Dear folks, I would appreciate your help on the following:
I'm running a parallel CFD code on the Army Research Lab's MJM Linux cluster, which uses Open-MPI. I've run the same code on other Linux clusters that use MPICH2 and had never run into this problem. I'm quite convinced that the bottleneck for my code is this data transposition routine, although I have not done any rigorous profiling to check on it. This is where 90% of the parallel communication takes place. I'm running a CFD code that uses a 3-D rectangular domain which is partitioned across processors in such a way that each processor stores vertical slabs that are contiguous in the x-direction but shared across processors in the y-dir. . When a 2-D Fast Fourier Transform (FFT) needs to be done, data is transposed such that the vertical slabs are now contiguous in the y-dir. in each processor. The code would normally be run for about 10,000 timesteps. In the specific case which blocks, the job crashes after ~200 timesteps and at each timestep a large number of 2-D FFTs are performed. For a domain with resolution of Nx * Ny * Nz points and P processors, during one FFT, each processor performs P Sends and P Receives of a message of size (Nx*Ny*Nz)/P, i.e. there are a total of 2*P^2 such Sends/Receives. I've focused on a case using P=32 procs with Nx=256, Ny=128, Nz=175. You can see that each FFT involves 2048 communications. I totally rewrote my data transposition routine to no longer use specific blocking/non- blocking Sends/Receives but to use MPI_ALLTOALL which I would hope is optimized for the specific MPI Implementation to do data transpositions. Unfortunately, my code still crashes with time-out problems like before. This happens for P=4, 8, 16 & 32 processors. The same MPI_ALLTOALL code worked fine on a smaller cluster here. Note that in the future I would like to work with resolutions of (Nx,Ny,Nz)=(512,256,533) and P=128 or 256 procs. which will involve an order of magnitude more communication. Note that I ran the job by submitting it to an LSF queue system. I've attached the script file used for that. I basically enter bsub -x < script_openmpi at the command line. When I communicated with a consultant at ARL, he recommended I use 3 specific script files which I've attached. I believe these enable control over some of the MCA parameters. I've experimented with values of btl_mvapi_ib_timeout = 14, 18, 20, 24 and 30 and I still have this problem. I am still in contact with this consultant but thought it would be good to contact you folks directly. Note: a) echo $PATH returns: /opt/mpi/x86_64/pgi/6.2/openmpi-1.2/bin: /opt/compiler/pgi/linux86-64/6.2/bin:/usr/lsf/6.2/linux2.6-glibc2.3- ia32e/bin:/usr/lsf/6.2/linux2.6-glibc2.3- ia32e/etc:/usr/cta/modules/3.1.6/bin: /usr/local/bin:/usr/bin:/usr/X11R6/bin:/bin:/usr/games:/opt/gnome/bin: .:/usr/lib/java/bin:/opt/gm/bin:/opt/mx/bin:/opt/PST/bin b) echo $LD_LIBRARY_PATH returns: /opt/mpi/x86_64/pgi/6.2/openmpi-1.2/lib: /opt/compiler/pgi/linux86-64/6.2/lib: /opt/compiler/pgi/linux86-64/6.2/libso:/usr/lsf/6.2/linux2.6-glibc2.3- ia32e/lib I've attached the following files: 1) Gzipped versions of the .out & .err files of the failed job. 2) ompi_info.log: The output of ompi_info -all 3) mpirun, mpirun.lsf, openmpi_wrapper: the three script files provided to me by the ARL consultant. I store these in my home directory and experimented with the MCA parameter btl_mvapi_ib_timeout in mpirun. 4) The script file script_openmpi that I use to submit the job. I am unable to provide you with the config.log file as I cannot find it in the top level Open MPI directory. I am also unable to provide you with details on the specific cluster that I'm running in terms of the network. I know they use Infiniband and some more detail may be found on: http://www.arl.hpc.mil/Systems/mjm.html Some other info: a) uname -a returns: Linux l1 2.6.5-7.308-smp.arl-msrc #2 SMP Thu Jan 10 09:18:41 EST 2008 x86_64 x86_64 x86_64 GNU/Linux b) ulimit -l returns: unlimited I cannot see a pattern as to which nodes are bad and which are good ... Note that I found in the mail archives that someone had a similar problem in transposing a matrix with 16 million elements. The only answer I found in the thread was to increase the value of btl_mvapi_ib_timeout to 14 or 16, something I've done already. I'm hoping that there must be a way out of this problem. I need to get my code running as I'm under pressure to produce results for a grant that's paying me. If you have any feedback I would be hugely grateful. Sincerely, Peter Diamessis Cornell University
