- From the same source:
-
- These were the last words of Henrik Klagges, member of a massively
- parallel group at Lawrence Livermore, ... before he realized that what
- he was saying of ALNs applied to any program with an "if-statement".
- As a result, a group is now lobbying for stricter bit-control, in the
- form of legislation that would require any "if" statement in any
- program used by the Federal Government to be executed by at least
- three massively parallel computers with over 80% American-made
- components. In a surprising about-face, the Vice-President is
- supporting the proposed legislation, in a bid to "keep US computers
- busy, and show those lazy foreigners that it's not the value of the
- bit that counts, but how you compute it".
