“…4 The comedi library ͑GPL͒, distributed in a free manner, is used to establish a communication with the acquisition hardware. 5 This library allows the access to the data acquisition hardware with a reduced set of functions. The concept and the operating philosophy are analogous to the ones described in the previous section and, therefore, there are disadvantages in the sense that all the tasks directly generated by LABVIEW are not making use of the system real-time functionality.…”

Remote participation in fusion experiments is becoming more and more widespread. From the point of view of the data processing that each experiment generates, remote participation increases the present needs of existing systems. On the one hand, these systems must be able to acquire the data from each discharge ͑with hundreds of channels and high-sample frequencies͒ and, on the other hand, they must be able to compress, analyze, and process data in as short period of time as possible. This would mean a decrease in network bandwidth use when sending results to remote investigators, a considerable saving of space in the local database, and a reduction of computation time in the server. Furthermore, in remote participation experiments, the system would allow each user to configure their own measures and analyses ͑downloading their own high-level programs in the system-writing in 4GL languages, for example in LABVIEW-and receiving the processed data as soon as possible͒. What is proposed as a solution for data processing in experiments with remote participation ͑that will be applied in the stellarator type device ͑TJ-II͒ of the Research Center for Energy, Environment, and Technology ͑CIEMAT͒, of Madrid Spain, is a distributed system that guarantees noise immunity and electromagnetic shielding ͑for example, based on several PCI ͑peripheral component interconnect͒ extensions for instrumentation ͑PXI͒ chassis with several digitizer boards in each one͒. It is not possible to process all data from the system's own controller. Therefore, the following alternative will be presented: The design of the development of a processing board, that works in a peripheral PXI slot ͑nonsystem slot͒, running a real-time operating system ͑WNTϩRTX, RT-LINUX,...͒, that communicates by PXI bus with the controller. In this way, the needs of data processing in remote participation experiments can be fulfilled.

“…At the time of ISPI project start, the SOAR telescope had chosen National Instruments LabVIEW 15 under RTLinux 16 as its development environment for observatory control. The telescope control system was contracted to Imaginatics, Inc. 17,18,19 . CTIO staff seconded to the SOAR Consortium were developing instrument control software for the SOAR Optical Imager (with its SDSU II controller) using ArcVIEW, a LabVIEW-based proprietary software package also produced by Imaginatics 20 .…”

The new operations model for the CTIO Blanco 4-m telescope will use a small suite of fixed facility instruments for imaging and spectroscopy. The Infrared Side Port Imager, ISPI, provides the infrared imaging capability. We describe the optical, mechanical, electronic, and software components of the instrument. The optical design is a refractive camera-collimator system. The cryomechanical packaging integrates two LN 2-cooled dewars into a compact, straightline unit to fit within space constraints at the bent Cassegrain telescope focus. A HAWAII 2 2048 x 2048 HgCdTe array is operated by an SDSU II array controller. Instrument control is implemented with ArcVIEW, a proprietary LabVIEW-based software package. First light on the telescope is planned for September 2002.
