Hi Stefano,
I have just noticed we have different occurrences of the
valid_GPU_matrix flag in src/mat/interface and src/mat/utils
I think that how they are used now is wrong, as they assume that all
those operations can only be executed on the CPU, irrespective of the
specific type.
Is there any plan to fix this? If not, I can take care of it, I am
currently writing a dense matrix for CUDA here
https://bitbucket.org/petsc/petsc/branch/stefano_zampini/cuda
there is going to be a major reorganization of the GPU code over the
next few weeks, cf.
https://bitbucket.org/petsc/petsc/issues/322/working-group-gpus
This, however, is pretty much orthogonal to your development of a dense
matrix type. Once your branch is ready, it can be rather easily adopted.
As for the valid_GPU_matrix flag: This will be fixed alongside the the
GPU reorganization. However, it might take 2-3 weeks until I finally get
to that part. I guess you will need it sooner?
Best regards,
Karli
