[petsc-users] Ghost vector with MPIKOKKOS under DMSwarm

[MIGUEL MOLINOS PEREZ]

Dear all,

I have a question about using DMSwarm data with Kokkos-enabled vectors.

My particle data (including ghost particles) are stored in a DMSwarm and for solver purposes I generate PETSc vectors using VecCreateGhostWithArray. I would like to use VecMPIKOKKOS for MPI+GPU computations. Am I correct that DMSwarm field memory cannot be directly wrapped into a VecMPIKOKKOS using VecCreateGhostWithArray or VecPlaceArray? Any idea on how to proceed?

Thanks in advance.

Best,

Miguel
