Yikes - that's not a good error. :-(
We don't regularly build / test on AIX, so I don't have much
immediate guidance for you. My best suggestion at this point would
be to try the latest 1.2 beta or nightly snapshot. We did an update
of the event engine (the portion of the code that you're seeing the
error issue from) that *may* alleviate the problem...? (I have no
idea, actually -- I'm just kinda hoping that the new version of the
event engine will fix your problem :-\ )

Dear All
I am trying to get openmpi-1.1.2 to work on AIX 5.3 / power5.
:: Compilation seems to have worked with the following sequence:
====================================================================
setenv OBJECT_MODE 64
setenv CC xlc
setenv CXX xlC
setenv F77 xlf
setenv FC xlf90
setenv CFLAGS "-qthreaded -O3 -qmaxmem=-1 -qarch=pwr5x -qtune=pwr5 -

:: After the compilation I ran make check and all 11 tests passed
successfully.
:: Now I'm trying to run the following command just for test:
# mpirun -hostfile /gpfs/MICHAEL/MPI_hostfiles/mpinodes_b41-
b44_1.asc -np 2 /usr/bin/hostname
- The file /gpfs/MICHAEL/MPI_hostfiles/mpinodes_b41-b44_1.asc
contains 4 hosts:
r1blade041 slots=1
r1blade042 slots=1
r1blade043 slots=1
r1blade044 slots=1
- The mpirun command eventually hangs with the following message:
[r1blade041:418014] poll failed with errno=25
[r1blade041:418014] opal_event_loop: ompi_evesel->dispatch()
failed.
- In this state mpirun cannot be killed by hitting <ctrl-c> only a
kill -9 will do the trick.
- While the mpirun still hangs I can see that the "orted" has been
launched on both requested hosts.
:: I turned on all debug options in openmpi-mca-params.conf. The
output for the same call of mpirun is in the file mpirun-debug.txt.gz.
<mpirun-debug.txt.gz>
:: As sugested in the mailinglis rules I include config.log
(config.log.gz) and the output of ompi_info (ompi_info.txt.gz).
<config.log.gz>
<ompi_info.txt.gz>
:: As I am completely new to openmpi (I have some experience with
lam) I am lost at this stage. I would really appreciate if someone
could give me some hints as to what is going wrong and where I
could get more info.
Best regards,
Michael Marti.
