Hi all, Your help with the following torque integration issue will be much appreciated: whenever I try to start a openmpi job on more than one node, it simply does not start up on the nodes. The torque job fails with the following:
> Fri Dec 18 22:11:07 CET 2009 > OpenMPI with PPU-GCC was loaded > -------------------------------------------------------------------------- > A daemon (pid unknown) died unexpectedly on signal 1 while attempting to > launch so we are aborting. > > There may be more information reported by the environment (see above). > > This may be because the daemon was unable to find all the needed shared > libraries on the remote node. You may set your LD_LIBRARY_PATH to have the > location of the shared libraries on the remote nodes and this will > automatically be forwarded to the remote nodes. > -------------------------------------------------------------------------- > -------------------------------------------------------------------------- > mpirun noticed that the job aborted, but has no info as to the process > that caused that situation. > -------------------------------------------------------------------------- > -------------------------------------------------------------------------- > mpirun was unable to cleanly terminate the daemons on the nodes shown > below. Additional manual cleanup may be required - please refer to > the "orte-clean" tool for assistance. > -------------------------------------------------------------------------- > node2 - daemon did not report back when launched > Fri Dec 18 22:12:47 CET 2009 I am quite confident about the compilation and installation of torque and openmpi, since it runs without error on one node: > Fri Dec 18 22:14:11 CET 2009 > OpenMPI with PPU-GCC was loaded > Process 1 on node1 out of 2 > Process 0 on node1 out of 2 > Fri Dec 18 22:14:12 CET 2009 The called programm is a simple helloworld which runs without errors started manually on the nodes; therefore it also runs without errors using a hostfile to daemonize on more than one node. I already tried to compile openmpi with default prefix: > $ ./configure CC=ppu-gcc CPP=ppu-cpp CXX=ppu-c++ CFLAGS=-m32 > CXXFLAGS=-m32 FC=ppu-gfortran43 FCFLAGS=-m32 FFLAGS=-m32 > CCASFLAGS=-m32 LD=ppu32-ld LDFLAGS=-m32 > --prefix=/shared/openmpi_gcc_ppc --with-platform=optimized > --disable-mpi-profile --with-tm=/usr/local/ --with-wrapper-cflags=-m32 > --with-wrapper-ldflags=-m32 --with-wrapper-fflags=-m32 > --with-wrapper-fcflags=-m32 --enable-mpirun-prefix-by-default Also the called helloworld is compiled with and without -rpath, so I just wanted to be sure regarding any linked library issue. Now, the interesting fact is the following: I compiled on one node a kernel with CONFIG_BSD_PROCESS_ACCT_V3 to monitor the startup of the pbs, mpi and helloworld daemons. And as already mentioned at the beginning, therefore I assumed that the mpi startup within torque is not working for me. Please request any further logs or so you want to review, I did not wanted to get the mail to large at first. Any ideas? Greetings, Johann
