I'm have previously been using PyCUDA on a Tesla C2075 as part my of astrophysics research. We recently installed a Tesla K40c and I was hoping to just run the same code on the new card, however I am receiving "pycuda ._driver.LaunchError: cuLaunchKernel failed: launch out of resources" errors. A quick google search for "PyCUDA Tesla K40c" returned a minimal set of results, which led me to wonder has anyone tried running PyCUDA on this card? As the PyCUDA code works fine on an older card, I am unsure why a newer card would return an "out of resources" error, when it should have more available resources. Is there an obvious solution I have overlooked as to why the same code will not run on the new Tesla card?
