Qualifications : Diploma in Mathematics, 1989
Present Position : Currently senior technical manager in the operating
systems department's competence center.
In Past : TPF (IBM's
transaction processing operating system) senior systems programmer
Experience : His
experience consists mainly of many years of TPF system programming.
TPF does not ship with builtin and/or freely available tools like
Linux does. However, TPF does ship with (almost) all source files
written in C and assembly language. He therefore had the
opportunity of writing a couple of memory and CPU consumption tools
and drivers in order to measure performance and to find bottlenecks
in our current implementation. His latest achievement was a 5%
overall CPU gain by rewriting private heap management routines
(malloc/free) on TPF 4.1. One other major field of experience is
hardware integration and perturbation testing, which he have been
doing for almost all new storage and CPU equipment received for
running TPF in the last ten years.
Hobbies : Sudoku
game, listening music, singing as a choir member, and
