[petsc-dev] Do you have any suggestion in order to reduce my memory footprint?

[Alletto, John M]

All,

I have a 64 bit linux machine with 256 GByte of memory and 30 processors.
I am solving Laplace equations and the current solver I am using is taking every bit of memory I have available.

Do you have any suggestions (such as changing precision or changing solvers or something else) in order to reduce my memory footprint?

Many Thanks
John
