I’ve also printed out the head struct in the debugger, and it looks like this:
(lldb) print (TRSPACE)*head(TRSPACE) $7 = {

rsize = 16

Hmm, looks like your build may be funny? It is not in debug mode

Hi PETSc-developers,
In our application we call KSP_Solve as part of a step to propagate a beam
through a lattice. I am observing a crash within KSP_Solve for an application
only after the 43rd call to KSP_Solve when building the application and PETSc
in debug mode, full logs for which are

Hi PETSc-developers,
Is it possible to use VecSetValues with distributed-memory CUDA & Kokkos
vectors from the device, i.e. can I call VecSetValues with GPU memory pointers
and expect PETSc to figure out how to stash on the device it until I call
VecAssemblyBegin (at which point PETSc could

Hi PETSc-developers,
Could the linear solver table (at
https://petsc.org/main/overview/linear_solve_table/) be updated with
information regarding direct solvers that work on mpiaijkokkos/kokkos (or
mpiaijcusparse/cuda) matrix/vector types?
The use case for this solver would be to repeatedly
