<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">Hi Rajeev,<br>
You can use mbsize -p0 option<br>
This will load the file in parallel, but the printout will be mangled between processors, each processor will write its count (-p1 will resolve shared entities, too), -p2 will exchange a layer of ghost elements)<br>
<br>
so you can do something like this<br>
mpiexec -np 64 mbsize -p0 <file_name><br>
<br>
How many partitions do you have?<br>
<br>
Do you have partitions? (parallel partitions?)<br>
<br>
You can also modify HelloParMOAB example for you needs (harder)<br>
<br>
LoadPartial example can load only a few partitions, and write a smaller file, it can be run in serial<br>
<br>
Something like<br>
./LoadPartial <file_name> PARALLEL_PARTITION 0 1 5<br>
<br>
This will load only partitions 0, 1 and 5, in serial, and write a part.h5m file, for which you can do an mbsize in serial (if it is small enough)<br>
<br>
All these methods will ensure at least that you have a "readable" file .<br>
<br>
I think we need to modify mbsize to run better in parallel (for example, to gather all counts from each processor, for the owned entities) and print only once , something like HelloParMOAB<br>
