Tackling the complex set of tasks outlined above has made some changes to the CN group structure desirable. Corresponding to the two principal components identified above, two new groups have been created: Physics Data Processing (PDP), under Les Robertson; and Desktop Computing Infrastructure (DCI) under Chris Jones. In addition, a new Central Infrastructure and Operations (CIO) group under Dave Underhill will take care of the shift operations for the equipment in the computer centre and the infrastructure in that building. The old Consultancy and Operations (CO) and Software (SW) groups have been dissolved, with their members moving, in the main, to these three new groups. The disappearance of CO group underlines the heightened operational responsibility that the new groups will bear for the services they support. The Applications Software (AS) group, under its new leader Tony Osborne, has taken on additional responsibility for database infrastructure and has been renamed Application Software and Databases (ASD). David Jacobs replaces Tony Osborne as Deputy Division Leader and Jean-Claude Juvet becomes DPO on the retirement of Jacques Spalter. The Communications Systems (CS) group (Brian Carpenter) continues with an unchanged mandate, as does the Computing for Engineering (CE) group, under its new leader Chris Eck. Amongst those who have taken on special responsibility should be mentioned Harry Renshall, who has been named Physics Services Manager with the task of ensuring that PDP services meet user expectations, and Miguel Marquina, who takes over the responsibility for the User Consultancy Office.
I should like to take this opportunity to thank all of those people who held, or will hold, positions of responsibility in the old and new structures. Special thanks and best wishes go to René Brun and Sverre Jarp who have reached the end of their mandate as group leaders. I am sure that they will continue to serve CERN (and its users) well in their new functions.
I am sure that I can speak on behalf of the division and also on behalf of many computer users in thanking Jacques Spalter, who will retire at the end of January 1994 after 25 years as DPO, first in DD Division and then in CN. His advice, whether on personnel or financial matters, has always been extremely useful, and has certainly helped to improve the efficiency of CN and of CERN as a whole. We wish him a long and enjoyable retirement.
