Hi,<br>
<br>
I have used some of PETSc's linear solvers in the past, and was<br>
wondering is there any high level documentation on gpu support in<br>
PETSc? I couldn't find anything in the online pdf. I can see in the<br>
code some level of support for cuda vec/matrix and use of the cusp<br>
library etc. Things I'm wondering about include...<br>
