Information and control system of ČSM Coal Mine preparation plant
Published in Vladimír Strakoš, Vladimír Kebo, Radim Farana, Lubomír Smutný, Mine Planning and Equipment Selection 1997, 2020
The sales control system at ČSM Coal Mine was developed by ATP Soukup in 1996 and put into operation in the beginning of 1997, after 2 months’ trial operation. Compared with the preparation plant control system run in real time on PDP 11/83 computer (RSX-11M+ operating system) the sales control system allows data evaluation in an unlimited period. It is based on Alpha Server 1000/266 computer supplied by Digital. The computer runs under Windows NT 3.51 operating system and the database Microsoft SQL server 6.0 was selected. The data important for the sales control gathered by the PDP computer from the process and dispatching level of the preparation plant control system are transferred to the Alpha computer database. For the communication between the two different kinds of operating systems ATP Soukup has developed a system of communication tasks based on DECnet with Pathworks software working in the form of task-to-task report exchange. This type of connection allows data acquisition and transfer from any equipment or process connected to the PDP computer (automatic track weighers, WILPO quick quality analyzer, road weigher, sensors in cleaned coal bins, graphic stations, etc.) or data transfer from the sales control system to the preparation plant control system (e.g. loading plan and its alterations initiated from the client workplace in Karbonia trading company are displayed on the preparation plant control room terminals or list of empty wagons from OKR — Transport is printed out at the track weigher workplaces after the data transfer). The communication tasks are written in Microsoft Visual C++ on the Alpha (Windows NT) computer and in Fortran 77 on the PDP computer, As indicated earlier the sales control cannot be separated from the preparation plant control so the Sales Department uses also the PDP 11/83 computer applications. Both control systems are interlinked and partly coinciding.

Personal reflections on 50 years of scientific computing: 1967–2017
Published in International Journal of Parallel, Emergent and Distributed Systems, 2020
While distributed computing is as old as networking (DEC famously advertised that with the VAX and DECnet, ‘the network is the computer’), new concepts and technologies emerged, generically called grid computing [11]. The new technologies were both high level (e.g. automatic acquisition of a needed service) and low level (e.g. remote authentication), and intended to expand computing capability (e.g. solve a larger problem) or improve reliability (e.g. provide redundant sources for some service) or increase machine utilisation (e.g. by routing a task to a lightly loaded system). The major players in grid computing were Globus (Argonne National Laboratory), Legion (University of Virginia), Condor (University of Wisconsin), and SORCER (National Bureau of Standards, now known as the National Institute of Science and Technology).
