Features of the new MBS Production Version 6.2N.Kurz1, J.Adamczewski-Musch1, and S.Linev11CSEE, GSI, Darmstadt, GermanyIntroductionThe general purpose data acquisition system MBS hasbeen used in the past by a vast majority of GSI experi-ments. It will also be applied by many experiments at FAIR(e.g. NUSTAR) for data taking and for tests of future FAIRdetector systems. A new production version 6.2 has beenrolled out in 2013 to accommodate the requirements of ex-periments. Its new features and improvements, like supportof new processor boards, PCI Express, Linux, and 10GbitEthernet will be described. For detailed information theMBS homepage (www.gsi.de → @work → Experiment-Elektronik → Datenerfassung→ MBS) and release notes6.2 therein can be consulted.New FeaturesLinux for PCs: Currently the DEBIAN Linux versionswith code names Lenny, Squeeze and Wheezy are fullysupported as 32 bit machines. They have been set up toboot and run diskless as all MBS nodes.10Gbit Ethernet: Due to ever increasing data rates, 10Gigabit Ethernet has become inevitable and is now sup-ported on PCs for all Linux flavours mentioned above. In atypical MBS setup a data throughput of 700 MB/s could beachieved without further software optimization.Linux for RIO4 VME processor: Up to MBS version5.0 LynxOS was the only supported real-time operatingsystem available. Since the existence of LynxOS for futureVME processor boards seems not be guaranteed, an efforthas been undertaken to run MBS with Linux on the RIO4.A kernel module for the TRIVA VME trigger module hasbeen developed. MBS is now fully supported. Single cy-cle VME A32D32 read accesses show a 10% higher speedwith Linux compared to LynxOS. Network write speed istwo times faster on Linux (80 MB/s). MBS template userreadout functions are available.IPV VME processor board: According to the supplier,the VME processor RIO4 will be purchasable for someyears, but a follow up model seems not to be available at thetime being with the performance characteristics required.In addition, the PPC processor chip utilized on the RIO4will not be developed further. In a survey, alternative VMEprocessor boards have been assessed.The IPV 1102 from the company IOxOS has been iden-tified as a candidate for the future. Its heart is a Pow-erPC P2020 from Freescale. Again a kernel module forthe TRIVA trigger module has been developed and the IPC1102 is now fully integrated into MBS. Simple templateMBS user readout functions and VME mapping examplesfor more advanced VME block accesses are available.PCI Express based MBS readout systems: Prior toMBS version 6.2, commodity PC hardware was used solelyas MBS event-builders. New hardware developments madeby CSEE department of GSI (www.gsi.de → @work →Experiment-Elektronik → Digitalelektronik → Module)required to extend the MBS PC capabilities as front endreadout processors.The PCI Express data concentrator board PEXOR andtrigger module TRIXOR are the base of this new read-out system. LynxOS drivers and Linux kernel modulesfor PEXOR and TRIXOR, and MBS user readout func-tions have been developed. They allow to control and read-out frontend electronics (FEBEX, GEMEX) connected toPEXOR via optical links.The TRIXOR has identical functionality as the VMEtrigger module TRIVA. It is possible to interconnect anynumber of TRIXOR and TRIVA modules on a commontrigger system, to setup highly flexible MBS DAQ systems.New sorting modes in MBS time sorter process m to:The MBS time sorter and event-builder task is used to com-bine data from independent DAQ systems based on timestamp information. Up to now the TITRIS time stamp sys-tem developed by CSEE was used for this purpose.Three new Foreign DAQ systems required to implementthree new time stamp sorting algorithms: To combine thePANDA GEM-TPC system with FOPI an algorithm basedon COMPASS (CERN) hardware was implemented. TheEURICA experiment at RIKEN required an algorithm tocombine BIGRIPS and MBS systems with the LUPO timestamper from RIKEN. Finally, AGATA and RISING MBSDAQ was combined using the AGAVA/GTS hardware pro-vided from the AGATA community.Currently supported MBS processorplatformsLynxOS 2.5: CVC, E7, RIO2, PCLynxOS 3.1: RIO3LynxOS 4.0: RIO4, PCLinux Debian 2.6: PCLinux Debian 3.2: PCLinux Sugarhat 2.6: RIO4Linux DENX 3.3: IPVGSI SCIENTIFIC REPORT 2013 FG-CS-03doi:10.15120/GR-2014-1-FG-CS-03 FAIR@GSI 373
