Subject: ANN: Tachyon multithreaded raytracer ported to VMS


Hello fellow VMS'ers and others,

The Tachyon parallel/multiprocessor raytracer (
http://jedi.ks.uiuc.edu/~johns/raytracer/ ) has been partly ported to
VMS, it does not yet handle unix directories and gives an overflow on
VMS very seldom or special occasions, I may look into these later, when
I get the time and interrest again.
It's available here:
http://byron.ext.telia.se/anonymous/VMS/TDF/TACHYON_0_93_4.ZIP

VMS specific feature is using sys$getsyiw to get the number of active
CPU's and using that
to create the number of worker threads.

An Alpha VMS  7.2-1 executable is included, otherwise you'll need a C
compiler and at least
VMS 7.1 to have a "mature" pthreads-library, it's been tested on VMS
7.2-1 using an eight cpu 8400 5/625 and 7.3 two cpu 8400 5/300.
