Report from Ameya, who cannot attend today:

I'm starting to make progress on implementing the parton grouping on the CUDA plugin. I've managed to define the quark/anti-quark struct that I replicated from the C++ version and now I'm working on changing the wavefunctions to incorporate this modified object.  I'm using a u d > u d scattering process as a proxy before I make changes to the template code.

    Reached out to Jin for help with his framework, I'll follow up again this week.
    I'll test out the TT+jets gridpack to see if the FPExecption during the gridpack production had something to do with the error I was seeing last week.
