It is at the subdir test/mpi of downloaded mpich <http://www.mpich.org/static/downloads/3.3.2/mpich-3.3.2.tar.gz>. It annoyed me since it is not user-friendly. It might be helpful in catching bugs at very small scale. But say if I want to test allreduce on 1024 ranks on 100 doubles, I have to hack the test suite. Anyway, the instructions are here. For the purpose of petsc, under test/mpi one can configure it with $./configure CC=mpicc CXX=mpicxx FC=mpifort --enable-strictmpi --enable-threads=funneled --enable-fortran=f77,f90 --enable-fast --disable-spawn --disable-cxx --disable-ft-tests // It is weird I disabled cxx but I had to set CXX! $make -k -j8 // -k is to keep going and ignore compilation errors, e.g., when building tests for MPICH extensions not in MPI standard, but your MPI is OpenMPI. $ // edit testlist, remove lines mpi_t, rma, f77, impls. Those are sub-dirs containing tests for MPI routines Petsc does not rely on. $ make testings or directly './runtests -tests=testlist' On a batch system, $export MPITEST_BATCHDIR=`pwd`/btest // specify a batch dir, say btest, $./runtests -batch -mpiexec=mpirun -np=1024 -tests=testlist // Use 1024 ranks if a test does no specify the number of processes. $ // It copies test binaries to the batch dir and generates a script runtests.batch there. Edit the script to fit your batch system and then submit a job and wait for its finish. $ cd btest && ../checktests --ignorebogus PS: Fande, changing an MPI fixed your problem does not necessarily mean the old MPI has bugs. It is complicated. It could be a petsc bug. You need to provide us a code to reproduce your error. It does not matter if the code is big. > Thanks > > Barry > > > On Jul 20, 2020, at 12:16 AM, Fande Kong <fdkong...@gmail.com> wrote: > > Trace could look like this: > > [640]PETSC ERROR: --------------------- Error Message > -------------------------------------------------------------- > [640]PETSC ERROR: Argument out of range > [640]PETSC ERROR: key 45226154 is greater than largest key allowed 740521 > [640]PETSC ERROR: See https://www.mcs.anl.gov/petsc/documentation/faq.html for > trouble shooting. > [640]PETSC ERROR: Petsc Release Version 3.13.3, unknown > [640]PETSC ERROR: ../../griffin-opt on a arch-moose named r6i5n18 by > wangy2 Sun Jul 19 17:14:28 2020 > [640]PETSC ERROR: Configure options --download-hypre=1 --with-debugging=no > --with-shared-libraries=1 --download-fblaslapack=1 --download-metis=1 > --download-ptscotch=1 --download-parmetis=1 --download-superlu_dist=1 > --download-mumps=1 --download-scalapack=1 --download-slepc=1 --with-mpi=1 > --with-cxx-dialect=C++11 --with-fortran-bindings=0 --with-sowing=0 > --with-64-bit-indices --download-mumps=0 > [640]PETSC ERROR: #1 PetscTableFind() line 132 in > /home/wangy2/trunk/sawtooth/griffin/moose/petsc/include/petscctable.h > [640]PETSC ERROR: #2 MatSetUpMultiply_MPIAIJ() line 33 in > /home/wangy2/trunk/sawtooth/griffin/moose/petsc/src/mat/impls/aij/mpi/mmaij.c > [640]PETSC ERROR: #3 MatAssemblyEnd_MPIAIJ() line 876 in > /home/wangy2/trunk/sawtooth/griffin/moose/petsc/src/mat/impls/aij/mpi/mpiaij.c > [640]PETSC ERROR: #4 MatAssemblyEnd() line 5347 in > /home/wangy2/trunk/sawtooth/griffin/moose/petsc/src/mat/interface/matrix.c > [640]PETSC ERROR: #5 MatPtAPNumeric_MPIAIJ_MPIXAIJ_allatonce() line 901 in > /home/wangy2/trunk/sawtooth/griffin/moose/petsc/src/mat/impls/aij/mpi/mpiptap.c > [640]PETSC ERROR: #6 MatPtAPNumeric_MPIAIJ_MPIMAIJ_allatonce() line 3180 > in /home/wangy2/trunk/sawtooth/griffin/moose/petsc/src/mat/impls/maij/maij.c > [640]PETSC ERROR: #7 MatProductNumeric_PtAP() line 704 in > /home/wangy2/trunk/sawtooth/griffin/moose/petsc/src/mat/interface/matproduct.c > [640]PETSC ERROR: #8 MatProductNumeric() line 759 in > /home/wangy2/trunk/sawtooth/griffin/moose/petsc/src/mat/interface/matproduct.c > [640]PETSC ERROR: #9 MatPtAP() line 9199 in > /home/wangy2/trunk/sawtooth/griffin/moose/petsc/src/mat/interface/matrix.c > [640]PETSC ERROR: #10 MatGalerkin() line 10236 in > /home/wangy2/trunk/sawtooth/griffin/moose/petsc/src/mat/interface/matrix.c > [640]PETSC ERROR: #11 PCSetUp_MG() line 745 in > /home/wangy2/trunk/sawtooth/griffin/moose/petsc/src/ksp/pc/impls/mg/mg.c > [640]PETSC ERROR: #12 PCSetUp_HMG() line 220 in > /home/wangy2/trunk/sawtooth/griffin/moose/petsc/src/ksp/pc/impls/hmg/hmg.c > [640]PETSC ERROR: #13 PCSetUp() line 898 in > /home/wangy2/trunk/sawtooth/griffin/moose/petsc/src/ksp/pc/interface/precon.c > [640]PETSC ERROR: #14 KSPSetUp() line 376 in > /home/wangy2/trunk/sawtooth/griffin/moose/petsc/src/ksp/ksp/interface/itfunc.c > [640]PETSC ERROR: #15 KSPSolve_Private() line 633 in > /home/wangy2/trunk/sawtooth/griffin/moose/petsc/src/ksp/ksp/interface/itfunc.c > [640]PETSC ERROR: #16 KSPSolve() line 853 in > /home/wangy2/trunk/sawtooth/griffin/moose/petsc/src/ksp/ksp/interface/itfunc.c > [640]PETSC ERROR: #17 SNESSolve_NEWTONLS() line 225 in > /home/wangy2/trunk/sawtooth/griffin/moose/petsc/src/snes/impls/ls/ls.c > [640]PETSC ERROR: #18 SNESSolve() line 4519 in > /home/wangy2/trunk/sawtooth/griffin/moose/petsc/src/snes/interface/snes.c > > On Sun, Jul 19, 2020 at 11:13 PM Fande Kong <fdkong...@gmail.com> wrote: > >> I am not entirely sure what is happening, but we encountered similar >> issues recently.
