Consolidate PETSc stream types
The various PetscXXXRegisterFinalize() should execute finalizers in reverse order of registration
Consolidate various C++ pool allocators into single implementation
Sys: Updated tests
Add explicit test for PetscDevice command line init sequence controls
improve coverage of various PetscDevice and PetscDeviceContext corner cases
Add a fast-path when repeatedly marking the same object with conflicting access modes to avoid excessive event churn
PetscDeviceAllocate() takes an alignment parameter as well
Rework PetscDeviceContext backends and supporting code:- Add PETSC_DEVICE_HOST- Add PetscDeviceAllocate()- Add PetscDeviceMalloc()- Add PetscDeviceDeallocate()- Add PetscDeviceFree()- Add Petsc
Rework PetscDeviceContext backends and supporting code:- Add PETSC_DEVICE_HOST- Add PetscDeviceAllocate()- Add PetscDeviceMalloc()- Add PetscDeviceDeallocate()- Add PetscDeviceFree()- Add PetscDeviceMemcopy()- Add PetscDeviceArraycopy()- Split petscdevice.h into petscdevice_cuda.h and petscdevice_hip.h- Add petscdevice_cupm.h- Extend cupm::Interface and cupm::BlasInterface classes- Add more C++ utility wrappers
