[petsc-users] MPICH error in KSPSolve

[Mark F. Adams]

Google PTL_NO_SPACE and you will find some NERSC presentations on how to go about fixing this.  (I have run into these problems years ago but forget the issues)

Also, I would try running with a Jacobi solver to see if that fixes the problem.  If so then you might try 

-pc_type gamg
-pc_gamg_agg_nsmooths 1
-pc_gamg_type agg

This is a built in AMG solver so perhaps it plays nicer with resources ...
