most of those extra sets are the shared sets between parts.<br>
also, there are some sets that comprise all entities on a task<br>
<br>
some of them are used during ghosting<br>
<br>
You should have all the original sets, too.<br>
<br>
If it becomes a problem for you, please raise an issue on bitbucket, and we may offer an option to not write them<br>
(maybe there is one now, but I do not know it)<br>

Subject: [MOAB-dev] Parallel output writes odd sets<br>
<br>
Hello MOAB-dev,<br>
<br>
I have a simple program that reads then writes h5m file in parallel<br>
The input file is brick1x1x2p2.h5m<br>
The output file is out.h5m<br>
<br>
Output of mbsize -ll brick1x1x2p2.h5m shows there're 29 EntitySets : 1-27 are geometry sets, 28 and 29 are partition sets made by mbpart<br>
<br>
I run my program in parallel : mpiexec.mpich2 -n 2 ./restart brick1x1x2p2.h5m<br>
Output of mbsize -ll out.h5m shows there're 33 EntitySets<br>
<br>
Loading another larger mesh prepartitioned for 16 processors, there're +4 sets when running on 2 cores, +16 when running on 4 cores, +120 sets when running on 16 cores<br>
(after removing PARALLEL_RESOLVE_SHARED_ENTS option for load_file, there's +97 set for 16 processors)<br>
<br>
What are those extra EntitySets?<br>
<br>
cpp code + h5m file attached<br>
<br>
Thanks<br>
Anton<br>
