Description
I will present progress on the development of the radiation module of cuHARM, a finite volume code which solves the general relativistic radiation magnetohydrodynamic equations in curved space-time. The specific intensity is resolved in frequency and in direction on a geodesic grid. I will describe the challenges linked to this discretization, which does not rely on the widely used M1 or M2 closure relations or on the assumption of grey transport. I will further discuss the implementation on graphics processing units (GPUs) to accelerate the computation, with an emphasis on performance, bottlenecks and scalability. I will conclude the talk by discussing future developments.
