[OMPI users] error durgin execution

[Luis Vitorio Cargnini]

Hi,
Please someone could help me with this error:
[node11][0,1,7][/SourceCache/openmpi/openmpi-5/openmpi/ompi/mca/btl/ 
tcp/btl_tcp_frag.c:202:mca_btl_tcp_frag_recv] mca_btl_tcp_frag_recv:

Any idea of what this can be ? and how to solve it ? and how to avoid  
this ?

Re: [OMPI users] ompi_info segmentation fault with Snow Leopard

[Luis Vitorio Cargnini]

Did you try using the Apple compiler too ?

Hi,
I am trying to install openmpi 1.3.3 under OSX 10.6 (Snow Leopard)  
using the 11.1.058 intel compilers. Configure and build seem to work  
fine. However trying to run ompi_info after install causes directly  
a segmentation fault without any additional information being printed.

Did anyone have success in using 1.3.3 under Snow Leopard?

Thanks

Re: [OMPI users] Xgrid and choosing agents...

[Luis Vitorio Cargnini]

did you saw that, maybe, just maybe using:
xserve01.local slots=8 max-slots=8
xserve02.local slots=8 max-slots=8
xserve03.local slots=8 max-slots=8
xserve04.local slots=8 max-slots=8

it can set the number of process specifically for each node, the  
"slots" does this setting the configuration of slots per each node,  
try it with the old conf of Xgrid and also test with your new Xgrid  
conf.

If anyone else is using xgrid, there is a mechanism to limit the  
processes per machine:


sudo defaults write /Library/Preferences/com.apple.xgrid.agent  
MaximumTaskCount 8


on each of the nodes and then restarting xgrid tells the controller  
to only send 8 processes to that node.  For now that is fine  
solution for my need.  I'll try and figure out how to specify hosts  
via xgrid and get back to the list...


Thanks for everyone's help,

For now, though, if you add --bynode to your command line, you  
should get the layout you want. I'm not sure you'll get the rank

Hi Vitorio,

Thanks for getting back to me!  My hostfile is

xserve01.local max-slots=8
xserve02.local max-slots=8
xserve03.local max-slots=8
xserve04.local max-slots=8

I've now checked, and this seems to work fine just using ssh.   
i.e. if I turn off the Xgrid queue manager I can submit jobs  
manually to the appropriate nodes using --hosts.


However, I'd really like to use Xgrid as my queue manager as it is  
already set up (though I'll happily take hints on how to set up  
other queue managers on an OS X cluster).


So you have 4 nodes each one with 2 processors, each processor 4- 
core - quad-core.

So you have capacity for 32 process in parallel.


The new Xeon chips designate 2-processes per core, though at a  
reduced clock rate.  This means that Xgrid believes I have 16  
processors/node.  For large jobs I expect that to be useful, but  
for my more modest jobs I really only want 8 processes/node.


It appears that the default way xgrid assigns the jobs is to fill  
all 16 slots on one node before moving to the next.  OpenMPI  
doesn't appear to look at the hostfile configuration when using  
Xgrid, so it makes it hard for me to deprecate this behaviour.


Thanks,  Jody



I think that only using the hostfile is enough is how I use. If  
you to specify a specific host or a different sequence, the  
mpirun will obey the host sequence in your hostfile to start the  
process, also can you put how you configured your host files ?  
I'm asking this because you should have something like:

# This is an example hostfile. Comments begin with
# #
# The following node is a single processor machine:
foo.example.com
# The following node is a dual-processor machine:
bar.example.com slots=2
# The following node is a quad-processor machine, and we absolutely
# want to disallow over-subscribing it:
yow.example.com slots=4 max-slots=4
so in your case like mine you should have something like:
your.hostname.domain slots=8 max-slots=8 # for each node

I hope this will help you.

I'm using openMPI on 4  duo Quad-core Xeon xserves.  The 8 cores  
mimic 16 cores and show up in xgrid as each agent having 16

Unfortunately, if I submit a 16-processor job to xgrid it all

I tried making a hostfile and then specifying the host, but I get:

/usr/local/openmpi/bin/mpirun -n 8 --hostfile hostfile --host  
xserve01.local ../build/mitgcmuv


Some of the requested hosts are not included in the current

../build/mitgcmuv
The requested hosts were:
xserve01.local

so I assume --host doesn't work with xgrid?

Is a reasonable alternative to simply not use xgrid and rely on  
ssh?

