The ticket you point out in your test program (<a href="https://trac.mcs.anl.gov/projects/mpich2/ticket/1028" target="_blank">https://trac.mcs.anl.gov/projects/mpich2/ticket/1028</a>) has been fixed in r6426 as mentioned on the ticket. Did you try the nightly snapshots (<a href="http://www.mcs.anl.gov/research/projects/mpich2/downloads/tarballs/nightly/trunk" target="_blank">http://www.mcs.anl.gov/research/projects/mpich2/downloads/tarballs/nightly/trunk</a>)? If not, can you try them out and see if you are still seeing this problem?<br>
<br>
Thanks,<br>

Hello,<br>
<br>
<br>
MPICH2's predefined reduce operation seems it can not support<br>
quadruple precision.<br>
<br>
<br>
I used the attached program to test this. And got the following<br>
error message,<br>
<br>
Fatal error in PMPI_Reduce: Invalid MPI_Op, error stack:<br>
PMPI_Reduce(1198).......: MPI_Reduce(sbuf=0012FF00, rbuf=0012FF10, count=1, dtyp<br>
e=0x4c00102b, MPI_SUM, root=0, MPI_COMM_WORLD) failed<br>
MPIR_SUM_check_dtype(97): MPI_Op MPI_SUM operation not defined for this datatype<br>
<br>
<br>
If so, is there any plan to support this ?<br>
<br>
<br>
Thank you.<br>
<br>
<br>
<br>
YIN<br>
