Review InformaticsNext-generation sequencing: big data meets high performance computing

•Analysis of massive NGS datasets poses difficult computational challenges.•Big data algorithms are often adapted for NGS analysis.•HPC becomes pivotal as NGS transcends from research labs to medical applications.

The progress of next-generation sequencing has a major impact on medical and genomic research. This high-throughput technology can now produce billions of short DNA or RNA fragments in excess of a few terabytes of data in a single run. This leads to massive datasets used by a wide range of applications including personalized cancer treatment and precision medicine. In addition to the hugely increased throughput, the cost of using high-throughput technologies has been dramatically decreasing. A low sequencing cost of around US$1000 per genome has now rendered large population-scale projects feasible. However, to make effective use of the produced data, the design of big data algorithms and their efficient implementation on modern high performance computing systems is required.
