[OMPI users] ORTE_ERROR_LOG

[Tommi Laiho]

Hi

I am trying to setup a simple two machines home cluster. Later I may increase 
the number to 4 machines. 

I have a bridged modem so each of my machines has its own ip. 

My target is now to calculate a simple OpenFOAM tutorial with two computers and 
together with 14 cores. 

However when I run:

mpirun /opt/openmpi-1.6.5/bin/mpirun -hostfile /home/tommi2/Desktop/machinefile 
-np 14 icofoam cavity -parallel

 I get this kind of error:


[caelinux:31859] [[43391,1],0] ORTE_ERROR_LOG: A message is attempting to be 
sent to a process whose contact information is unknown in file rml_oob_send.c 
at line 104
[caelinux:31859] [[43391,1],0] could not get route to [[INVALID],INVALID]
[caelinux:31859] [[43391,1],0] ORTE_ERROR_LOG: A message is attempting to be 
sent to a process whose contact information is unknown in file 
base/plm_base_proxy.c at line 81

Please tell me what to do in order to fix this and thanks in advance. The 
reason is probably simple cos I am a Linux newbie.

Dear Marco

Once again thank you for kind help. As you suggested, I installed Cygwin,
along with the OpenMPI packages, from the links you sent.

When I run this example (hello.c):

#include 
#include 

int main(int argc, char *argv[]) {
  int numprocs, rank, namelen;
  char processor_name[MPI_MAX_PROCESSOR_NAME];

  MPI_Init(&argc, &argv);
  MPI_Comm_size(MPI_COMM_WORLD, &numprocs);
  MPI_Comm_rank(MPI_COMM_WORLD, &rank);
  MPI_Get_processor_name(processor_name, &namelen);

  printf("Process %d on %s out of %d\n", rank, processor_name, numprocs);

  MPI_Finalize();
}




Now I am getting the following error:


OSMANK@osman /home
$ ls
file1.cc  hello.c  OSMANK

OSMANK@osman /home
$ mpicc hello.c -o hello
hello.c:1:17: *fatal error: mpi.h: No such file or directory*
compilation terminated.

OSMANK@osman /home


I have also tried a c++ version (mpic++) with .cc file and it also gives
the same error. Can you kindly suggest what is wrong here. Do I need to set
any paths? The command such as mpirun or mpicc etc itself does not give
error, but asks for the file inputs.

Thank you in advance.

[OMPI users] Fwd: need help in this error

[Osman Khalid]

Hi Marco,

Kindly ignore my below email, as the problem is solved. Actually, i had
mingw already installed in my system previously, and its path was set in
environment variables. And, the cygwin version I installed didn't have
gcc/g++ packages installed. So, when i was running, mpicc, it was by
default picking the gcc/g++ of mingw. So I removed path of mingw, and
installed packages in cygwin, and now mpicc/mpic++ etc are working. T

Thanks again for your kind help.

I see two "mpirun" cmds on that cmd line - is that a copy/paste error or did 
you really put two of them on one line?

Re: [OMPI users] Get your Open MPI schwag!

[Mike Dubman]

ok, so - here is a final proposal:

front:
small OMPI logo,  under it slogan: OpenMPI - Breaking the Barriers!

back side:

small medum picture of
http://www.deviantart.com/art/chuck-norris-stamp-of-approval-184646710

with text below:

OpenMPI: Leading Parallel Computing Framework, since 2003...


comments?

too modest?

Re: [OMPI users] Get your Open MPI schwag!

[Ralph Castain]

I'm afraid that picture is copyrighted, Mike. While I enjoy the enthusiasm, I 
actually suspect we would get into trouble using Chuck Norris' name without 
first obtaining his permission.

Re: [OMPI users] ORTE_ERROR_LOG

[Tommi Laiho]

Hi.

Yes I really put two mpiruns to the line. A newbie error, many thanks for help. 

But now this seems to work:

/opt/openmpi-1.6.5/bin/mpirun -hostfile /home/tommi2/Desktop/machinefile -np 14 
icofoam cavity -parallel


Anyway now when I try connect with this script to the slave computer it first 
asks for my password and it will be correctly.

Then nothing just happens..maybe the master machine tries to connect to the 
slave machine but connection just cant 
be established. I disabled the firewall just to see if that was the reason but 
it didn't help. 

Any ideas what is still wrong?

Re: [OMPI users] Get your Open MPI schwag!

[Mike Dubman]

i see, it makes sense.

new proposal for back side:

no pictures, just slogan:

If Chuck says you need OpenMPI, you need OpenMPI.

-- certified by Chuck Norris.

 what do you say?

Re: [OMPI users] Get your Open MPI schwag!

[Ralph Castain]

Like I said, if we use his name, we'd first have to get his permission. Just 
"Chuck" is okay as that doesn't identify a specific individual, but his full 
name would require his okay.

Some people are fine with non-profits doing so. Others require compensation, 
which we really don't want to get into.

Re: [OMPI users] ORTE_ERROR_LOG

[Ralph Castain]

I'd suggest reading thru the FAQ on running under ssh

http://www.open-mpi.org/faq/?category=rsh

and perhaps scanning the other FAQ entries in that category.