Re: [OMPI users] MPI and C++ (Boost)

[Luis Vitorio Cargnini]

Ok, after all the considerations, I'll try Boost, today, make some  
experiments and see if I can use it or if I'll avoid it yet.


But as said by Raimond I think, the problem is been dependent of a  
rich-incredible-amazing-toolset  but still implementing only  
MPI-1, and do not implement all the MPI functions main drawbacks of  
boost, but the set of functions implemented do not compromise the  
functionality, i don't know about the MPI-1, MPI-2 and future MPI-3  
specifications, how this specifications implementations affect boost  
and the developer using Boost, with OpenMPI of course.


Continuing if something change in the boost how can I guarantee it  
won't affect my code in the future ? It is impossible.


Anyway I'll test it today and without it and choose my direction,  
thanks for all the replies, suggestions, solutions, that you all  
pointed to me I really appreciate all your help and comments about  
boost or not my code.


Thanks and Regards.
Vitorio.

I think you face a common trade-off:

- use a well-established, debugged, abstraction-rich library
- write all of that stuff yourself

FWIW, I think the first one is a no-brainer.  There's a reason they  
wrote Boost.MPI: it's complex, difficult stuff, and is perfect as  
middleware for others to use.


If having users perform a 2nd step is undesirable (i.e., install  
Boost before installing your software), how about embedding Boost in  
your software?  Your configure/build process can certainly be  
tailored to include Boost[.MPI].  Hence, users will only perform 1  
step, but it actually performs "2" steps under the covers (configures 
+installs Boost.MPI and then configures+installs your software,  
which uses Boost).


FWIW: Open MPI does exactly this.  Open MPI embeds at least 5  
software packages: PLPA, VampirTrace, ROMIO, libltdl, and libevent.   
But 99.9% of our users don't know/care because it's all hidden in  
our configure / make process.  If you watch carefully, you can see  
the output go by from each of those configure sections when running  
OMPI's configure.  But no one does.  ;-)


Sidenote: I would echo that the Forum is not considering including  
Boost.MPI at all.  Indeed, as mentioned in different threads, the  
Forum has already voted once to deprecate the MPI C++ bindings,  
partly *because* of Boost.  Boost.MPI has shown that the C++  
community is better at making C++ APIs for MPI than the Forum is.   
Hence, our role should be to make the base building blocks and let  
the language experts make their own preferred tools.

Hi,

At the moment, I think that Boost.MPI only supports MPI1.1, and even
then, some additional work may be done, at least regarding the  
complex

datatypes.

Hi Raymond, thanks for your answer
Le 09-07-06 à 21:16, Raymond Wan a écrit :


I've used Boost MPI before and it really isn't that bad and  
shouldn't be seen as "just another library".  Many parts of Boost  
are on their way to being part of the standard and are discussed and  
debated on.  And so, it isn't the same as going to some random  
person's web page and downloading their library/template. Of course,  
it takes time to make it into the standard and I'm not entirely sure  
if everything will (probably not).


(One "annoying" thing about Boost MPI is that you have to compile  
it...if you are distributing your code, end-users might find that  
bothersome...oh, and serialization as well.)




we have a common factor, I'm not exactly distributing, but I'll add a  
dependency into my code, something that bothers me.


One suggestion might be to make use of Boost and once you got your  
code working,  start changing it back.  At least you will have a  
working program to compare against.  Kind of like writing a  
prototype first...




Your suggestion is a great and interesting idea. I only have the fear  
to get used to the Boost and could not get rid of Boost anymore,  
because one thing is sure the abstraction added by Boost is  
impressive, it turn the things much less painful like MPI to be  
implemented using C++, also the serialization inside Boost::MPI  
already made by Boost to use MPI is astonishing attractive, and of  
course the possibility to add new types like classes to be able to  
send objects through MPI_Send of Boost, this is certainly attractive,  
but again I do not want to get dependent of a library as I said, this  
is my major concern.

Thanks, but I really do not want to use Boost.
Is easier ? certainly is, but I want to make it using only MPI itself  
and not been dependent of a Library, or templates like the majority of  
boost a huge set of templates and wrappers for different libraries,  
implemented in C, supplying a wrapper for C++.
I admit Boost is a valuable tool, but in my case, as much independent  
I could be from additional libs, better.

