Each resource provides a dedicated environment for VECMA application teams and end-users. This webpage provides information how to use this environment.
Each resource provides a dedicated directory and disk space for VECMA. This directory is shared among all VECMA participants.
| Resource | Location | MODULEPATH |
|---|---|---|
| Eagle | /home/plgrid-groups/plggvecma/ | /home/plgrid-groups/plggvecma/.qcg-modules |
| SuperMuc NG | ||
| Bull |
In order to simplify usage of VECMA environment, the resources have set up the top-level module for VECMA. This module will configure the common settings for all VECMA participants. The vecma module should be available for users out-of-the-box when they run a QCG job (also interactive one), however, in case of regular jobs, started without QCG, the $MODULEPATH won't be automatically updated and the module won't be visible. Thus it is advised for users to add the command extending $MODULEPATH to their .bashrc files. In case of EAGLE cluster it will look as follows:
export MODULEPATH=$MODULEPATH:/home/plgrid-groups/plggvecma/.qcg-modules
The vecma module could be loaded with the following command:
module load vecma
When loaded, the module set up the $VECMA_DIR environment variable that points to the shared directory.
The shared directory $VECMA_DIR has the following structure:
| Path | Description |
|---|---|
$VECMA_DIR/Apps | The directory for use by application providers |
$VECMA_DIR/Apps/App1 | The directory for application App1 |
$VECMA_DIR/Apps/AppN | The directory for application AppN … |
$VECMA_DIR/Common | Common stuff, possibly useful for more than one team |
$VECMA_DIR/.qcg-modules | The directory for VECMA Environment Modules |
The modules created for the VECMA project follow the following scheme:
| Module | Description |
|---|---|
vecma | The main module for the VECMA project. Will load basic settings |
vecma/apps/App1 | The module for a single application (e.g. App1) |
vecma/common/Item1 | The module for a common software item (e.g. Item1), possibly useful for many teams |
