# SYNTHETIC EXAMPLE OF THE `ib_write_bw` OUTPUT FORMAT. # Hand-written to exercise tools/parse_ib_bw.py. NOT captured from any fabric, and not a # specification for any adapter. Every bandwidth figure below is a ROUND INVENTED number # chosen to make the shape of a sweep visible -- a per-message floor at the small end, a # flat ceiling at the large end, and a knee between them. Do not quote any of it. # The peak and average columns are equal here because the gap between them is a property # of a real run, and inventing one would be inventing a measurement. # See samples/README.md. --------------------------------------------------------------------------------------- RDMA_Write BW Test Dual-port : OFF Device : mlx5_0 Number of qps : 1 Transport type : IB Connection type : RC Using SRQ : OFF TX depth : 128 CQ Moderation : 1 Mtu : 4096[B] Link type : IB Max inline data : 0[B] rdma_cm QPs : OFF Data ex. method : Ethernet --------------------------------------------------------------------------------------- #bytes #iterations BW peak[Gb/sec] BW average[Gb/sec] MsgRate[Mpps] 2 1000 0.20 0.20 12.500000 8 1000 0.80 0.80 12.500000 64 1000 6.40 6.40 12.500000 512 1000 51.20 51.20 12.500000 4096 1000 100.00 100.00 3.051758 32768 1000 180.00 180.00 0.686646 262144 1000 200.00 200.00 0.095367 2097152 1000 200.00 200.00 0.011921 8388608 1000 200.00 200.00 0.002980 ---------------------------------------------------------------------------------------
