Hi Joseph,<br>
<br>
Thanks for reporting this issue and the reproducer program. I just
confirmed this is a bug in MPICH request-based RMA routine. I will
fix it soon and add your reproducer into our test suite.<br>
<br>
You can check the status through the ticket:

Thanks,<br>

I am running into a problem with MPI_Rget in combination with
MPI_Testall, where the call to MPI_Testall fails with the error
hinting at more information in the status' MPI_ERROR fields.
However, these fields only signal success:
<br>
<br>
[0] MPI_Testall failed:
<br>
See the MPI_ERROR field in MPI_Status for the error code (17)
<br>
[0] Request error: No MPI error (0)
<br>
[0] Request error: No MPI error (0)
<br>
<br>
I am attaching a small reproducer. I should note that the
application succeeds if I am using MPI_Test on the individual
requests instead of MPI_Testall.
<br>
<br>
Please let me know if my usage of MPI_Rget and MPI_Testall is
erroneous for some reason. I can reproduce this error with both
MPICH 3.2 and 3.2.1 as well as Intel MPI 2017 even when running
with a single process.
<br>
<br>
Many thanks in advance,
<br>
Joseph
