Subject: [OMPI users] some mpi processes "disappear" on a cluster of servers
From: Andrea Negri (negri.andre_at_[hidden])
Date: 2012-08-31 19:15:17


Hi, I have been in trouble for a year.

I run a pure MPI (no openMP) Fortran fluid dynamical code on a cluster
of server, and I obtain a strange behaviour by running the code on
multiple nodes.
The cluster is formed by 16 pc (1 pc is a node) with a dual core processor.
Basically, I'm able to run the code from the login node with the command:
mpirun --mca btl_base_verbose 100 --mca backtrace_base_verbose 100
--mca memory_base_verbose 100 --mca sysinfo_base_verbose 100 -nolocal
-hostfile ./host_file -n 10 ./zeusmp2.x >> zmp_errors 2>&1
by selecting one process per core (i.e. in this case I use 5 nodes)

The code starts, and it runs correctely for some time.
After that, an entire node (sometimes two) "disappears" and it cannot
be reached with the ssh command, which returns: No route to host.
Sometimes the node is still reachable, but the two processes that was
running on the node are disappears.
In addition, on the other nodes, the others processes are still running.

If I have a look on the output and error file of mpirun, the following
error is present: [btl_tcp_frag.c:215:mca_btl_tcp_frag_recv]
mca_btl_tcp_frag_recv: readv failed: No route to host (113)

PS: I'm not the admin of the cluster, I've installed the gcc and
openmpi on my own because the complier aviable on that machine are 8
years old.

I post here some information, if you want other info, you have only to
tell me which command I have to type on the bash and I will
immediately reply.

complier: gcc 4.7 (which was also used to compile openmpi)
openmpi version: 1.6

output of "ompi_info --all" from the node where I launch mpirun (which
is also the login node of the cluster)

                          Specifies where the default error output

                          Whether you want MPI API parameters checked

                 MCA mpi: parameter "mpi_show_mca_params" (current

                          source: default value)
                          Whether to show all MCA parameter values
during MPI_INIT or not

debug purposes).
                          Accepted values are all, default, file, api,

                          comma delimited combination of them
                 MCA mpi: parameter "mpi_show_mca_params_file"
(current value: <none>,
                          data source: default value)
                          If mpi_show_mca_params is true, setting this
string to a valid
                          filename tells Open MPI to dump all the MCA
parameter values
                          into a file suitable for reading via the

                 MCA mpi: parameter "mpi_keep_peer_hostnames" (current
value: <1>, data
                          source: default value)
                          If nonzero, save the string hostnames of all
MPI peer processes
                          (mostly for error / debugging output
messages). This can add
                          quite a bit of memory usage to each MPI process.
                 MCA mpi: parameter "mpi_abort_delay" (current value:
<0>, data source:
                          default value)
                          If nonzero, print out an identifying message

                          invoked (hostname, PID of the process that
called MPI_ABORT)
                          and delay for that many seconds before
exiting (a negative
                          delay value means to never abort). This
allows attaching of a
                          debugger before quitting the job.
                 MCA mpi: parameter "mpi_abort_print_stack" (current
value: <0>, data
                          source: default value)

                 MCA mpi: parameter "mpi_preconnect_mpi" (current

                          source: default value, synonyms: mpi_preconnect_all)
                          Whether to force MPI processes to fully
wire-up the MPI
                          connections between MPI processes during
MPI_INIT (vs. making
                          connections lazily -- upon the first MPI
traffic between each
                          process peer pair)
                 MCA mpi: parameter "mpi_preconnect_all" (current
value: <0>, data
                          source: default value, deprecated, synonym of:

allow the job to
                          continue (possibly with degraded
performance). A value of
                          "error" means that Open MPI will abort the
job if this happens.
