[Radiance-general] running radiance on multiple cores

[Greg Ward]

Some people have complained about misplaced or incomplete tiles using rpiece, but I haven't been able to reproduce or find the problem.

As for varying tile brightness, this is usually caused by forgetting to specify an ambient file (rad AMBFILE variable), causing redundant and wasteful as well as inconsistent calculations.

> I have radiance running on a Linux virtual machine and I am using the rad –N option.
> Sometimes though, I happen to notice in the final image tiles of varying brightness or even misplaced tiles.
> I thought it had to do with poor synchronization because of reading and writing on the network, but it seem to happen also when I have all the files on my local drive.
