Hello, I hope, I am framing the question currently. Are only distributed arrays (DMDA) of -vec_type and -mat_type only supported by CUDA?
I am reading the petsc user manual in section 2.4 distributed arrays are introduced but at the start of chapter two there are other vector and matrix types as well. I wonder if these types (I don’t how they are referred by) are also CUDA supported? Can you please point me to some tutorial examples in KSP and SNES that can run on gpus? At the moment I am testing KSP/ex45.c with different preconditioners on cpus and gpus. I tried to run KSP/ex2.c with -vec_type cuda and -mat_type aijcuda noticed there was no gpu flops recorded in my log file. Many thanks, Karthik.
