Hello,

I don't think that you should need to change distributions just to setup 
bproc, I found the installation of bproc quite simple.  We have a small 
educational cluster at school and we've been using bproc for several 
months now.  It lends it self really well for a diskless setup and as a 
bonus LAM/MPI can integrate with bproc so that MPI applications could also 
run on top of it.  I think that you would be pleased with Bproc.

BTW, it took us less than a day to convert our "traditional" cluster into  
a Bproc one.

Best of luck,
