| 中文摘要 | To meet the need of bio-computing, such as high concurrency and large data processing, the data services in CNGrid workflow has to be optimized. According to the experiments, the open-source RDBMS (relational database mangement system) used in original architecture was not well adapted to high concurrent requests and large data processing, and has become the bottleneck of performance. In view of this, we analyzed the actual need of data services in grid workflow, from functionality and performance perspectives, and propose a new data service component: TreapDB, which uses mmap and append only log-data file to reduce the I/O waiting time, and meet the business needs of process data querying. Experiments show that, after the optimization of data services, the overall performance of CNGrid workflow increase greatly, and it has been applied successfully in CNGrid bio-community. |
