Abstract
- Motivation The data deluge of high-throughput sequencing (HTS) has posed great challenges to data storage and transfer. Many specific compression tools have been developed to solve this problem. However, most of the existing compressors are based on central processing unit (CPU) platform, which might be inefficient and expensive to handle large-scale HTS data. With the popularization of graphics processing units (GPUs), GPU-compatible sequencing data compressors become desirable to exploit the computing power of GPUs. Results We present a GPU-accelerated reference-free read compressor, namely CURC, for FASTQ files. Under a GPU–CPU heterogeneous parallel scheme, CURC implements highly efficient lossless compression of DNA stream based on the pseudogenome approach and CUDA library. CURC achieves 2–6-fold speedup of the compression with competitive compression rate, compared with other state-of-the-art reference-free read compressors. Availability and implementation CURC can be downloaded from https://github.com/BioinfoSZU/CURC. Supplementary information Supplementary data are available at Bioinformatics online.
