[petsc-users] Question about dm_view

[Sun, Hui]

A continuing problem: While I was running ./ex5, the output is normal. When I was running ./ex5 -help | grep whatever, the output is still normal. However, when I tried ./ex5 -help | head -20, it output the first 20 lines from help, then it output the some error message. I'm curious why there is such an error message. The error message is pasted below.

MPI_ABORT was invoked on rank 0 in communicator MPI_COMM_WORLD 
with errorcode 59.

NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.
You may or may not see output from other processes, depending on
exactly when Open MPI kills them.

  No, just run the program with the option. For example if there is printed -dm_view_draw <false> then run the program with -dm_view_draw true

I'm testing from my MAC the same commands listed on that page, for example, ex5 -dm_view, nothing interesting happen except the Number of Newton iterations is outputted. I'm expecting that the PETSc numbering would show up as a graphic window or something. Can anyone tell me what's missing here? Thank you!   ( Hui )
