Description

Logging reveals that there is a lot of simulations every week where NUM_CPU is set to 1 but Eclipse still runs in parallel.

These users get a warning post-simulation, but this turns out not to be sufficient.

One should explore possibilities for blocking this, as this anti-pattern steals CPU-resources from other users, and gives users a much lower pending time that what is correct.

Research direction

No files or tests are named. Start by locating the code that handles NUM_CPU and Eclipse parallel execution, then inspect the existing post-simulation warning. Done means simulations with NUM_CPU set to 1 cannot run Eclipse in parallel, with the behavior covered by appropriate tests.
