Research Overview: Thread Coarsening as an Optimization Technique for GPUs
ince fine-grained programming model is preferred for GPUs in order to launch thousands kernels in parallel, often times, a thread for GPUs underutilizes dedicated resources such as registers or instruction level parallelism. Thread coarsening merges workloads of two or more threads into one thread so that the hardware can run more efficiently. Also, this achieves elimination of redundant memory operations and computations as common values can be shared after coarsening.
