Q: How do I download PTP?
PTP is typically installed via the Eclipse Installation Manager (Help > Install new software...). See the PTP download page; check regularly there for new releases, too. The current released version of PTP is 4.0.x.
See the PTP 4.0 release notes for instructions on how to install PTP.
Q: What version of Eclipse and CDT do I need?
PTP 4.0 is designed to work with Eclipse 3.6.x and CDT 7.0.x.
PTP 3.0 is designed to work with Eclipse 3.5.x and CDT 6.0.2.
Q: What version of MPI do I need to run PTP?
PTP supports the following MPI runtimes:
- Open MPI 1.2.x, 1.3.x, or 1.4.x
- MPICH2 1.0.6p1
- IBM's Parallel Environment (PE)
The most recent OpenMPI (1.4.x) is recommended for PTP 4.0.x, although it may work with older releases.
For the Parallel Language Development Tools only, there should be no difference between the different versions of MPI, such as OpenMPI and LamMPI. You just need to configure your project to be built using mpicc rather than gcc (for MPI releases that require that; most do), and to specify the include path to the MPI header files. This should be described in the PLDT help.
Q: What platforms and runtimes are supported by PTP now?
The current release of PTP runs on Linux, MacOS X, and Windows. PTP only supports target systems running Linux, MacOS X, and some kinds of Unix (e.g. AIX).
The Parallel Language Development Tools will run anywhere Eclipse 3.6 and CDT 7.0 will run. It simply requires any version of MPI (specifically, its header files) to aid in the search for MPI artifacts. And an OpenMP header file, if OpenMP analysis is needed.
The Remote Development Tools can be used on Linux, MacOS X, and Windows.
Q: How do I install Open MPI?
You may already have it installed. Try running the following command and check the output:
ompi_info
If this doesn't work, download the latest version from the Open MPI site.
Unpack the distribution and run the commands (note that you may have to add extra options to configure to suit your local site - see the Open MPI help documentation for more information):
./configure --prefix=/path/to/your/ompi/install make make install
At this point it's a good idea to run a small mpi program to test you have installed Open MPI correctly.
mpicc -o testMPI testMPI.c mpirun -np 2 testMPI
Q: How do I build PTP myself?
See the PTP Environment Setup instructions
Q: How do I ask questions about PTP?
Subscribe to the PTP Mailing lists, especially ptp-user, and ask questions there. This is an excellent place to ask new-user questions. The ptp-user list is watched by most of our PTP developers as well as many users, and you can share in their experience. See http://www.eclipse.org/ptp/mailing_lists.php
Q: How do find out more about PTP?
- Read the PTP Help documentation from the PTP Website or download it and read the help within your PTP installation.
- Download slides from previous PTP tutorials
- Ask questions on the mailing lists: See http://www.eclipse.org/ptp/mailing_lists.php
Q: What's the most recent version of PTP?
The current released version is 4.0.x.
See the announcements on http://eclipse.org/ptp which should indicate the latest release number. As of May 2011 this is 4.0.7.
The most accurate latest release number is whatever is found on the update site at http://download.eclipse.org/tools/ptp/updates/helios.
Q: How do I install the most recent released version of PTP?
There are two update sites:
- The Helios update site http://download.eclipse.org/releases/helios contains all the Eclipse projects (as of February 2011 it contains PTP 4.0.6)
- The PTP-specific update site http://download.eclipse.org/tools/ptp/updates/helios may have a more recent release (as of May 2011 it does: 4.0.7)
- Update Sites
- The Helios update site (http://download.eclipse.org/releases/helios) contains the last release of PTP that was built into the Eclipse general update site. Eclipse Helios updates are released only in September and February. This update site (a.k.a. software repository) is enabled by default when you install Eclipse Helios (a.k.a. 3.6). Now (after Feb. 2011) it contains SR2, Eclipse 3.6.2.
- Help > Install New Software.... and install PTP from there
- Help > Check for Updates will find the updates for all your installed features that are found there.
- PTP maintains its own PTP-specific update site with the most recent release of PTP. Bug fix releases can be more frequent than Helios'.
You must enable the PTP-specific update site before the updates will be found.- Enable the PTP-specific update site
- Help > Install new software...
- Click Available Software Sites link
- Enable/check the PTP site:
- Choose OK and then Cancel to return to the Eclipse workbench, and ...
- Now do the update
- Select Help > Check for updates
- Follow prompts like a normal installation
- Select Help > Check for updates
- Enable the PTP-specific update site
Q: I want to live a bit on the bleeding edge. How do I install a more recent PTP build, e.g. to get a bug fix ?
Go to the PTP builds page and find the page for your release (e.g. if you have 4.0.x, find the page with the largest value of x) and download the archive file (ptp-master-xxx) then use that in the Help > Install New Software... dialog.
