Re: [OMPI users] [Open MPI] #2681: ompi-server publish name broken in 1.5.x
Hello, This feature is very important for my project. It is managing coupling parallel codes. Thanks to correct this bug as soon as possible.

Re: [OMPI users] change between openmpi 1.4.1 and 1.5.1 about MPI2 publish name
The accept and connect tests are OK with version openmpi 1.4.1.
I think there is a bug in version 1.5.1

I get the same dead lock with openmpi tests: pubsub, accept and
connect with version 1.5.1
Bernard Secher - SFME/LGLS a écrit :
Jeff,
The dead lock is not in MPI_Comm_accept and MPI_Comm_connect, but
before in MPI_Publish_name and MPI_Lookup_name.
So the broadcast of srv is not involved in the dead lock.

Only the processes of the program where process 0 successed to
publish name, have srv=1 and then call MPI_Comm_accept.
The processes of the program where process 0 failed to publish name,
have srv=0 and then call MPI_Comm_connect.
That's worked like this with openmpi 1.4.1.
Is it different whith openmpi 1.5.1 ?

[OMPI users] [SPAM:### 85%] Re: [SPAM:### 83%] problem when compiling ompenmpiV1.5.1
Thanks Jody,
Is it possible to install openmpi without openmp ? Is there any option
in configure for that ?
Bernard
jody a écrit :
Hi
if i rememmber correctly, "omp.h" is a header file for OpenMP which is
not the same as Open MPI.
So it looks like you have to install OpenMP,
Then you can compile it with the compiler option -fopenmp (in gcc)

Re: [OMPI users] dead lock in MPI_Finalize
Hi Jody,
I think it is not a problem of MPI_Sends which doesn't match a
corresponding MPI_Recvs, because all processes reach MPI_Finalize(). If
not, at least one process would be blocked before reaching MPI_Finalize.

So are you sure all processes reach the MPI_Finalize command?
Usually MPI_Finalize only completes when all processes reach it.
I think you should also make sure that all MPI_Sends are matched by
corresponding MPI_Recvs.

Re: [OMPI users] dead lock in MPI_Finalize
Hello George,
Thanks for your messages. Yes i disconnect my different worlds before
calling MPI_Finalize().

George Bosilca a écrit :
I was somehow confused when I wrote my last email and I mixed up the
MPI versions (thanks to Dick Treumann for gently pointing me to the
truth). Before MPI 2.1, the MPI Standard was unclear how the
MPI_Finalize should behave in the context of spawned or joined worlds,
which make the disconnect+finalize the only safe and portable way to
correctly finalize all processes connected. However, the MPI 2.1 had
clarified this point, and now MPI_Finalize is collective over all
connected processes (for a definition of connected processes please
see the MPI 2.1 10.5 page 318).
However, if you really want to write a portable MPI application, I
suggest to use the disconnect+finalize, at least until all MPI
libraries available are 2.1 compliant.
Open MPI 1.3 version was supposed to be 2.1 compliant, so I guess I'll
have to create a new bug report for this.
Thanks,
george.

[OMPI users] default hostfile with 1.3 version
Hello, I take 1.3 version from svn base. The default hostfile in etc/openmpi-default-hostfile is not taken. I must give to mpirun the -hostfile option to take this file. Is there any change in 1.3 version? Regards Bernard
Re: [OMPI users] using of MPI_Publish_name with openmpi
I have the same pb with 1.2.9rc1 version.
I don't see any orte-clean utility in this version.
But the best is i use the 1.3 version. Thanks to give me more details
about ompi-server in the 1.3 version.
Regards
Bernard

Bernard,
Could you give us more details on the version of Open MPI you are
using ? I suppose from your message this is one of the 1.2 series,
but mode details would be greatly helpful.
An utility called orte-clean can be used to try to remove all the
garbage left, should something go wrong.
We have fixed a number of bugs in the MPI-2 dynamics recently. The
forthcoming 1.3 should be more robust to that aspect. You can have a
preview of it by using the svn version of Open MPI. The concepts have
changed a little since then as --persistent --seed have been replaced
by an external name server called ompi-server. I can give you more
details if you want to try the svn version.
Regards,
Aurelien

Hi everybody
I want to use MPI_publish_name function to do communicaztion between
two independant code.
I saw on the web i must use the orted daemon with the following
command:
orted --persistent --seed --scope public --universe foo
The communication success, but when i close the communication I
have a dead-lock at the following function: MPI_Comm_disconnect();
I have a second question:
How can i stop the orted daemon?
Bernard
