Re: [OMPI users] Using OpenMPI on a network

[Shiqing Fan]

Hi,

I also noticed this problem (see my reply in the original thread). It 
seems that since 1.6, the etc/openmpmi-default-hostfile is checked by 
ORTE before running the application. But previous versions on Windows 
don't have such problem. But anyway, copying over or creating the empty 
file will solve the problem. The fix is already moved into 1.6 branch.

I uninstalled everything to do with MPI, Cygwin, cleared environment

supercomputing tutorial.

There's something else wrong, if that's the Supercomputing Blog 
tutorial 1 you're running.  It works happily without a hostfile.  I 
think you have some borked paths there.


I don't know why a Windows version is looking for an etc directory for 
a hostfile, unless there's some of your previous Cygwin builds lying 
around.  The etc directory is *Nix thing.  Please make sure you've 
completely deleted all your old failed OpenMPI builds, code, binaries, 
everything. Uninstall any other MPI versions you have tried, OpenMPI, 
MPICH, whatever.  You need to make absolutely sure you only have one 
version.  Check your paths in your environment after doing all that 
and remove any remaining path references to other MPI versions.  You 
shouldn't be getting that network error either, if you're running 
locally it won't matter if you have a network cable or not.  That has 
to be fixed before you can do anything on a cluster.

Re: [OMPI users] Using OpenMPI on a network

[Shiqing Fan]

Hi,

This was a bug due to the late release of Windows installers. You can 
simply copy the file from 
/openmpi-source/orte/etc/openmpi-default-hostfile to 
C:\OpenMPI\openmpi-1.6\installed\etc\. This problem only happens when 
you build from the released source, but not with the Windows installers.

If you still have the other OpenMPIs installed from the binaries, you

helloworldMPI is actually linked to those VS2010 OpenMPI libs by

You're getting that error because you failed to specify any hosts on
your cmd line - so OMPI has no idea where to launch the procs. It looked
for a default hostfile, but didn't find that either.

 

Just add a -host  option to your command line and tell it
where you want the procs to run.

[Ralph Castain]

You're getting that error because you failed to specify any hosts on your cmd 
line - so OMPI has no idea where to launch the procs. It looked for a default 
hostfile, but didn't find that either.

Just add a -host  option to your command line and tell it where you 
want the procs to run.

So I configured and compiled a simple MPI program.

OK, that's what orte_rml_base_select failed means, no TCP connection.  But you 
should be able to make OpenMPI & mpiexec work without a network if you're just 
running in local memory.  There's probably a runtime parameter to set but I 
don't know what it is.  Maybe Jeff or Shiqing can weigh in with what that is.

Hmmm.  Two things.  Can you run helloworldMPI.exe on it's own?  It should 
output "Number of threads = 1, My rank = 0"

Also, can you post the output of ompi_info ?  I think you might still have some 
path mixups.  A successful OpenMPI build with this simple program should just 
work.

If you still have the other OpenMPIs installed from the binaries, you might 
want to try uninstalling all of them and rebooting.  Also if you rebuilt 
OpenMPI and helloworldMPI with VS 2010, make sure that helloworldMPI is 
actually linked to those VS2010 OpenMPI libs by setting the right lib path in 
the Linker options.  Linking to VS2008 libs and trying to run with VS2010

OK, that's what orte_rml_base_select failed means, no TCP connection.
But you should be able to make OpenMPI & mpiexec work without a network
if you're just running in local memory.  There's probably a runtime
parameter to set but I don't know what it is.  Maybe Jeff or Shiqing can
weigh in with what that is.

Hmmm.  Two things.  Can you run helloworldMPI.exe on it's own?  It
should output "Number of threads = 1, My rank = 0"

Also, can you post the output of ompi_info ?  I think you might still
have some path mixups.  A successful OpenMPI build with this simple
program should just work.

If you still have the other OpenMPIs installed from the binaries, you
might want to try uninstalling all of them and rebooting.  Also if you
rebuilt OpenMPI and helloworldMPI with VS 2010, make sure that
helloworldMPI is actually linked to those VS2010 OpenMPI libs by setting
the right lib path in the Linker options.  Linking to VS2008 libs and
trying to run with VS2010 dlls/exes could cause problems too.

Here's a MPI Hello World project based on your code.  It runs fine on my

the Debug directory.

Run it with
