If you expect data of 160 bytes you have to allocate a buffer

If you want to receive data in chunks, you have to send it in chunks.

I've got a really strange problem:
I've got an application which creates intercommunicators between a

When i run it on our cluster with 11 processes it works,
when i run it with 12 processes it hangs inside MPI_Intercomm_create().
This is the hostfile:

Just to make sure: usually the MPI_ERR_TUNCATE error is caused by

Usually MPI_ERR_TRUNCATE means that the buffer you use in MPI_Recv

Hi Brian
When you spawn processes with MPI_Comm_spawn(), one of the arguments
will be set to an intercommunicator of thes spawner and the spawnees.
You can use this intercommunicator as the communicator argument

Does anybody know how to get replace the old man files with the new ones?

Hi Ralph
I finally got around to install version 1.4.
The xterm works fine.
And in order to get gdb going on the spawned processes, i need to add
an argument "--args"
in the argument list of the spawner so that the parameters of the
spawned processes are getting through gdb.
Thanks ag

applied to the dynamically spawned procs too"
Does this passing on also apply to the -x options?
Thanks

Thanks for your reply
That sounds good. I have Open-MPI version 1.3.2, and mpirun seems not
to recognize the --xterm option.
[jody@plankton tileopt]$ mpirun --xterm -np 1 ./boss 9 sample.tlf
--
mpirun was unable to launch the
environment variable in order to
display their xterms with gdb on my workstation.
Another negative point would be the need to change the argv parameters
every time one switches between debugging and normal running.
Has anybody got some hints on how to debug spawned processes?
Thank You
Jody
int you to an MPI primer or tute.

Have a look at the Open MPI FAQ:
http://www.open-mpi.org/faq/?category=running
It shows you how to run a Open-MPI program on single or multiple machines

Sorry, i can't help you here.
I have no experience with neither intel compilers nor IB

Hi
Just curious:
Is there a particular reason why you want version 1.2?
The current version is 1.3.3!

that is where i put the application.
To start your application, follow the instructions in the FAQ:
http://www.open-mpi.org/faq/?category=running
If you want to use host files, read about how to use them in the FAQ:
http://www.open-mpi.org/faq/?category=running#mpirun-host
Hope that helps

Hi
Have look at the Open MPI FAQ:
http://www.open-mpi.org/faq/
It gives you all the information you need to start working with your cluster.

Did you also change the "&buffer" to buffer in your MPI_Send call?

Hi
I'm not sure if i completely understand your requirements,
but have you tried MPI_WTime?

But something is wrong with dyld anyhow.

ets linked with /usr/lib/libmpi...
Note, that the /opt/openmpi/bin path is properly set and ompi_info
does outputs the right info.
You do not need to set DYLD_LIBRARY_PATH. I don't have it set and my
mpi applications run fine.
Did 4 work?
Cheers, Jody

Hi
I had a similar problem.
Following a suggestion from Lenny,
i removed the "max-slots" entries from
my hostsfile and it worked.
It seems that there still are some minor bugs in the rankfile mechanism.
See the post
http://www.open-mpi.org/community/lists/users/2009/08/10384.php
Jod
-mpi.org/faq/?category=running#mpirun-scheduling
but i couldn't find any explanation. (furthermore, in the FAQ it says
"max-slots"
in one place, but "max_slots" in the other one)
Thank You
Jody

However, I encountered a new problem:
if the rankfile lists all the entries which occur in the host file
there is an error message.
In the following example, the hostfile is
[jody@plankton neander]$ cat th_02
nano_00.uzh.ch slots=2 ma
