Can you set a different prefix for each vector? (I'm surprised that more people don't run into this problem of incompatibility, but don't know an easy generic way to fix the problem.)<div><br></div><div><div>$ cat <a href="http://vector.dat.info">vector.dat.info</a> </div>

<br>
I think I found another bug related to Vec blocksize...<br>
<br>
It looks like loading vectors with different block sizes from a binary fine is broken in petsc-3.3:<br>
try the attached example:<br>
<br>
iMac:Misc blaise$ ./TestVecLoad-dev -ndofU 1 -ndofV 3 -nx 2 -ny 2 -mode 0<br>
