Re: [epp-dev] MPI debugging using PTP

["Dr. Yehuda Singer" <yehuda.singer@xxxxxxxxx>]

Dear Jonah

Thanks for your response.

 

I develop automatic parallelization. One mode is that we use multiple processors connected in a network. We want that all the cores of each processors will work efficiently on

The application.

The first stage is to take a 40 cores machine and run the application in groups of 8 cores using MPI.

 

The only way to do it is using the PTP.

In any case the Eclipses scientific activates the PTP.

 

I hope that we can make the project alive.

 

Best regards,

Yehuda

There is nowhere to send it to. The PTP project (https://projects.eclipse.org/projects/tools.ptp) has been archived due to a lack of community investment. If you are interested in restarting the project you can start that process - quoted here for your convenience:

 

If there is sufficient community interest in reactivating an archived Project, the Project can start again with a Creation Review. As there must be good reasons to have terminated a Project, the Creation Review provides a sufficiently high bar to prove that those reasons are no longer valid.

Dear Jonah

Thanks for your Email.  The PTP is integrated in the Eclipse for scientific which include C/C++ and Fortran. You are right that the PTP has not been used for the following reasons:

1. The script for MPICH2 to start debugging was full with logical errors. I revised it and now it works. I can send it to you.
2. The SDM package which is written in Chas not been maintained.  I organized it as an Eclipse C/C++ project and changed definitions which do not follow the C standard. C98

Let these bad coding to be compiled. Now it is compiled and work. I can send you the SDM as an Eclipse project as well.

 

If you give me the source of the mpiexec and some documentation, I will do the same: repair and send it back to you.

Hi,

 

The PTP project (https://projects.eclipse.org/projects/tools.ptp) has been archived due to a lack of community investment. 

 

Your email seems to be the same or continuation of https://github.com/eclipse-packaging/packages/issues/115#event-12339274344

Dear All,

 

 

We want to debug MPI programs using the cores on a 16 core machine running Linux.

We have installed the SDM package.

 

We activate the SDM package as a process: /usr/local/bin/sdm/SDM –debug=gdb – debugger_path=/usr/bin –port = 4118 –host=yehuda-linux2  --routing_dile=routes/Routing_file_info.part

 

We do: mpiexec – n 6 –host=yehuda-linux2  -envMPIEXEC_PORT_RANGE=4118:10000  Exe_mpi_debug.out

 

The executable file runs and give results for RANK 0.

No breakpoint is activated even we set the command to break in the entry of the main.

 

 

Best regards,

Yehuda
