Hi Chris, Hmm, maybe Pleiades sets OMP_NUM_THREADS=1 by default. Can you check: echo $OMP_NUM_THREADS If it is either unset or set to 1, could you give it a shot with export OMP_NUM_THREADS=12? The HT shouldn't help too much. Best, Sam On Wed, Jun 13, 2012 at 8:14 PM, Christopher Moody <cemoody@ucsc.edu> wrote:
Hi Matt, Yep, this is an ART dataset. I had a node running with 12 (24 with HT) cores at NASA Pleiades. It didn't go above 4% (=1/24) usage, which indicates means it likely did not use more than one core (but I didn't tell it to). If there's a parallel version of the script I can try it out tonight, and see the scaling.

Chris, is this an ART dataset rendering? I love it. Great work. And, did you note on your machine what the load went up to? Did it scale with the numebr of cores okay?

Works for me!
On one core, no_ghost=True, kd-Tree took 5 seconds, ray casting 56 seconds. Impressive.

Also, for what it's worth, John, Sam and I have been working on creating a movie sequence with this in HiDef for a display project. Once that's done we're going to be posting the movie, the original scripts, and potentially even a screencast of how one goes about doing a complex volume rendering.

Hi all,
Here's a sample script that exposes a few of the new features such as opacity and the map_to_colormap function. http://paste.yt-project.org/show/2458/
I'll see if I can get some more scripts written in a portable way.
Cheers, Sam

Matt,
I'll give it a whirl... it may take a day or two.
