ./ex0 [workhorse:23752] [0,0,0] ORTE_ERROR_LOG: Error in file runtime/orte_init_stage1.c at line 312 -------------------------------------------------------------------------- It looks like orte_init failed for some reason; your parallel process is likely to abort. There are many reasons that a parallel process can fail during orte_init; some of which are due to configuration or environment problems. This failure appears to be an internal failure; here's some additional information (which may only be relevant to an Open MPI developer): orte_pls_base_select failed --> Returned value -1 instead of ORTE_SUCCESS -------------------------------------------------------------------------- -------------------------------------------------------------------------- It looks like MPI_INIT failed for some reason; your parallel process is likely to abort. There are many reasons that a parallel process can fail during MPI_INIT; some of which are due to configuration or environment problems. This failure appears to be an internal failure; here's some additional information (which may only be relevant to an Open MPI developer): ompi_mpi_init: orte_init_stage1 failed --> Returned "Error" (-1) instead of "Success" (0) -------------------------------------------------------------------------- *** An error occurred in MPI_Init *** before MPI was initialized *** MPI_ERRORS_ARE_FATAL (goodbye) [workhorse:23752] Abort before MPI_INIT completed successfully; not able to guarantee that all other processes were killed! If I run it with mpirun, it does slightly differently: $ mpirun -np 1 ./ex0 [workhorse:23457] [0,0,0] ORTE_ERROR_LOG: Error in file runtime/orte_init_stage1.c at line 312 -------------------------------------------------------------------------- It looks like orte_init failed for some reason; your parallel process is likely to abort.

The error occured while attempting to orte_init(). Returned value -1 instead of ORTE_SUCCESS. -------------------------------------------------------------------------- The above output is identical whether I use -v, --verbose, or -mca btl self. Also, I can't start orted in the chroot: it detaches without leaving a running process behind. In a normal non-chroot environment it works fine. Is it possible to run OpenMPI programs in a chroot environment? I understand that it might not be possible to use a cluster with chroots on each node, but how about running a single instance of an MPI program? Or on a multi-CPU (multi-core etc.) shared memory machine?
