====== FAQ ======



===== General =====

   * **Why should I use ARTÌS+GAIA?**

> Mainly because it is really fast and provides support for migration-enabled parallel and distributed simulations.

===== License =====

   * **Is it Open Source / GPL software?**

> No! Please carefully read the [[PADS:download]] __before__ downloading it. We aim to open source the ARTÌS+GAIA middleware in future, but we are now unable to provide a detailed roadmap.

   * **Can I include the ARTÌS+GAIA middleware along with my application?**

> No! It is NOT allowed by the license agreement. Your application/model can be based on ARTÌS+GAIA but the middleware packages has to be separately downloaded by the official website.


===== Versions =====

   * **What about the XYZ architecture?**

> We are currently __unable__ to provide the ARTÌS+GAIA binaries for a wide set of architectures. Due to the available resources the ia32 is the only supported architecture.

===== Technical details =====

   * **What is the amount of shared memory available in a Linux machine?**
> /proc/sys/kernel/shmmax provides the maximum size of shared memory segment (bytes).
> This value can be changed but this operation requires the root privileges.
> In example: //echo "67108864" > /proc/sys/kernel/shmmax//
> Increases the shared memory up to 64 MB.

   * **Is it possible to force the middleware to use the TCP protocol also for the local communications?**
> Yes, see the option //TCP_FORCE// in the configuration file //sima.ini//
