Hello David,

thanks for your reply. Indeed, I haven't used the partitioner. I also
have problems importing my data, the image I get doesn't make sense at
all.

I'm a student in the CS department of Princeton, and I'm working on a
new benchmark suite for shared memory computers. I wanted to use OpenDX
as one of the benchmark programs, but it proved to be difficult to set
up and use. I'd appreciate if I could get some help.

The benchmark should run approx. 20 seconds with a single CPU on a
modern computer. The test data I wanted to use first is the head from
the Siggraph Volume Visualization Data Sets:

http://www.siggraph.org/education/materials/vol-viz/3dhead.zip

I've used the following (nonfunctional) OpenDX .general file to import
my data:

file = /home/cbienia/3dhead
grid = 109 256 256
format = msb ieee
interleaving = field
majority = column
field = Density
structure = scalar
type = short
dependency = positions
positions = 0, 1, 0, 1, 0, 1
end

I'm also looking for a visual program that does the volume rendering in
parallel. The one I wrote myself doesn't work at all. Does anybody have
such a program available? I'd appreciate if I could get a copy.

Thanks a lot for the help in advance!

- Chris
