Biographical sketches of authors

Andreas Bieswanger   IBM Server Group, Schoenaicherstrasse 220, 71032 Boeblingen, Germany (anbie@de.ibm.com). Mr. Bieswanger is an Advisory Engineer working on zSeries service subsystem design. He studied computer science at the Georg-Simon-Ohm-Fachhochschule Nuernberg and graduated in 1994, receiving his Diplom-Informatiker (F.H.) degree. He joined the IBM Development Laboratory in Boeblingen that same year and began work on the design and implementation in different areas of the support element. His work currently focuses on design and evaluation of advanced server concepts.

Franz Hardt   IBM Server Group, Schoenaicherstrasse 220, 71032 Boeblingen, Germany (hardt@de.ibm.com). Mr. Hardt is an Advisory Engineer currently working on the IBM eServer hardware management console. He graduated in 1988 from the University of Mainz, Germany with an M.S. degree in mathematics, joining IBM at the Boeblingen Development Laboratory that same year. He worked on several projects in the z/OS area and also on an object-oriented framework for embedded controllers in manufacturing systems. Since 1997, he has focused on design and implementation in the hardware configuration of the support element. Mr. Hardt has been on international assignment in the IBM Endicott, New York, laboratory since 2001.

Astrid Kreissig   IBM Server Group, Schoenaicherstrasse 220, 71032 Boeblingen, Germany (kloss@us.ibm.com). Mrs. Kreissig is an Advisory Engineer currently working on IBM eServer service subsystem architecture. She graduated in 1987 from the University of Aachen, Germany, with an M.S. degree in computer science and joined IBM at the Boeblingen Development Laboratory in 1988. She worked on a variety of projects ranging from z/OS administration software to an object-oriented framework for embedded controllers in manufacturing stations. From 1993 to 1997, Mrs. Kreissig coached several object-oriented projects, working closely with the IBM OOTC. Between 1997 and 2000, she contributed to the zSeries development as a software designer and a tools team leader. Since 2000, Mrs. Kreissig has been on international assignment in the IBM Austin, Texas, laboratory.

Harm Osterndorf   IBM Server Group, Schoenaicherstrasse 220, 71032 Boeblingen, Germany (osterndo@de.ibm.com). Mr. Osterndorf is a Staff Engineer currently working on zSeries service subsystem design. He studied computer science at the Berufsakademie Stuttgart and graduated in 1990, receiving a Diplom-Ingenieur (B.A.) degree. He joined IBM at the Boeblingen Development Laboratory that same year and worked on design and implementation of AIX software in the area of banking applications and hardware until he joined the S/390 service subsystem in 1994. Currently, Mr. Osterndorf focuses on the transition of the service element code into an object-oriented design in the area of base infrastructure and components.

Gerhard Stark   IBM Application Development and Services Division, Schoenaicherstrasse 220, 71032 Boeblingen, Germany (gstark@de.ibm.com). Mr. Stark is a Software Development Engineer currently working on development of the PvC WebSphere portal server. In 1977 he joined IBM at the plant in Sindelfingen, Germany. From 1983 to 1985, Mr. Stark was on international assignment in East Fishkill, New York. He joined the Boeblingen Development Laboratory in 1986; from 1997 to 2000, he contributed to S/390 development.

Helmut Weber   IBM Server Group, Schoenaicherstrasse 220, 71032 Boeblingen, Germany (weberh@de.ibm.com). Dr. Weber is a Senior Technical Staff Member currently working on IBM eServer system design concepts. He graduated in 1979 from the University of Marburg, Germany, with an M.S. degree in mathematics and physics; he received a Ph.D. degree in mathematics from the University of Marburg in 1982. He joined IBM in 1984 at the Boeblingen Development Laboratory, where he worked on operating system concepts in the Advanced Technology Group. Between 1988 and 1999, Dr. Weber worked on most support processor development projects in the IBM Boeblingen and Endicott laboratories: S/390 systems 9370 and 9371, S/390 CMOS G1 to G6, and the zSeries z900 server. Since 1999, Dr. Weber has been on international assignment, working in the IBM Poughkeepsie laboratory.
