Subject: [9fans] 64 bit arithmetic
Date: Wed, 14 Jun 2000 10:02:27 +0000 [thread overview]
Message-ID: <39474F43.82A4F0C2@yorvic.york.ac.uk> (raw)
From http://plan9.bell-labs.com/magic/man2html/1/2c
The compilers accept long long variables as a 64-bit type. The standard header
typedefs this to vlong. Arithmetic on vlong values is usually emulated by a
run-time library.
What's the overhead on this?
plan 9 will be adopted for Beowulf-type applications, as this model
is naturally incorporated within the system's design.
However, most of these applications are numeric intensive and often
require 64-bit arithmetic.
is there any work internally in Bell Labs on native 64 bit libraries?
