Progress on the Compute Node based DAQ System for PANDA — •Björn Spruck1, Sören Fleischer1, Thomas Geßler1, Wolfgang Kühn1, Jens Sören Lange1, Zhen’An Liu2, David Münchow1, Hao Xu1,2, and Jingzhou Zhao2 — 1II. Physikalisches Institut, Universität Gießen — 2IHEP, Beijing
The PANDA detector will be located at the future FAIR facility in Darmstadt. As PANDA has been designed without a global trigger, a large amount of data (≤200 GB/s @ 2· 107/s interaction rate) has to be distributed and processed in real time. A hardware platform capable of processing this amount of data is the ATCA based Compute Node (CN) developed in close cooperation between IHEP Beijing and our institute. Each node consists of an xTCA carrier board and four AMC/µTCA daughterboards. The carrier board supplies the high bandwidth connectivity between the daugtherboards and the other CNs in the shelf by RocketIO links. In the current prototype design, each AMC board is equipped with a Virtex5FX70T, 4 GB of memory, GBit ethernet and two optical links which allow for high data transfer rate. Beside the event builing, the CNs will run algorithms for cluster finding in the calorimeter data, online tracking and based on these make trigger decisions.
This talk will not only focus on the current hardware and future developments, but also on the setup and performance of our test system, including the status of the algorithm developments.
