Do you do raytracing on a ES/9000 ?? I ported one of the previous
versions of POV-Ray to MVS/ESA, what OS are you running under ?? I
found my source conversion code recently and was wondering if a port
would be worth-while speed-wise, after all the IBM mainframes aren't
known for their floating point performance. Back when a 486/50 MHz was
a fast machine my port ran 7 times faster on a IBM 3090 Model 180. The
shift from bipolar to cmos technology in the mainframes ate a lot of
mips so I doubt that a port to the (almost) current version of ES/9000
HW would be much faster than a 1 GHz PC. At the time I made the port
PCs didn't have much memory, a 4 MB pc was a big machine, we had 256
MB on the mainframe.
