Casting simulation, at GPU speed
- 451×
Against one CPU core
1851 MLUPS on a single Tesla V100 against 4.1 MLUPS on one core of the same machine.
- 55×
Against the whole CPU node
The same GPU run against all 18 cores of that machine under MPI, at 33.9 MLUPS. This is the figure we quote.
- 40.5×
On the heat conduction kernel
5422 MLUPS against 134 MLUPS on 36 CPU threads, both sides running the same arithmetic.
One machine, one Tesla V100, same kernel on both sides — nothing scaled or extrapolated. The node figure is far below the single-core ratio because the CPU itself only gains 8.3× across its 18 cores: lattice Boltzmann is bound by memory bandwidth, not clock speed.
Compute Faster
GPU-Native Architecture
TesboFlow runs the entire CFD pipeline on GPU — mesh, solver, linear algebra, post-processing. No CPU bottleneck. No data transfer overhead. Pure parallel computation.
- No CPU bottleneck
- Massive parallelism
- High memory bandwidth
The same GPU-native approach carries TesboLBM: mould filling and solidification also run start to finish on the GPU.

Test fluid mechanics in real time directly in your browser. Choose a preset airfoil, a cylindrical vortex-shedding obstacle, or draw custom solid boundaries with your finger to watch vorticity and pressure waves evolve.
TesboAI · AI + CFD research
Intelligence, native to the solver.
Because the engine is GPU-native, models train on its data and run in its memory. Here's a result, not a promise.

A session replayed — asking, changing conditions, comparing runs; every figure computed by the GPU solver.
Research prototype, in development. A short replay of one real session — the full session is on the TesboAI page.
The GPU era of simulation
Built for speed. Powered by GPU.
Speed isn't a feature — it's what makes simulation usable. When an answer takes minutes instead of days, engineers stop waiting and start exploring. We build for the GPU from the ground up to make that the default.
This will change the world.
