Re: disk space requirement for mpich2 during PETSc library compilation

Thanks Barry & Aron.

 

I've tried to install mpich2 on a scratch directory and it finished in a short while.

Ben,

This is partially our fault. We never run "make clean" on MPICH after the
install so there are lots of .o and .a files lying around. I've updated
BuildSystem/config/packages/MPI.py to run make clean after the install.
