Hi Alessandro,

It is very hard to think about the reason for your problem without any code. Can you send us your test code and the version of MPICH you are using?

Thanks,

Dear all,

I'm having the following error:

Fatal error in MPI_Get: Internal MPI error!, error stack:
MPI_Get(156).......: MPI_Get(origin_addr=0x19a5f40, origin_count=4,
MPI_BYTE, target_rank=0, target_disp=0, target_count=4, MPI_BYTE,
win=0xa0000000) failed
MPIDI_Get(247).....:
MPIR_Localcopy(357): memcpy arguments alias each other, dst=0x19a5f40
src=0x19a5f40 len=4

if I try to execute MPI_Get on the same memory location on a shared
memory machine (my laptop).

I cannot find anything in the standard that denies it for the one-sided.

Running with OpenMPI everything works fine.

Is it a bug or I missed something in the standard?

Thanks.

Alessandro
