Hello everyone, I am using PetscPrintf(PETSC_COMM_WORLD,.....) to print out some information. When I run the program on multiple processors, some of these calls are printed out multiple times, while other calls are printed out once. Should it be printed only once if I use PETSC_COMM_WORLD? Thanks.
Xiangdong PS. I am using petsc-dev. My code works fine on real petsc-3.1-p8. I just switched to complex petsc-dev and see this problem.
