RedScarf Reference Dataset

This dataset comprises the results of an extensive set of simulation-based experiments that compare the performance of on-chip communication architectures. These experiments were performed using the RedScarf simulation environment, and the dataset includes raw data (simulation logs) and analyzed data (latency, jitter, and throughput) collected from the simulation of several communication architectures working under different traffic patterns. The dataset also includes the configuration files used to configure each experiment. The design space explored in these experiments includes:

Traffic Scenarios used:
• Uniform;
• Matrix transpose;
• Complement;
• Butterfly;
• Perfect Shuffle; and
• Bit-reversal.

Topologies evaluated:
• 2D Mesh;
• 3D Mesh;
• 2D Torus;
• Full Crossbar;
• Bus emulated by an exclusive N-1-N (with only one exclusive channel) switched router; and
• Chordal ring.

Routing algorithms evaluated on a 2D Mesh:
• XY;
• Negative First;
• North Last;
• West First; and
• Odd-even.

Arbiter policies evaluated on a 2D Torus:
• Static;
• Rotative;
• Random; and
• Round-robin.

Buffering dimensioning schemes evaluated on a 3D Mesh:
• 4-flit input buffer;
• 8-flit input buffer;
• 16-flit input buffer;
• 32-flit input buffer;
• 4-flit input and 4-flit output buffers;
• 8-flit input and 8-flit output buffers; and
• 16-flit input and 16-flit output buffers.

Metrics evaluated:
• Latency (average, min, and max);
• Accepted Traffic (throughput); and
• Jitter (latency distribution).
