Can work on Cuda-LU, will work with BaSpaCho (as Jt x J is/will be computed externally), no chance with Cholmod as it’s computing Jt x J internally (adding only possibly one constant to the diagonal). To make it work with Cholmod need to implement externally the operation Jt x J (but I think BaSpaCho will prove to superseed Cholmod also as CPU-only solver).
@maurimo I forgot what the status of this. Can you remind me which of our sparse solvers (if any) currently support this?
