暗能量调查数据管理系统:处理框架
The Dark Energy Survey Data Management System: The Processing Framework
摘要:
暗能量调查数据管理(DESDM)系统将在五年的运行期内处理和存档来自暗能量调查(DES)的数据。本文重点介绍了一种新的适应性强的处理框架,开发执行高度自动化,高性能的数据并行处理。新的处理框架已被用于处理45个夜晚的模拟DECam超新星成像数据,并被广泛用于DES数据挑战4,在那里它被用来处理数千平方度的模拟DES数据。
英文摘要:
The Dark Energy Survey Data Management (DESDM) system will process and archive the data from the Dark Energy Survey (DES) over the five year period of operation. This paper focuses on a new adaptable processing framework developed to perform highly automated, high performance data parallel processing. The new processing framework has been used to process 45 nights of simulated DECam supernova imaging data, and was extensively used in the DES Data Challenge 4, where it was used to process thousands of square degrees of simulated DES data.
