You have to change the options of default solver, either adding the fowolling lines to a file mypetsc.par: 

-ksp type cg
-pc_type icc

and then 
getdp myfile.pro -solve myresolution -solver mypetsc.par

or direct from the command line
getdp myfile.pro -solve myresolution -ksp_type cg -pc_type icc

You can have a look to petsc manual for getting all the possibilities:
