Classification: UNCLASSIFIED Caveats: NONE Alan - yeah, the dataset opens correctly with < 80 servers. 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.

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? Classification: UNCLASSIFIED Caveats: NONE Classification: UNCLASSIFIED Caveats: NONE
