Classification: UNCLASSIFIED Caveats: NONE No, I'm not able to share either ... I'm going to try to find a similarly sized dataset that might be more readily available. Although, there's not really an easy way to share a dataset with 1024 spcth files .....
We are having an additional issue with this same dataset .... loading the dataset using less than 80 servers (so there are no holes in the geometry) we are creating a simple animation. There are several hundred timesteps of data and we are able to interactively march through time and see the animation. However, when trying to save out a movie, the frames suddenly go blank. We tried saving out as PNG files, and the first 22 timesteps dumped fine, and then we started saving out solid black images. We restarted ParaView and started dumping out JPEG frames, and we got out to timestep 100 and it again started dumping black frames. Interactively viewing the data, all of the timesteps are valid - is there a memory leak or something similar that's causing the renderer to hose up? -----Original Message----- From: Utkarsh Ayachit [mailto:[email protected]] Sent: Tuesday, August 27, 2013 10:26 AM To: Angelini, Richard C (Rick) CIV USARMY ARL (US) Cc: Scott, W Alan; [email protected] Subject: Re: [Paraview] [EXTERNAL] extract CTH parts (UNCLASSIFIED) Rick, Coincidentally, I am looking at the CTH parts class of filters right now. Can you share the data or the images with the holes?

It doesn't matter how I distribute those 80 servers - I can do 16 processes on 5 nodes, 8 processes on 10 nodes and it works. If I play the same game with > 80 nodes, I start seeing the holes. I *doubt* that it's a bad node, but I'll do some deeper investigating just to verify. -----Original Message----- From: Scott, W Alan [mailto:[email protected]] Sent: Monday, August 26, 2013 3:43 PM To: Angelini, Richard C (Rick) CIV USARMY ARL (US); [email protected] Subject: RE: [EXTERNAL] [Paraview] extract CTH parts (UNCLASSIFIED) Bad node? Try running the problem on a few nodes. Next, try running the "big node" problem. As you shift the nodes you are using, does the issue follow the underlying iron, or the same bad blocks in the dataset? Dataset opens correctly with smaller number of nodes? Want me to try it here? 80 does seem really, really small/easy/trivial for big data...

The dataset consists of 1024 spcth files, regular structured mesh, 14 blocks. The issue seems to be that once I exceed X number of server processes (it seems to be about 80 servers), I start seeing holes in the resulting geometry. The more I exceed the magic number of servers, the more holes I see in the resulting part. If I create a clip using the volume_fraction scalar variable(s), the geometry of the clip is correct - that is, the underlying data seems to be there. So, I'm thinking that the data is being properly distributed and all of the data is accounted for, but that there's an issue with the "extract CTH parts" filter? Doesn't seem likely, but stranger things have happened. Any ideas?
