| Mike,
I'd lay money on this being a path problem and somehow the 1.2 version is being picked up instead of 1.3. If I run this command from the command line under 1.2, I get the following:
$ mpirun -xml -display-map -np 4 -bynode test_prog [Jarrah:52532] Warning: could not find environment variable "-display-map" -------------------------------------------------------------------------- Failed to find the following executable:
Host: Jarrah Executable: -m
Cannot continue. --------------------------------------------------------------------------
Does linux come with Open MPI pre-installed these days? I think we changed Remote Tools so that it does not pass the local environment to the remote machine because it seemed like this is probably not what you want. If you've installed Open MPI in a non-standard place, you should be able to specify the path in the resource manager configuration to overcome this.

The command ptp is trying to run is:

On stderr I get:

On stdio (this is what the XML parser is failing on):
1 additional process aborted (not shown)
1 additional process aborted (not shown)
This is completely different output then when I run the same command in an SSH terminal, in which case it works.
I'm using OpenMPI 1.3 on linux and the resource manager is set up with remote tools.
Could this be a problem with the SSH connection established by remotetools, maybe the command is running in a different environment somehow?

Re: [ptp-dev] can't launch executable |
Hi Mike,
Because of the "Content is not allowed in prolog." message, I suppose the the Open MPI plugin is not able to understand the output written by mpirun. It does not seem to be a valid XML expected according to the -xml -display-map flags. Could you send my this output? Does mpirun print some warning or error message before of the XML?

I'm pretty sure that I had the resource manager set to the right version of OpenMPI.
I think its interesting how I get different results depending on if remotetools or RSE is used for the connection.
Otherwise I guess I just have to keep running PTP in the debugger and hopefully get somewhere.

Re: [ptp-dev] can't launch executable |
Mike,
I'm pretty sure the "-display-map is not an executable" problem is because the resource manager version is set to 1.3, but you're using Open MPI 1.2. Try changing this in the resource manager configuration wizard (double click on a stopped resource manager).
Hopefully Daniel can shed some light on the problem with the 1.3 version.
Regards,
Greg

I have a simple "Hello World" remote project,. To keep things simple I built the executable manually on the server using the mpicc command.
I have installed OpenMPI 1.3 on our linux server. I created an OpenMPI resource manager using a remote tools connection. Whenever I try to do a launch I get the following error:
Failed after executing command to launch parallel application.
Failed to parse output of Open MPI command. Check output for errors.
Content is not allowed in prolog.
This is an XML parser error when parsing the output of the command. I enabled tracing by setting all the fields in DebugUtil to true. The command that its trying to execute seems to be correct:
mpirun -xml -display-map -np 4 -bynode /home/mkucera/projects/openmpi_test/src/a.out
If I copy the command into a ssh window it runs the program just fine. But when PTP tries to run the command it never works.
I've tried a bunch of different things to get this to work. I tried installing OpenMPI version 1.2 but still got similar problems. In this case the error says that '-display-map' is not an executable. Again the command itself looks fine but when PTP executes the command it doesn't work.
I tried to use RSE for the rm connection with OpenMPI 1.2 and this time it was actually able to run the command. However the debugger would not run. I kept getting errors about broken pipes.
What am I doing wrong? Any help would be greatly appreciated.

<graycol.gif>Greg Watson ---11/04/2008 12:00:38 PM---We are very pleased to announce the 2.1 release of PTP. This release
We are very pleased to announce the 2.1 release of PTP. This release
includes a wide variety of improvements to the core platform, as well
as adding two significant new areas of functionality. The first of
these is the Remote Development Tools (RDT) which enables C and C++
projects to be located on a remote machine, yet still be accessible
from within the Eclipse environment. The second is the contribution of
the Cell B.E. IDE which enables PTP to be used for the development of
applications for the Cell Broadband Engine. We hope that you find the
improvements to PTP beneficial to the development of your parallel
applications.
The 2.1 release is available for download from http://eclipse.org/ptp/downloads.php
Detailed release notes are available from http://wiki.eclipse.org/PTP/release_notes/2.1
Thanks for the hard work from everyone who contributed to making this
release a success!
Greg
