Does openmpi mpirun command have the equivalent option "-O" as lam
(homogeneous universe)
I would like avoid automatic byteswap in heterogeneous execution
environment
Thanks in advance

Hi,
Does anybody face problems running Openmpi on two hosts with different
networks (gateway to reach the other) ?
Let say compil02 ip adress is 172.3.9.10 and r009n001 is 10.160.4.1
There is no problem with MPI_init free executables (for example hostname)
compil02% /tmp/HALMPI/openmpi-1.2.2/bin

Actually I dont know exactly , I am asking extra informations to my
network architect
Interesting thing to notice is that LAM work
76348311 20956/orted
unix 3 [ ] STREAM CONNECTED 76348310 20956/orted
I hope it'll help
Does anyone run openmpi program in such environment ???
Thanks again
Geoffroy

Hello
I'm currently trying the new release but I cant reproduce the 1.2.8
behaviour
concerning --wdir option
Then
%% /tmp/openmpi-1.2.8/bin/mpirun -n 1 --wdir /tmp --host r003n030 pwd :
--wdir /scr1 -n 1 --host r003n031 pwd
/scr1
/tmp
but
%% /tmp/openmpi-1.3/bin/mpirun -n

Hello,
As you can notice , I am trying the work done on this new release.
preload-files and preload-binary options are very interesting to me because
I work on a cluster without any shared space between nodes.
I tried those basically , but no success . You will find below the error
messages.
If I
Hello
I redid few tests with my hello world , here are my results.
First of all my config :
configure --prefix=/tmp/openmpi-1.3 --libdir=/tmp/openmpi-1.3/lib64
--enable-heterogeneous . you will find attached my ompi_info -param all all
compil02 and compil03 are identical Rh43 64 bits nodes.

Hi ,
I am currently testing the process affinity capabilities of openmpi and I
would like to know if the rankfile behaviour I will describe below is normal
or not ?
cat hostfile.0
r011n002 slots=4
r011n003 slots=4
cat rankfile.0
rank 0=r011n002 slot=0
rank 1=r011n003 slot=1

Hi,
I am not sure it's a bug but I think we wait for something else when we kill
a proccess - by the way , the signal propagation works well.
I read an explanation on a previous thread - (
http://www.open-mpi.org/community/lists/users/2009/03/8514.php ) . .
It's not important but it could contrib

Hi Lenny,
Here is the basic mpirun command I would like to run :
mpirun -rf rankfile -n 1 -host r001n001 master.x options1 : -n 1 -host
r001n002 master.x options2 : -n 1 -host r001n001 slave.x options3 : -n 1
-host r001n002 slave.x options4
with cat rankfile
rank 0=r001n001 slot=0:*
rank 1=r001
. Any

Ralph, could you tell me if my command syntax is correct or not ? if not,
give me the expected one ?
