PDF-CUDA Warps and OccupancyCUDA Warps and Occupancy

GPU Computing Webinar 7122011 Dr Justin Luitjens NVIDIA Corporation Dr Steven Rennich NVIDIA Corporation Fermi Architecture SM. Basically a child CUDA Kernel can be called from within a parent CUDA kernel and then optionally synchronize on the completion of that child CUDA Kernel The parent CUDA kernel can consume the output produced from the child CUDA Kernel all withou t .
