Ando,
I do not see any error message from attached info below.
Even '-log_summary' gives correct display.
I guess you sent us the working output (np=2).
I have attached 3 files. The one you found with -log_summary printed is indeed
the working scenario.
The other 2

Hi,

It seems the code hangs in MatView_MPISBAIJ_ASCIIorDraworSocket (), a
not well-tested routine.
Can you send us your matrix in petsc binary format?
We can test it and find a fix.
My understanding is: when given the option -ksp_view_binary
on np=4, the code hangs.
What happens without the option
You have to remove the defines or rename them to something else in
petscconf.h. Just commenting or undefining doesn't work. [this is
because our build system does a grep on this file - so its doesn't
exactly follow preprocessing directives]
Regarding the original issue - I'm not sure why it
