Sorry for the delay in replying.
You might want to run your code through a debugger, particularly a
memory-checking debugger. Your stack trace shows that it's segv'ing in main(),
so it might not be that difficult to find.

Hi,
I need to use Open MPI to distribute 2d-array in the PGM file among 10
working computers. Then I need to manipulate each value of the array
to get a negative image (255-i) and then print the output back. I'm
thinking of using mpi_scatterv and mpi_gatherv to distribute the data.

Are you able to run this through valgrind or some other memory-
checking debugger? It looks like the single process case may be the
simplest to check...?

I tried to run a code that I have running for a while now this morning,
but for some reason it is causing segmentation faults. I can't really
think of anything that I have done recently that would be causing these
errors. Does anyone have any idea?
I get this running it on more than one processo
