<br><font size=2 face="sans-serif">Dear PETSc users,</font>
<br>
<br><font size=2 face="sans-serif">We're having difficulties troubleshooting
some developments in our code that relies on PETSc. We're assembling a
matrix of size 90 with the blocksize set to 6, the code is run on two processors
so that processor #0 has 48 entries and #1 has 42 entries.</font>
<br><font size=2 face="sans-serif">During the MatAssemblyEnd, an error
about non conforming object sizes is thrown ("Local scatter sizes
don't match"). This is raised by VecScatterCreate inside MatAssemblyEnd.</font>
<br>
<br><font size=2 face="sans-serif">We're likely doing something wrong but
what would be the way to debug this since the call to VecScatterCreate
is not controlled directly by us ? Attached is the output of '-info' during
the MatAssemblyEnd.</font>
<br>
<br>
<br>
<br><font size=2 face="sans-serif">Note : we're still using PETSc 3.2p7
and have not moved to 3.4.</font>
<br>
<br><font size=2 face="sans-serif">Thanks,</font>
<br>
