DABC as data acquisition framework for CBM
For development of the different software components for the CBM readout controller (ROC) [1], the Data Acquisition Backbone Core (DABC) [2] was used. The ROC board was primarily developed to read out data from nXYTER-based frontends. With a new FPGA firmware the readout of GET4/FEET frontends is also possible [3]. In addition to the existing Ethernet based data transport, an optical fibre data...
متن کاملDABC data acquisition input for slow control variables
The Data Acquisition Backbone Core (DABC) is a software framework to run DAQ with distributed event building on high performance Linux clusters [1]. There are several use cases, especially in test beam times where the setup during data taking is intentionally changed very often, and the interpretation of the acquired detector data depends on the experimental set-up. Usually, the set-up is manag...
متن کاملCore Backbone Convergence Mechanisms and Microloops Analysis
In this article we study approaches that can be used to minimise the convergence time, we also make a focus on microloops phenomenon, analysis and means to mitigate them. The convergence time reflects the time required by a network to react to a failure of a link or a router failure itself. When all nodes (routers) have updated their respective routing and forwarding databases, we can say the n...
متن کاملDevelopments for a future DAQ framework DABC
The Data Acquisition Backbone Core DABC will provide a general software framework for DAQ tasks over the next years. It serves as test bed for FAIR detector tests, readout components tests, data flow investigations (switched event building) and DAQ controls. Specifically, the system must be able to handle a triggerless experiment with large data bandwidth like CBM [1]. Additionally, it is neces...
متن کاملPEXOR Linux device driver and DABC integration
A device driver has been developed to apply the PEXOR hardware for Linux OS. It is realized as a char driver kernel module, currently for kernel versions 2.6.27. The driver operations for read() and write() implement PIO to the PEXOR on-board memory. Operation mmap() allocates kernel buffers for DMA operations and maps these to user space addresses. The pexor kernel module manages these buffers...
