GPU CI testing


I changed it on our branch. Thanks!


We just merged those fixes to develop… so there will be a minor conflict when you merge in develop now, but that will be an easy one. Now testing should again work reliable on stan math.


@Bob_Carpenter @syclik matrix_gpu branch is passing the tests and ready for review!


Awesome! I hope someone else can handle this one. It’ll be a lot of config and matrix stuff, neither of which are strong points for me.


As this is the latest “GPU thread” I just wanted to post this for those that are interesed in GPU computing.
