FAQ

• Why should I use ARTÌS+GAIA?

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

• Is it Open Source / GPL software?

No! Please carefully read the 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.

• 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.

• 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
