Information for Applications' Teams
This webpage provides a basic guidance for the VECMA application developers and/or maintainers.
The VECMA directory
Each resource provides a dedicated directory and disk space for VECMA users. This directory is shared among all VECMA participants.
The locations of VECMA directories on resources
| Resource | Location | MODULEPATH |
|---|---|---|
| Eagle | /home/plgrid-groups/plggvecma/ | /home/plgrid-groups/plggvecma/.qcg-modules |
| SuperMuc NG | ||
| Bull |
The main VECMA module
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 when they run a QCG job (also inside an interactive one), however, in case of regular queuing-system jobs, the $MODULEPATH won't be automatically updated, thus the module won't be visible. Therefore it is advised to add the appropriate command to users' .bashrc. In case of EAGLE cluster the line extending $MODULEPATH should look as follows:
export MODULEPATH=$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 VECMA directory structure
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 |
Module naming conventions
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 |
