AquinTutor · HPC Lab

HPC job simulator.

Configure a cluster (nodes × cores × interconnect latency). Pick a workload (matrix multiply / Monte Carlo / N-body / image filter). Watch the real Gantt chart, Amdahl's-law speedup curve, and per-core utilisation heatmap unfold in real time. Pure browser-side math.
