Re: [ptp-user] problems with resource manager
Greg,

It worked ! Thanks ! Solves this problem, but yes, "it shouldn't be necessary".

Best,

Frederico.

Fredrico,

Try adding executing the command "export PATH=$PATH:/opt/openMPI_GF/bin" then re-launch eclipse. This sounds like there is definitely a path problem, though I'm not sure why adding it to the install location option doesn't work.

Regards,
Greg

Beth,

I don´t see why it seems to you that I have tried to set up the resource manager to a remote host .... but I'm quite a newbie with these tools, so ....

Also what confuses me is that "the same setting" (meaning the equivalent options with the corresponding different paths for example) worked in my Mac, and when I tried in the machine running linux (Ubuntu 11.04 64 bits) it didn´t.

Here´s in detail what I have:

1) I have compiled openMPI v1.4.3 with no special options, just specifying the gcc/gfortran compilers and the installation directory --prefix=/opt/openMPI_GF

On a shell I can execute /opt/openMPI_GF/bin/ompi_info and it prints the related information.

2) I have downloaded and installed Eclipse 3.7.0 64 bits (the 32 bits version crashes ... but let's stay focused) and also PTP version 5.0.0.201105041745

3) Now, I go to the Parallel Runtime perspective and at the Resources Managers panel, I click on "Add resource manager", chose OpenMPI type, Remote service provider: Local ; Connection name: Local; Tunneling Options: None ; Local address: localhost.

Select the openMPI version: openMPI 1.4; leave Use default commands; install location: /opt/openMPI_GF/bin

Change the name to: OpenMPI_GF@Local and click on Finish.

4) When I ask to start the resource, and I get the error that I mentioned before:

"Failed to start resource manager

Reason: Failed to create remote process for OpenMPI discover command.

Details: Cannot run program "ompi_info": Unknown reason"

My goal: Run locally a Fortran code that uses MPI to run in parallel, and to compile and test it, use openMPI. What am I doing wrong ?

Thanks for the help.

Frederico.

Federico,
It sounds like you tried to set up the resource manager to a remote host but you really needed it to be to your local machine?

    It sounds like your path is not getting set correctly. Try the command "ssh <your_host> ompi_info" to see if the path is set correctly for remote commands.

I am running on my local machine. On another machine that I use (also to run locally), I did not have to worry about remote commands and it worked properly.

    You can also set the path manually by editing the resource manager configuration, unchecking "Use default location", and entering the location of the Open MPI commands (normally the installation bin directory)

I think I have this part correctly set, I did uncheck the use of the default location and set it to the location of the bin directory.

Bes,

Frederico.

      Hi,

      I am having trouble to start a resource manager. This is the error message I get:

      Failed to create remote process for Open MPI discover command.
      Cannot run program "ompi_info": Unknown reason


      on a shell I can execute ompi_info.

      I have compiled openMPI with different compilers (like gcc/gfortran, or intel compilers), but I always get the same error.

      I am using eclipse indigo, running on a ubuntu 11.04 x84_64.

      I had no trouble to setup (and run) parallel local jobs, also using eclipse indigo, on a Mac. The "only" difference between the two is that on the Mac I am running a 32 bits eclipse, and under the Ubuntu it is the 64 bits version, since the 32 bits crashes.

      Any help ?

      Thanks.
