I'm new memeber in this weblog, and I should deliver my assignment as soon as
possible, but I have a big problem that I can't solve it. Please help me. In
MPI I should divide my group into two groups. But all the time when I want to
run a program I got error about mpi_group_incl. This is my erro
Well, one thing immediately leaps to the eye. You compute Neven based on the
number of procs in the job, which you set when executing mpirun. However, the
number of members you put in your group is fixed. Then you pass Neven to the
MPI_Group call as the parameter telling it how many entries are
Further, if Neven is greater than 3, then you've got uninitialized values in
the members array. That could be causing Open MPI to say "there's a bad rank
number in there!", for example, if members[3] is randomly initialized to 1234.

Hi there,
I have attached a little piece of code which summarizes a "bug?" that
annoys me ultimately. Issuing various calls to MPI_WIN_LOCK/UNLOCK seems
to hang some processes until a MPI_BARRIER is encountered!??
My experience with MPI is very modest, so I apologize in advance if I
misread t
I'm so sorry, Actually my problem is in another mpi program which is
"sudoku game". But because of the fact I got inclusion error whenever I
use MPI_Group_incl. For simplicity, I decided to put a simple program
with MPI_Group_incl. Please take a look at the following lines of code,
and please n
