QYMSYM: GPU accelerated 2nd order hybrid symplectic integrator that permits close encounters.
This is a parallel code running with CUDA on a video card that puts the many processors on board to work while taking advantage of fast shared memory.
It is meant to do the same thing as John Chambers' code
mercury6 but in parallel on the GPU.
