[petsc-users] [EXTERNAL] Re: Using multiple MPI ranks with COO interface crashes in some cases

I built petsc with:

$ ./configure PETSC_DIR=$PWD PETSC_ARCH=arch-kokkos-serial-debug --with-cc=mpicc --with-cxx=mpicxx --with-fc=0 --with-debugging=0 --prefix=$HOME/build/petsc/debug/install --with-64-bit-indices --with-shared-libraries --COPTFLAGS=-O3 --CXXOPTFLAGS=-O3 --download-kokkos --download-kokkos-kernels

$ make PETSC_DIR=$PWD PETSC_ARCH=arch-kokkos-serial-debug all

$ make PETSC_DIR=$PWD PETSC_ARCH=arch-kokkos-serial-debug install


Then I build xolotl in a separate build directory (after checking out the "feature-petsc-kokkos" branch) with:

$ cmake -DCMAKE_BUILD_TYPE=Debug -DKokkos_DIR=$HOME/build/petsc/debug/install -DPETSC_DIR=$HOME/build/petsc/debug/install <xolotl-src>

$ make -j4 SystemTester


Then, from the xolotl build directory, run (for example):

$ mpirun -n 2 ./test/system/SystemTester -t System/NE_4 -- -v

Note that this test case will use the parameter file '<xolotl-src>/benchmarks/params_system_NE_4.txt' which has the command-line arguments for petsc in its "petscArgs=..." line. If you look at '<xolotl-src>/test/system/SystemTester.cpp' all the system test cases follow the same naming convention with their corresponding parameter files under '<xolotl-src>/benchmarks'.

The failure happens with the NE_4 case (which is 2D) and the PSI_3 case (which is 1D).

Let me know if this is still unclear.

Hi, Philip,
  Can you tell me instructions to build Xolotl to reproduce the error?

In Xolotl's "feature-petsc-kokkos" branch, I have moved our code to use the COO interface for preallocating and setting values in the Jacobian matrix. I have found that with some of our test cases, using more than one MPI rank results in a crash. Way down in the preconditioner code in petsc a Mat gets computed that has "null" for the "productsymbolic" member of its "ops". It's pretty far removed from where we compute the Jacobian entries, so I haven't been able (so far) to track it back to an error in my code. I'd appreciate some help with this from someone who is more familiar with the petsc guts so we can figure out what I'm doing wrong. (I'm assuming it's a bug in Xolotl.)

Note that this is using the kokkos backend for Mat and Vec in petsc, but with a serial-only build of kokkos and kokkos-kernels. So, it's a CPU-only multiple MPI rank run.

Here's a paste of the error output showing the relevant parts of the call stack:
