GateKeeper-GPU: Fast and Accurate Pre-Alignment Filtering in Short Read Mapping

We introduce GateKeeper-GPU, a fast and accurate pre-alignment filter that efficiently reduces the need for expensive sequence alignment. GateKeeper-GPU improves the filtering accuracy of GateKeeper, and by exploiting the massive parallelism provided by GPU threads it concurrently examines numerous sequence pairs rapidly. GateKeeper-GPU is available at https://github.com/BilkentCompGen/GateKeeper-GPU. Please refer to the preprint at arXiv:2103.14978 for more information.
