.. image:: _static/DIRAC-logo.png :width: 300pt :target: http://diracgrid.org The DIRAC interware is a complete Grid solution for one, or more than one community of users that need to exploit distributed heterogeneous resources. DIRAC forms a layer between a community and various compute resources to allow optimized, transparent and reliable usage. The types of resources that DIRAC can handle include: * *Computing* Resources, including Grids, Clouds, HPCs and Batch systems * *Storage* Resources * *Catalog* Resources Many communities use DIRAC, the oldest and most experienced being the `LHCb `_ collaboration. Other communities include, but are not limited to, `Belle2 `_, `ILC `_, and `CTA `_ DIRAC source code is open source (GPLv3), written in `python `_, and hosted on `github `_.
