JSC Test

Free allowance: Test projects grant a computing-time budget on JURECA, the JUWELS cluster or the JUPITER Booster for up to four months, optionally with about two person-weeks of expert support from a JSC Simulation and Data Lab, with applications accepted throughout the year.

Composes with	The two person-weeks of SDL porting support is worth more than the node hours for a solo applicant, and it is the one JSC tier that would help a code become competitive, but it is behind German employment.
Reliability	no reliability event recorded
Notes	JSC publishes no core-hour figure for test projects: the page says 'a certain number of core-hours' and never quantifies it, so the field is null rather than guessed. The extended-support variant is the unusual offer, because a Simulation and Data Lab contributes staff time, which is the scarce input for a solo researcher. The explicit sentence that nationality is irrelevant while German employment is required is the cleanest statement of the binding constraint found in the German stack.
