A100 CUDA run
GridSim - 2026-07-02 14:55:10 UTC
code: git 8ec809d2-dirty | GridSim.Core v0.1.0.0 | build Release
runtime: .NET 10.0.9 X64 GC=Server
machine: keen-darwin Ubuntu 24.04.3 LTS
cpu: AMD EPYC 9554 64-Core Processor - 28 logical cores - 118 GB RAM
backend: gpu/cuda (NVIDIA A100 80GB PCIe [CUDA] - FP64 is fast (data-centre GPU) (driver probe: cuInit=0 driverVer=12080 cuDeviceGetCount rc=0 count=1))
run: bench-matrix cases=25 engines=5 runs=5 parallel=1 note="A100 80GB PCIe R570 + EPYC 28c: parallel=1 (uncontended per-case latency)"
Run note: A100 80GB PCIe R570 + EPYC 28c: parallel=1 (uncontended per-case latency)
Full solver x backend matrix over the whole archive. Every engine below is swept across
every case (Q-limits off, tol 1e-8, max 100 iters). Cells: conv / iters / mismatch / mean ms.
BFS is radial-only (meshed cases show n/a). Dense solves are memory-gated (few concurrent)
and ordered small->large; GPU engines run one case at a time and skip cases >3000 buses
(consumer-GPU FP64 is slow). Absent accelerators are simply not listed as engines.
Engines this run: cpu-dense - Dense Newton-Raphson, CPU LU; cpu-sparse - Sparse Newton-Raphson, CPU (direct LU / ILU0-BiCGSTAB); bfs - Backward-forward sweep (radial feeders only); cuda-dense - Dense NR, CUDA (gpu/cuda (NVIDIA A100 80GB PCIe [CUDA] - FP64 is fast (data-centre GPU) (driver probe: cuInit=0 driverVer=12080 cuDeviceGetCount rc=0 count=1))); cuda-sparse - Sparse NR, CUDA (gpu/cuda (NVIDIA A100 80GB PCIe [CUDA] - FP64 is fast (data-centre GPU) (driver probe: cuInit=0 driverVer=12080 cuDeviceGetCount rc=0 count=1)))
ROCm/AMD: --gpu requested but no device answered.
