[petsc-dev] [SLEPc - GPU] Problems running SLEPc on GPUs

Hi everybody,

I have recently being trying to run SLEPc on GPUs, but I am experiencing some trouble.
I think I correctly installed PETSc to run on GPUs, as I can actually see an execution time difference in PETSc programs when run with or without -vec_type cusp -mat_type aijcusp.
When I try to do the same with SLEPc, I get the following error [running hands-on exercise 2]
[0]PETSC ERROR: No support for this operation for this object type
[0]PETSC ERROR: Cannot create a BVSVEC from a non-standard template vector

>From the documentation I understood this BVSVEC is a base SLEPc type, so I am not sure how to interpret this [wouldn't know what to touch at high-level].
Can anyone please point me to some examples/documentation on this?

Thanks in advance

Massimiliano Leoni
