A survey of the available QP methods suitable for the on-line solution of MPC optimization problems is given, with emphasis on first-order methods, which have been recently considered as prime candidates for fast online MPC control. Using a modification of the QP solver QPgen, a five-fold speed-up compared to the state-of-the-art commercial solver CPLEX was achieved, with peak computation times below 10 ms using a four-core Intel processor.","PeriodicalId":383702,"journal":{"name":"2016 IEEE-NPSS Real Time Conference (RT)","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114572463","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The prototype of the DAQ is based on a Xilinx Vertex-6 FPGA evaluation board. The DAQ system has three parts: acquisition, cache, and data up-link. Acquisition is the interface to the high-speed random data, and we use Gigabit Transceiver (GTX) in FPGA to deserialize the random data. The 1Gbps high speed serial random data in each channel is deserialized into 62.5Mbps with 16bit width parallel data. The low speed parallel data can be handled by the FPGA code and cache the data in an external DDR3 memory. When enough random data is stored, the random data is upload to PC via Gigabit Ethernet for the finial verification. The BERT test shows that the total data error rate of the data link in the prototype is less than 6.25×10-1° with 1Gbps input. The prototype can cache up to 16Gbits random data with 1Gbps serial input, and it meets the requirements of the data acquisition for one channel of the random number generator and proves the DAQ structure.","PeriodicalId":383702,"journal":{"name":"2016 IEEE-NPSS Real Time Conference (RT)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124213460","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The system architecture incorporates two levels of hardware with FPGA-embedded system control and inline data processing. The front-end unit is a 30-channel circuit board that holds five PSEC4 ASICs, a clock jitter cleaner, and a control FPGA. The analog bandwidth of the front-end signal path is 1.5 GHz. Each channel has an on-chip threshold-level discriminator that is monitored in the FPGA, from which a flexible on-board trigger decision can be formed. To instrument larger channel counts, a `back-end' 6U VME32 control card has been designed. Called the `Central Card', it incorporates an Altera Arria-V FPGA that manages up to 8 front-end cards using one or two CAT5 network cables per board, which transmits the clock and communicates data packets over a custom serial protocol. Data can be read from the Central Card via USB, Ethernet, or dual SFP links, in addition to the VME interface. The Central Card can be configured as either Master or Slave, allowing one Master to receive data from up to 8 Slaves, with each Slave managing 8 30-channel front-end cards, allowing a single VME crate to control up to 1920 channels of the PSEC4 chip.","PeriodicalId":383702,"journal":{"name":"2016 IEEE-NPSS Real Time Conference (RT)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129683534","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Followed by the first KOTO physics run in May 2013 with 24 kW beam power, we upgraded the KOTO data acquisition system in 2015 to accommodate efficient and reliable data collection with higher beam intensities. Lossless data compression inside the ADC modules was implemented to reduced the size of data packets. The lossless data compression enhanced the data collection rate by a factor of three. We designed a new software trigger, which consists of 47 computer nodes. It uses Infiniband hardware with MPI protocol to establish mesh network within the computer cluster and parallel data processing. The upgrades of the KOTO data acquisition system were commissioned in 2015 and used to successfully collect data with beam intensity up to 42 kW.

Its main aim is to study the behavior of strongly interacting matter and the quark gluon plasma. ALICE is preparing a major upgrade and starting from 2021, it will collect data with several upgraded sub-detectors (TPC, ITS, Muon Tracker and Chamber, TRD and TOF). The ALICE DAQ read-out system will be upgraded as well, with a new read-out link called GBT (GigaBit Transceiver) with a max. speed of 4.48 Gb/s and a new PCIe gen.3 ×16, interface card called CRU (Common Read-out Unit). Several test beams have been scheduled for the test and characterization of the prototypes or parts of new detectors. The test beams usually last for a short period of one or two weeks and it is therefore very important to use a stable read-out system to optimize the data taking period and be able to collect as much statistics as possible. The ALICE DAQ and CRU teams proposed a data acquisition chain based on the current ALICE DAQ framework in order to provide a reliable read-out system. The new GBT link, transferring data from the front-end electronics, will be directly connected to the C-RORC, the current read-out PCIe card used in the ALICE experiment. The ALICE DATE software is a stable solution in production since more than 10 years. Moreover, most of the ALICE detector developers are already familiar with the software and its different analysis tools. This setup will allow the detector team to focus on the test of their detectors and electronics, without worrying about the stability of the data acquisition system. An additional development has been carried on with a C-RORC-based Detector Data Generator (DDG). The DDG has been designed to be a realistic data source for the GBT. It generates simulated events in a continuous mode and sends them to the DAQ system through the optical fibers, at a maximum of 4.48 Gb/s per GBT link. This hardware tool will be used to test and verify the correct behavior of the new DAQ readout card, CRU, once it will become available to the developers. Indeed the CRU team will not have a real detector electronics to perform communication and performance tests, so it is vital during the test and commissioning phase to have a data generator able to simulate the FEE behavior. This contribution will describe the firmware and software features of the proposed read-out system and it will explain how the read-out chain will be used in the future tests and how it can help the development of the new ALICE DAQ software.","PeriodicalId":383702,"journal":{"name":"2016 IEEE-NPSS Real Time Conference (RT)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122251789","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A dual-phase liquid xenon Time Projection Chamber (TPC) shielded below 1400 m of rock at the Gran Sasso underground laboratory in Italy serves as both target and detector. The TPC is inside a 10 m high by 9.5 m diameter water Cherenkov detector serving as an active muon veto. The Slow Control system is based on industrial process control hardware and software. It is now being used to commission the detector. The system provides secure monitoring and control by collaborators, shifters and experts at both local and remote locations. 3.5 tons of liquid xenon requires extreme care to guard the safety of the instrumentation and to prevent the loss of any of the high value xenon. The system consists of a distributed architecture of networked local control units with touch panels for local control. Critical operations can be guarded by requiring specific conditions to be satisfied before they are allowed to be executed. Two Supervisory Control And Data Acquisition (SCADA) computers provide active-passive redundancy. All operating parameters and their history are stored and can be displayed. Alarm messages are sent by email, cellular network and by pre-recorded voice over land telephone lines.
