It seems that the const variable SOMAXCONN who used by listen() system call
causes this problem. Can anybody help me resolve this question?

Dear all,
As I mentioned, when I mpiruned an application with the parameter "np =
150(or bigger)", the application who used the MPI_Alltoallv function would
carsh. The problem would recur no matter how many nodes we used.
The edition of OpenMPI: 1.4.1 or 1.4.3
The OS: linux redhat 2.6.32

Dear all,
I am doing some tests using MPI_Allgatherv function recently. After these
tests, I found a wield problem of if.
When I wanted to use the MPI_Allgatherv function to gather a large number of
data from some processes(for example, 2GB data per process). If the number
of processes was even n
Dear all,
I have figured it out. It was a simple issue, I didn't add the "blcr lib" to
the $PATH environment varable. However, it can make checkpoint operation,
but can't make restart operation successfully. It was so wield.

Dear all,
I had to try the checkpoint/restart function of Openmpi recently, and after
several failure and checking lots of the docement, I am still very confused
about how to config the checkpoint/restart function. Can anybody give me a
$HOME/.openmpi/mca-params.conf script and introduce me what p
Hi Bowen,
Thanks very much. I had checked my writev system call, I thought it was him
that caused all these bad things :)

Hi Gus Correa
First of all, thanks for your suggestions.
1) The malloc function do return a non_NULL pointer.
2) I didn't tried the MPI_Isend function, actually, The really function I
need to use is MPI_Allgatherv(). When I used it, I found this function
didn't work when the the data >= 2GB, the
Hi
Are you running on two processes (mpiexec -n 2)?
Yes
Have you tried to print Gsize?
Yes, I had checked my codes several times, and I thought the errors came
from the OpenMpi. :)
The command line I used:
"mpirun -hostfile ./Serverlist -np 2 ./test". The "Serverlist" file include
several comput
Openmpi. So, my codes still don't work. :(
Further, I found when I called the collective routines(such as,
MPI_Allgatherv(...)) which are implemented by the Point 2 Point don't work
either when the data > 2GB.
Thanks

hi,
I met a question recently when I tested the MPI_send and MPI_Recv
functions. When I run the following codes, the processes hanged and I
found there was not data transmission in my network at all.
BTW: I finished this test on two X86-64 computers with 16GB memory and
installed Linux.
