Dear All: I am using /petsc-3.3-p6/src/ksp/ksp/examples/tutorials/ex10.c.html as the driver to calculate a Ax=b system. In the job submit line, I am using: ./ex10 -f input.petsc.bin -ksp_type bcgs -ksp_rtol 1.e-5 -ksp_max_it 40000 -ksp_monitor -table
Then I got the error message: [0]PETSC ERROR: No support for this operation for this object type! [0]PETSC ERROR: Viewer type string not supported for KSP cg! Looks bcgs is not compatible with -table option. Because in ex10.c mentioned above, -table has viewer operations. And I used cg and cr, both work. ./ex10 -f input.petsc.bin -ksp_type cg -ksp_rtol 1.e-5 -ksp_max_it 40000 -ksp_monitor -table ./ex10 -f input.petsc.bin -ksp_type cr -ksp_rtol 1.e-5 -ksp_max_it 40000 -ksp_monitor -table So, How could I get the iteration time and other information for bcgs option? Thanks Qiyue Lu
