Fyi, I'm willing to contribute to the GSoC effort as well. I can sponsor
access to the variety of hardware we have at the Minnesota Supercomputing
Institute. Including single and multi-GPU nodes and
workstations (m2070s, k20s, k2s, and quadro variants), single and multi
Xeon phi 5110p nodes, and nehalem and sandy bridge nodes.
Let me know if the need arises. I'm also open to mentor if needed.
Cheers,