I strongly suggest you take a look at boost::mpi, 
http://www.boost.org/doc/libs/1_39_0/doc/html/mpi.html

It handles serialization transparently and has some great natural  
extensions to the MPI C interface for C++, e.g.


bool global = all_reduce(comm, local, logical_and());

This sets "global" to "local_0 && local_1 && ... && local_N-1"

Vitorio,

If you are sending collections of built in data types (ints,  
doubles, that sort of thing), then it may be easy, and it isn't  
awful. You want the data in a single stretch of continuous memory.  
If you are using an STL vector, this is already true. If you are  
using some other container, then no guarantees are provided for  
whether the memory is continuous.


Imagine you are using a vector, and you know the number of entries  
in that vector. You want to send that vector to processor 2 on the  
world communicator with tag 0. Then, the code snippet would be;


std::vector v;

... code that fills v with something ...

int send_error;

send_error = MPI_Send([0], v.size(), MPI_DOUBLE, 2,  
0,  MPI_COMM_WORLD);


The [0] part provides a pointer to the first member of the array  
that holds the data for the vector. If you know how long it will  
be, you could use that constant instead of using the v.size()  
function. Knowing the length also simplifies the send, since the  
remote process also knows the length and doesn't need a separate  
send to provide that information.


It is also possible to provide a pointer to the start of storage  
for the character array that makes up a string. Both of these  
legacy friendly interfaces are part of the standard, and should be  
available on any reasonable implementation of the STL.


If you are using a container that is not held in continuous  
memory, and the data is all of a single built in data type, then  
you need to first serialize the data into a block of continuous  
memory before sending it. (If the data block is large, then you  
may actually have to divide it into pieces and send them  
separately.)


If the data is not a block of all a single built in type, (It may  
include several built in types, or it may be a custom data class  
with complex internal structure, for example.) then the  
serialization problem gets harder. In this case, look at the MPI  
provided facilities for dealing with complex data types and  
compare to the boost provided facilities. There is an initial  
learning curve for the boost facilities, but in the long run it  
may provide a substantial development time savings if you need to  
transmit and receive several complex types. In most cases, the run  
time cost is small for using the boost facilities. (according to  
the tests run during library development and documented with the  
library)

Thanks for your answers I'll use normal C-style MPI so. I checked  
boost, but it seems it only supplies me with a shared communication  
interface among the nodes, turning a little difficult to parallelize  
the processes itself, also boost obligate me to have an MPI  
installation too. Boost is working like a giant wrapper for many non-

additional things.

the code directory is nfs shared and mounted on the client system

the server system is 10.0.3.1

i can ping the client from server and also server from client. ssh  
is working bothways.


the /etc/openmpi/openmpi-default-hostfile is having the line on the  
first node ie. 10.0.3.1


10.0.3.3 slots=2


the other nodes file is just empty. i mean only comments are there.


this is the error is get when i execute.

now, when i remove that line from /etc/openmpi/openmpi-default- 
hostfile on the first node


the program compiles and executes on the first node node.

same, when i compile it and execute it on the second node, it works.

only problem is when i try to run it on both.

i get the error mesage as above.


someone, please help me. as i am trying to setup this system for the  
first time.


and i am stuck.

i am fairly good with linux. so i know my way around linux. but am  
stuck with open mpi.

Re: [OMPI users] How do I compile OpenMPI in Xcode 3.1

[Luis Vitorio Cargnini]

This problem is occuring because the fortran wasn't compiled with the  
debug symbols:
warning: Could not find object file "/Users/admin/build/i386-apple- 
darwin9.0.0/libgcc/_udiv_w_sdiv_s.o" - no debug information available  
for "../../../gcc-4.3-20071026/libgcc/../gcc/libgcc2.c".


Is the same problem for who is using LLVM in Xcode, there is no debug  
symbols to create a debug release, try create a release and see if it  
will compile at all and try the fortran from macports it will works  
smoothly.

I get those as well.  I believe that they are (annoying but)

There is no 'admin' so I don't know why it happen. It works well

I can run openmpi perfectly with command line, but I wanted a

Thanks anyway.

Admittedly, I don't use Xcode to build Open MPI either.

You can just compile Open MPI from the command line and install  
everything in /usr/local/. Make sure that gfortran is set in your  
path and you should just be able to do a './configure --prefix=/usr/ 
local'


After the installation, just make sure that your path is set  
correctly when you go to use the newly installed Open MPI. If you  
don't set your path, it will always default to using the version of  
OpenMPI that ships with Leopard.

Open MPI comes pre-installed in Leopard; as Warner noted, since  
Leopard
doesn't ship with a Fortran compiler, the Open MPI that Apple ships  
has

non-functional mpif77 and mpif90 wrapper compilers.
