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?
