摘要:

探测器和计算技术的进步为应用研究和基础科学提供了新的机会。同时,实验数据的三个V(体积,速度和多样性)和计算任务的规模的急剧增加产生了对实验设施中新的实时的【形】处理系统的需求。最近,Spark-MPI方法将Spark数据密集型平台与MPI高性能框架连接起来,解决了这一需求。与现有的数据管理和分析系统相比,Spark引入了一种基于弹性分布式数据集(RDD)的新中间件,该中间件将各种数据源与高级处理算法解耦。RDD中间件极大地扩展了数据密集型应用程序的范围,从SQL查询扩展到机器学习再到图形处理。Spark-MPI通过使用进程管理接口的MPI应用程序进一步扩展了Spark生态系统。本文探讨了这个集成平台的背景下,在线重叠关联和断层重建管道。

英文摘要:

Advances in detectors and computational technologies provide new opportunities for applied research and the fundamental sciences. Concurrently, dramatic increases in the three Vs (Volume, Velocity, and Variety) of experimental data and the scale of computational tasks produced the demand for new real-time processing systems at experimental facilities. Recently, this demand was addressed by the Spark-MPI approach connecting the Spark data-intensive platform with the MPI high-performance framework. In contrast with existing data management and analytics systems, Spark introduced a new middleware based on resilient distributed datasets (RDDs), which decoupled various data sources from high-level processing algorithms. The RDD middleware significantly advanced the scope of data-intensive applications, spreading from SQL queries to machine learning to graph processing. Spark-MPI further extended the Spark ecosystem with the MPI applications using the Process Management Interface. The paper explores this integrated platform within the context of online ptychographic and tomographic reconstruction pipelines.
