Subject: [OMPI users] error from MPI_Allgather
From: Rajesh J (chithrasala_at_[hidden])

Hello,
I have some error while using mpirun. Could anyone please help me solve this.
I googled this and found some, but too technical for me since I am not
so familiar with mpi programs. Is this due to some installation
problem or the program which I run?

Fatal error in PMPI_Allgather: Invalid buffer pointer, error stack:
PMPI_Allgather(958): MPI_Allgather(sbuf=0x6465d30, scount=1,
MPI_INTEGER, rbuf=0x6465d30, rcount=1, MPI_INTEGER, MPI_COMM_WORLD)
failed
PMPI_Allgather(931): Buffers must not be aliased

Thank you very much
