Starting with version 6.3 of ARTEMiS, the SSN solver is capable of being executed on multiple processors, without any delays. In most cases, this improves the performance of the solver.

Note: This mode requires RT-LAB 10.3 or later.

The parallel mode is activated only if multiple cores are allocated for a specific subsystem. To allocate additional cores, use the advanced view of the assignation page:

Select ... in the Cores column to activate the core selection dialog. Select the number of cores and optionally, select specific cores. Unspecified cores are allocated automatically by the system using the assignation rules described in the RT-Lab User Guide.

When multiple cores are allocated for a given subsystem, SSN groups are automatically divided among available cores so that the total computation time is minimized.

Thus, the number of groups and their relative size will have a direct impact on the possible performance improvements for the parallel mode. In rare cases, the situation could be without significant gains. Experimentation is often needed to find the optimal configuration. Experience shows that parallelism gains in SSN tend to saturate with more than 5 or 6 cores.
