Supercomputer

The COMPSs Framework can be installed in any Supercomputer by installing its packages as in a normal distribution. The packages are ready to be reallocated so the administrators can choose the right location for the COMPSs installation.

However, if the administrators are not willing to install COMPSs through the packaging system, we also provide a COMPSs zipped file containing a pre-build script to easily install COMPSs. Next subsections provide further information about this process.

Installation

To perform the COMPSs Framework installation please execute the following commands:

$ # Check out the last COMPSs release
$ wget http://compss.bsc.es/repo/sc/stable/COMPSs_<version>.tar.gz

$ # Unpackage COMPSs
$ tar -xvzf COMPSs_<version>.tar.gz

$ # Install COMPSs at your preferred target location
$ cd COMPSs
$ ./install [options] <targetDir> [<supercomputer.cfg>]

$ # Clean downloaded files
$ rm -r COMPSs
$ rm COMPSs_<version>.tar.gz

The installation script will install COMPSs inside the given <targetDir> folder and it will copy the <supercomputer.cfg> as default configuration. It also provides some options to skip the installation of optional features or bound the installation to an specific python version. You can see the available options with the following command.

$ ./install --help

Attention

If the <targetDir> folder already exists it will be automatically erased.

After completing the previous steps, administrators must ensure that the nodes have passwordless ssh access. If it is not the case, please contact the COMPSs team at support-compss@bsc.es.

The COMPSs package also provides a compssenv file that loads the required environment to allow users work more easily with COMPSs. Thus, after the installation process we recommend to source the <targetDir>/compssenv into the users .bashrc.

Once done, remember to log out and back in again to end the installation process.

Attention

After the installation, it is MANDATORY to configure the installation with the supercomputer characteristics (e.g. queuing system, hardware, etc.).

The configuration is thoroughly described in Section Supercomputer configuration
