<div>Hi Alessandro,</div>
<div><br>
</div>
<div>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?</div>
<div><br>
</div>
<div>Thanks,</div>

<br>
I'm having the following error:<br>
<br>
Fatal error in MPI_Get: Internal MPI error!, error stack:<br>
MPI_Get(156).......: MPI_Get(origin_addr=0x19a5f40, origin_count=4,<br>
MPI_BYTE, target_rank=0, target_disp=0, target_count=4, MPI_BYTE,<br>
win=0xa0000000) failed<br>

MPIR_Localcopy(357): memcpy arguments alias each other, dst=0x19a5f40<br>
src=0x19a5f40 len=4<br>
<br>
if I try to execute MPI_Get on the same memory location on a shared<br>
memory machine (my laptop).<br>
<br>
I cannot find anything in the standard that denies it for the one-sided.<br>
<br>
Running with OpenMPI everything works fine.<br>
<br>
Is it a bug or I missed something in the standard?<br>
<br>
Thanks.<br>
<br>
