Abstract

Abstract We developed a pulsar search pipeline based on PulsaR Exploration and Search TOolkit (PRESTO). This pipeline simply runs dedispersion, Fast Fourier Transform (FFT) and acceleration search in process-level parallel to shorten the processing time.With two parallel strategies, the pipeline can highly shorten the processing time in both normal searches and acceleration searches. This pipeline was first tested with Parkes Multibeam Pulsar Survery (PMPS) data and discovered two new faint pulsars. Then, it was successfully applied in processing the Five-hundred-meterAperture Spherical radio Telescope (FAST) drift scan data with tens of new pulsar discoveries up to now. The pipeline is only CPU-based and can be easily and quickly deployed in computing nodes for testing purposes or data processing.
