上海VLBI关联函数的现状
Current status of Shanghai VLBI correlator
摘要：
上海天文台在2014年底将其DiFX集群升级为420个CPU内核和432 TB存储系统。还建立了原始数据传输的国际网络连接。IVS会话的常规操作包括CRF、AOV和APSG系列于2015年初开始。关联函数除了用于IVS观测外，还用于与中国VLBI网和国际VLBI联合观测的天体物理和天体测量计划。它还与新建的天马65米射电望远镜合作，并于2015年底成功发现了高达X/Ka和Q波段的条纹。为将来的高数据速率和海量数据关联任务规划了一个更强大的平台。
英文摘要：
Shanghai Astronomical Observatory has upgraded its DiFX cluster to 420 CPU cores and a 432-TB storage system at the end of 2014. An international network connection for the raw data transfer has also been established. The routine operations for IVS sessions including CRF, AOV, and APSG series began in early 2015. In addition to the IVS observations, the correlator is dedicated to astrophysical and astrometric programs with the Chinese VLBI Network and international joint VLBI observations. It also worked with the new-built Tianma 65-m radio telescope and successfully found fringes as high as at X/Ka and Q bands in late 2015. A more powerful platform is planned for the high data rate and massive data correlation tasks in the future.
