Hi, I was trying to compile and run the example file $PETSC_DIR/src/ksp/pc/examples/tutorials/ex3.c, which demonstrates PETSc's preconditioned conjugate gradient solver for a system of linear equations. After compiling, running make runex3 is supposed to throw up the error "Divergence because of indefinite preconditioner" and running make runex3_pd is supposed to work and give the correct solution. But instead I get the error "Other kind of divergence: this should not happen." for the latter. Is there some bug in the code, or are there any other options that need to be set?
Thanks, Anush -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.mcs.anl.gov/pipermail/petsc-dev/attachments/20100823/5e4dbb68/attachment.html>
