  Biography
Per Brinch Hansen is one of a handful of computer pioneers who was responsible for advancing both operating systems development and concurrent programming from ad hoc techniques to systematic engineering disciplines.
Brinch Hansen received the master’s degree in electrical engineering from the Technical University of Denmark in 1962.
Since 1972 Brinch Hansen has held professorial appointments in computer science at California Institute of Technology, University of Southern California, and University of Copenhagen, Denmark.

  Per Brinch Hansen - Wikipedia, the free encyclopedia
Syracuse University, NY The Danish-American computer scientist, Per Brinch Hansen, was born November 13, 1938, in Frederiksberg, a suburb of Copenhagen, Denmark.
Per Brinch Hansen is one of the pioneers of concurrent programming (also known as parallel programming) and operating systems (kernels).
In the 1960s, Per Brinch Hansen worked at the Danish computer company Regnecentralen, first in the compiler group headed by Peter Naur and Jørn Jensen, and, later, as the chief architect of the RC 4000 minicomputer and its renowned operating system kernel (RC 4000 Multiprogramming System).

His name should be typed with a comma: "Brinch Hansen, Per" To understand why, you must understand how BibTeX handles names (for what follows, a "name" corresponds to a person).
For example the First part of Per Brinch~Hansen's name has the single token "Per"; the Last part has two, "Brinch" and "Hansen"; and the von and Jr parts are empty.
If you had typed "Per Brinch Hansen" instead, BibTeX would erroneously think "Brinch" were a First-part token, just as "Paul" is a First-part token in "John~Paul Jones".

Keywords: programming languages, parallel programming; data parallelism, High Performance Fortran, message passing In the March issue of this journal, Per Brinch Hansen devoted an article [1] to an evaluation of High Performance Fortran (HPF).

Per Brinch Hansen introduced an interesting idea in his RC4000 operating system (see his 1973 OS textbook).
Instead of having interrupt routines do any work, all useful work was done in high-priority processes scheduled with the normal system scheduler.
The emphasis in both the lecture and in Brinch Hansen's discussion of disk scheduling (see section 5.3) is on what order to visit the different cylinders of the disk drive.

 Multiple-length Long Division
The best one I found is in the tutorial "Multiple-length Division Revisited: a Tour of the Minefield" written in 1994 by Dr. Per Brinch Hansen and published in the journal Software Practice and Experience, Vol24(6), June 1994.
The Hansen paper largely solved the problem for me because, not only does he explain the algorithms for long division, he thoughtfully includes Pascal code for an implementation.
I'm not going to try to explain the details, download the paper and spend a few hours working through hid 23 page tutorial if you are interested.

In data base systems, computer networking, and small operating systems, substantial industrial efforts have generally been required to make new ideas and approaches entirely credible.
Per Brinch Hansen's work on Concurrent PASCAL illustrates this pessimistic remark.
In many ways this work, which built on such fundamental concepts as monitor and process and incorporated them into an interesting parallel processing language, was excellent.

 High-Performance Server Architecture
The purpose of this document is to share some ideas that I've developed over the years about how to develop a certain kind of application for which the term "server" is only a weak approximation.
The only realistic alternative for a scalable system is to limit the number of active threads so it's (usually) less than or equal to the number of processors.
One list per processor can be even better, due to cache-warmth considerations, but only works if threads cannot be preempted.

would (erroneously) think ``Brinch'' were a First-part token, just as ``Paul'' is a First-part token in ``John Paul Jones'', so this erroneous form would have two First tokens and one Last token.
