vecload_block_size

[(Rebecca) Xuefei YUAN]

Hi,

I am reading from a binary file of the previous solution and would  
like it to be my initial guess.

However, I found that the "-vecload_block_size" is shown in the  
PetscOptionsTable, I did not explicitly state this one in my options  
file, why it shows up in it? And the block size has been assigned as  
"4".

Thanks!

Rebecca


Here is this PetscOptionsTable:
