Greg,

Thanks for your help.

First, I should say I am new to OpenMPI. We are set up for MPICH2. I am an experienced Eclipse user, however, and would like to try Eclipse, including installing Tau. This is the reason for using OpenMPI.

I modified openmpi-default-hostfile, as you suggested, and I can now run on the command line with:

mpiexec --prefix /clhome/EVANS/openmpi -n 5 helloWorld

(Note: No machine file.) My .login sets MPICH2 paths. I can reset the paths on the machine on which I am running, but I need the –prefix for the nodes to work. The paths are set for OpenMPI in a script that I use to start Eclipse, but I would guess there is still the problem with the nodes that –prefix fixes. Can this be handled in PTP?

It still doesn’t work in Eclipse. I get the same exception. There is only one machine (Machinemachine0, no typo) in the drop-down menu in the launch configuration. Just what is this machine anyway and where is it set? I would expect a list of nodes like in the openmpi-default-hostfile. The launcher seems like the place to put this information. It also seems like there should be a place for arguments to mpiexec in addition to those for the program. Perhaps I have missed something.

I tried restarting Eclipse with –clean. It didn’t help.

The file ptp_orte_proxy exists and looks OK. I did not get errors during sh BUILD. I added the following lines to BUILD, first:

--------------------------------------------------------------------------------

# Added manually to the original since installation is non-standard

export CFLAGS=-I/clhome/EVANS/openmpi/include

export LDFLAGS="-L/clhome/EVANS/openmpi/lib -Wl,-rpath,/clhome/EVANS/openmpi/lib"

--------------------------------------------------------------------------------

(BTW the directions on the help page need some line breaks, and this isn’t exactly what I took them to say, but it seems like it should do what I think they indicate is needed.)

My current Eclipse output is:

Looking to the future: I use MPE. Is there an easy way to point OpenMPI to the version that is already installed? There is a paragraph about the advantages of using the mpicc wrapper somewhere I looked. Can the OpenMPI mpicc be fixed to specify MPE with options like “-mpe=log” as in MPICH2 or do I need to use –L and –l?

Thanks again,

-Ken

Hi Ken,

PTP 1.1 relies on OpenMPI for information on the nodes in the cluster. This version doesn't have any support for machine files. If you edit /clhome/EVANS/openmpi/etc/openmpi-default-hostfile and add the hostnames of the other machines in the cluster then you should see them. You will also be able to use 'mpirun -np 25 helloWorld' to run your application.

Also, it doesn't look like PTP built correctly. Please check in /clhome/EVANS/eclipsePlugins/eclipse/plugins/org.eclipse.ptp.linux.x86_64_1.1.0/bin for an executable called ptp_orte_proxy. Were there any errors when you run the BUILD script?

Regards,

Greg

Hi,

I have set up Eclipse, PTP, and OpenMPI according to the directions. I can’t run anything using PTP, though. In addition, it says there is only one machine, Machinemachine0, in the launcher. This is on a 64-bit Linux cluster.

I _can_ run MPI programs using OpenMPI. However, in order to use other nodes than the head node, I need to use:

mpiexec --prefix /clhome/EVANS/openmpi --machinefile machines -n 25 helloWorld

I see no place in Eclipse | Preferences to set the machine nodes.

I can also run an OpenMPI parallel program using the External Tools launcher.

I have set up a launch configuration as described in Help. When I run it, I get:

--------------------------------------------------------------------------------

Exception occurred during launch

Reason: Error within Debug UI:

Details: Java.lang.reflect.InvocationTargetException

--------------------------------------------------------------------------------

(BTW I am using Run, not Debug, to launch.)

My environment is set up in .login to point to an MPICH2 installation. I reset PATH and LD_LIBRARY_PATH in the script that launches Eclipse. BTW this was done in the shell in which I ran “sh BUILD”. Thus there _could_ be a conflict, but it doesn’t look like there should be.

I can _build_ MPICH2 applications in an MPICH2 project by setting the PATH and LD_LIBRARY_PATH in the environment for the make Project. (I am using Standard, not Managed C / C++ builds). And I can _build_ OpenMPI applications in an OpenMPI project without setting PATH and LD_LIBRARY_PATH. Thus, it seems I have the paths set up OK.

I get these messages, which I don’t understand, when starting Eclipse.
