[mpich-discuss] How to use MPI_IN_PLACE properly in MPI::COMM_WORLD.Gatherv?

Sun May 27 07:15:17 CDT 2012

Hi Jeff,

As Rajeev said I used MPI_IN_PLACE instead of senbuf, still I am not able
to get the things right.
Thats why I posted my used code and error.

I am using :
MPI::COMM_WORLD.Gatherv(MPI_IN_PLACE, Count[rank], MPI::CHAR,
(void*)(Data), Count, Displ, MPI::CHAR, 0);

instead of my previous code:
//MPI::COMM_WORLD.Gatherv((const void*)(Data+StartFrom[nStages-1][rank]),
Count[rank], MPI::CHAR, (void*)(Data), Count, Displ, MPI::CHAR, 0);

and still getting the error. What wrong I am doing?

Thanks...
