Hello again,
Ralph Castain wrote:Yes, that would indeed break things. The 1.5 series isn't correctly checking connections across multiple interfaces until it finds one that works - it just uses the first one it sees. :-(Yahhh!! This behaviour - catch a random interface and hang forever if something is wrong with it - is somewhat less than perfect.From my perspective - the users one - OpenMPI should try to use eitcher *all* available networks (as 1.4 it does...), starting with the high performance ones, or *only* those interfaces on which the hostnames from the hostfile are bound to.It is indeed supposed to do the former - as I implied, this is a bug in the 1.5 series.
Thanks for clarification. I was not sure about this is a bug or a feature :-)
Also, there should be timeouts (if you cannot connect to a node within a minute you probably will never ever be connected...)We have debated about this for some time - there is a timeout mca param one can set, but we'll consider again making it default.If some connection runs into a timeout a warning would be great (and a hint to take off the interface by oob_tcp_if_exclude, btl_tcp_if_exclude). Should it not? Maybe you can file it as a "call for enhancement"...Probably the right approach at this time.
Ahhh.. sorry, did not understand what you mean.Did you filed it, or someone else, or should I do it in some way? Or should not?
But then I ran into yet another one issue. In http://www.open-mpi.org/faq/?category=tuning#setting-mca-params the way to define MCA parameters over environment variables is described. I tried it: $ export OMPI_MCA_oob_tcp_if_include=ib0 $ export OMPI_MCA_btl_tcp_if_include=ib0 I checked it: $ ompi_info --param all all | grep oob_tcp_if_include MCA oob: parameter "oob_tcp_if_include" (current value: <ib0>, data source: environment or cmdline) $ ompi_info --param all all | grep btl_tcp_if_include MCA btl: parameter "btl_tcp_if_include" (current value: <ib0>, data source: environment or cmdline) But then I get again the hang-up issue! ==> seem, mpiexec does not understand these environment variables! and only get the command line options. This should not be so?No, that isn't what is happening. The problem lies in the behavior of rsh/ssh. This environment does not forward environmental variables. Because of limits on cmd line length, we don't automatically forward MCA params from the environment, but only from the cmd line. It is an annoying limitation, but one outside our control.
We know about "ssh does not forward environmental variables." But in this case, are these parameters not the parameters of mpiexec itself, too?
The crucial thing is, that setting of the parameters works over the command line but *does not work* over the envvar way (as in http://www.open-mpi.org/faq/?category=tuning#setting-mca-params described). This looks like a bug for me!
Put those envars in the default mca param file and the problem will be resolved.
You mean e.g. $prefix/etc/openmpi-mca-params.conf as described in 4. of http://www.open-mpi.org/faq/?category=tuning#setting-mca-params
Well, this is possible, but not flexible enough for us (because there are some machines which only can run if the parameters are *not* set - on those the ssh goes just over these eth0 devices).
By now we use the command line parameters and hope the envvar way will work sometimes.
(I also tried to advise to provide the envvars by -x OMPI_MCA_oob_tcp_if_include -x OMPI_MCA_btl_tcp_if_include - nothing changed.I'm surprised by that - they should be picked up and forwarded. Could be a bug
Well, I also mean this is a bug, but as said not on providing the values of envvars but on detecting of these parameters at all. Or maybe on both.
Well, they are OMPI_ variables and should be provided in any case).No, they aren't - they are not treated differently than any other envar.
[after performing some RTFM...]at least the man page of mpiexec says, the OMPI_ environment variables are always provided and thus treated *differently* than other envvars:
$ man mpiexec .... Exported Environment VariablesAll environment variables that are named in the form OMPI_* will automatically be exported to new processes on the local and remote nodes.
So, tells the man page lies, or this is an removed feature, or something else?
Best wishes, Paul Kapinos
Specifying both include and exclude should generate an error as those are mutually exclusive options - I think this was also missed in early 1.5 releases and was recently patched.

