[petsc-users] PetscTableCreateHashSize

[Kong, Fande]

Hi All,

Hash size is set manually according to the number of expected keys in the
function PetscTableCreateHashSize(). Any reason to restrict the
``n"<3276800?

One user here encountered an issue because of this restriction. The
messages are as follows:

[3]PETSC ERROR: --------------------- Error Message
