MPI_Bcast error

[Aram_D_1]

Hello,

I run into the following error when running a MPI program. It happens when I run the following line with n_data2 defined as int.

MPI_Bcast(&n_data2, 1, MPI_INT, 0, MPI_COMM_WORLD);

[cli_15]: aborting job:
Fatal error in PMPI_Bcast:

Hi Aram, This is not the appropriate sub-forum to ask this question. You may want to ask it in Intel MPI Library sub-forum or compiler sub-forum. Sorry that I'm unable to move your thread to either of the forums. Thanks.
