George,
Thanks for your reply.
Yes, as you explained, a case specifying an inactive request for MPI_Test
is OK. But the problem is a case specifying an inactive request for
MPI_Wait, MPI_Waitall, and MPI_Testall, as I explained in my first mail.
See code below:
/* make a inactive reques
Takahiro,
I fail to see the cases your patch addresses. I recognize I did not have the
time to look over all the instances where we deal with persistent inactive
requests, but at the first occurrence, the one in req_test.c line 68, the case
you exhibit there is already covered by the test "requ

Hi Santhosh,

Hi All,
I am having a strange problem with the floating precision. I get correct
precision when I launch with one process, but when the same code is launched
with 2 or more process I am losing precision in MPI_Redcue(..., MPI_FLOAT,
MPI_SUM..); call. Output from my code

Hi Open MPI developers,
How is my updated patch?
If there is an another concern, I'll try to update it.

Dear Sir or Madam,
I'm running application on SMP clusters and want to get good performance
for collective communications utilizing shared memory feature. I browse
official website of OpenMPI, and see that OpenMPI can automatically find
the best network according to the hardware architecture, for
