Is there a GPU version of FEniCS available?

Question

Hello,

I've read a paper about changing dolfin to PETScCusp[0], and on the change log found on bitbucket[1], there's the change on line 400

• "Add new linear algebra backend "PETScCusp" for GPU-accelerated
  linear algebra"

In my researchs, to use this i should set

• " parameters["linear_algebra_backend"]="PETScCusp" "

but doing so gives the following error:

• Reason: Illegal value for parameter "linear_algebra_backend". Allowed values are: [Eigen, PETSc].
• Where: This error was encountered inside Parameter.cpp.
• ...
• DOLFIN version: 2016.2.0

Am i missing anything? is there another GPU based implementation for FEniCS?

Thank you,

The Cusp backend was removed in commit 46181526cafef78b799b85400889e9e3be611d26 in DOLFIN. It was unfortunately not mentioned in the changelog. See also this comment.
