PPT-Writing Efficient CUDA Programs

Martin Burtscher Department of Computer Science HighEnd CPUs and GPUs Xeon X7550 Tesla C2050 Cores 8 superscalar 448 simple Active threads 2 per core 48 per core Frequency 2 GHz 115 GHz. 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 heterogeneous programming.