The good: we believe to find out *why* it hangs The bad: it seem for me, this is a bug or at least undocumented feature of Open MPI /1.5.x. In detail: As said, we see mystery hang-ups if starting on some nodes using some permutation of hostnames. Usually removing "some bad" nodes helps, sometimes a permutation of node names in the hostfile is enough(!). The behaviour is reproducible. The machines have at least 2 networks: *eth0* is used for installation, monitoring, ... - this ethernet is very slim *ib0* - is the "IP over IB" interface and is used for everything: the file systems, ssh and so on. The hostnames are bound to the ib0 network; our idea was not to use eth0 for MPI at all. all machines are available from any over ib0 (are in one network). But on eth0 there are at least two different networks; especially the computer linuxbsc025 is in different network than the others and is not reachable from other nodes over eth0! (but reachable over ib0. The name used in the hostfile is resolved to the IP of ib0 ). So I believe that Open MPI /1.5.x tries to communicate over eth0 and cannot do it, and hangs. The /1.4.3 does not hang, so this issue is 1.5.x-specific (seen in 1.5.3 and 1.5.4). A bug? I also tried to disable the eth0 completely: $ mpiexec -mca btl_tcp_if_exclude eth0,lo -mca btl_tcp_if_include ib0 ...I believe if you give "-mca btl_tcp_if_include ib0" you do not need to specify the exclude parameter....but this does not help. All right, the above command should disable the usage of eth0 for MPI communication itself, but it hangs just before the MPI is started, isn't it? (because one process lacks, the MPI_INIT cannot be passed)By "just before the MPI is started" do you mean while orte is launching the processes. I wonder if you need to specify "-mca oob_tcp_if_include ib0" also but I think that may depend on which oob you are using.Now a question: is there a way to forbid the mpiexec to use some interfaces at all? Best wishes, Paul Kapinos P.S. Of course we know about the good idea to bring all nodes into the same net on eth0, but at this point it is impossible due of technical reason[s]... P.S.2 I'm not sure that the issue is really rooted in the above mentioned misconfiguration of eth0, but I have no better idea at this point...The map seem to be correctly build, also the output if the daemons seem to be the same (see helloworld.txt)Unfortunately, it appears that OMPI was not built with --enable-debug as there is no debug info in the output. Without a debug installation of OMPI, the ability to determine the problem is pretty limited.well, this will be the next option we will activate. We also have another issue here, on (not) using uDAPL..You should also try putting that long list of nodes in a hostfile - see if that makes a difference. It will process the nodes thru a different code path, so if there is some problem in --host, this will tell us.No, with the host file instead of host list on command line the behaviour is the same. But, I just found out that the 1.4.3 does *not* hang on this constellation. The next thing I will try will be the installation of 1.5.4 :o) Best, Paul P.S. started: $ /opt/MPI/openmpi-1.5.3/linux/intel/bin/mpiexec --hostfile hostfile-mini -mca odls_base_verbose 5 --leave-session-attached --display-map helloworld 2>&1 | tee helloworld.txtOn Nov 21, 2011, at 9:33 AM, Paul Kapinos wrote:Hello Open MPI volks, We use OpenMPI 1.5.3 on our pretty new 1800+ nodes InfiniBand cluster, and we have some strange hangups if starting OpenMPI processes. The nodes are named linuxbsc001,linuxbsc002,... (with some lacuna due of offline nodes). Each node is accessible from each other over SSH (without password), also MPI programs between any two nodes are checked to run. So long, I tried to start some bigger number of processes, one process per node: $ mpiexec -np NN --host linuxbsc001,linuxbsc002,... MPI_FastTest.exe Now the problem: there are some constellations of names in the host list on which mpiexec reproducible hangs forever; and more surprising: other *permutation* of the *same* node names may run without any errors! Example: the command in laueft.txt runs OK, the command in haengt.txt hangs. Note: the only difference is that the node linuxbsc025 is put on the end of the host list. Amazed, too? Looking on the particular nodes during the above mpiexec hangs, we found the orted daemons started on *each* node and the binary on all but one node (orted.txt, MPI_FastTest.txt). Again amazing that the node with no user process started (leading to hangup in MPI_Init of all processes and thus to hangup, I believe) was always the same, linuxbsc005, which is NOT the permuted item linuxbsc025... This behaviour is reproducible. The hang-on only occure if the started application is a MPI application ("hostname" does not hang). Any Idea what is gonna on?
