Hi.
I am having a problem when I try to kill a spawned process. I am using ompi
1.4.3. I use the command ompi-clean to kill all the processes I have
running, but those ones which were dynamically spawned are not killed.
Any idea?
Thanks in advance.
Hi there.
I'm developing a distributed system with a communication layer based on Open
MPI. As part of my project, I have to create a process scheduler. So I
decided to use the MPI_Spawn function to dynamically create (it is an
requirement of the system) the process across the cluster's nodes.
Is
The point is: I have a system composed by a set of mpi processes. These
processes run as daemons in each cluster machine. I need a way to kill
those
ones when I decide to shutdown the system.
Thanks

Hi there.
I am developing a server/client application using Open MPI 1.5.3. In a
point of the server code I open a port to receive connections from a
client. After that, I call the function MPI_Comm_accept and on the
client side I call MPI_Comm_connect. Sometimes I get an
ORTE_ERROR_LOG, as showed
ered by race conditions in the app as well, but ultimately

Hi Ralph. The version you have suggested works properly.
Thank you so much for the attention.

Hi there.
I have an application in which I need to terminate a process anytime due an
external command. In order to maintain the consistence of the processes, I
need to receive the messages that were already sent to the terminating
process. I used the MPI_Iprobe to check whether there is messages
Hi there,
I am facing some problems in an Open MPI application. Part of the
application is composed by a sender and a receiver. The problem is that the
sender is so much faster than the receiver, what causes the receiver's
memory to be completely used, aborting the application.
I would like to kn
Hi
I am still having this problem in my application. Does someone have a
solution or a clue?
Thanks

Hi,
I'd like to know if there is a way to checkpoint a specific process running
under an mpirun call. In other words, is there a function CHECKPOINT(rank)
in which I can pass the rank of the process I want to checkpoint? I do not
want to checkpoint the entire application, but just one of its proce

wrong? According to open mpi documentation, this function can be used to do
that, but it is not working. Anyone have any idea about what can be?

The command I use to compile and run is:
mpic++ server.cc -o server && mpic++ client.cc -o client && mpirun -np 1
./server

Hi Edgar,
Did you take a look at my code? Any idea about what is happening? I did a
lot of tests and it does not work.
Thanks

Hi Edgar.
Thanks for the response. I just did not understand why the Barrier works
before I remove one of the client processes.
I tryed it with 1 server and 3 clients and it worked properly. After I
removed 1 of the clients, it stops working. So, the removal is affecting
the functionality of Barr
a lot for your attention and for the solution.
Best regards,
