Hiya,
I am a new user to povray. My purpose to use just for testing my cluster. I have
installed povray 3.6 on my 8 node cluster using mpich. povray works fine when
run on head node but i dont know how to run it using mpirun commond on more
then 1 processor. or do i ahve to install any patches for it which unfortunalty
i cant find becuase the website is down. I have heard that there is a build in
function in version 3.6 and i dont need any mpipov patch for that but still it
will be great help if some body tell me how to run it on differnt number of
nodes. if you need any further information please feel free to contact me
thanks a lot.

POV-Ray 3.6 does not support multithreaded rendering. POV-Ray 3.7 does.

hiya Warp,
Thanks for help. but still i m confused on how to render an image on cluster
what i mean to say is how can i allocate the job to computation node. in window
based systems it is much easier but in unix it much harder. i have installed
beta version and when i run the benchmark it just uses server processing power
rather then who clusters power. could you please tell me any examples of code
which i can write to spread the process across other machines . thanks
Depends on how adept you are at coding I think, although you might be able to
pull it off with a bash script, although I've not tried it myself. The concept
is to load povray on all your nodes and have the master computer send the
rendering commands to the nodes such that each node only renders a small
portion. Those last two steps are the tricky part.
