Runtimes for GPU benchmarks
GPU 44-101 times faster than CPU for 2 m grid dependent on number of GPU cards
GPU 18-26 times faster than CPU for 10 m grid dependent on number of GPU cards
Using Multiple GPUs 1.6 to 2.3 times faster than 1 GPU for 2m model

GPU performance increases with increasing model size as does the use of multiple GPUs where initialisation isn’t the major factor in run times.

Introduction
We frequently get asked, "What is the minimum or recommended hardware to use for TUFLOW modelling". This is always a tricky question, as the answer depends on the type and size of the models you are going to be run. For a small model, TUFLOW should run on any modern PC or laptop that is capable of running Windows XP or later. However, for large models there may be requirements for a hefty computer running a 64 bit version of Windows.
The tables below showing computer specifications and model run-time should help you compare systems.
In this page we outline a hardware benchmark model which is available to download from the TUFLOW website the model can be simulated without a TUFLOW dongle (license). This makes it easy to benchmark on a range of computers and the results are complied below.
We have typically found that the CPU speed is the largest influence on TUFLOW runtimes, with the RAM speed also having an influence for large models. In order to quantify this we are compiling the computational times required for a range of different machines.
Benchmark Model
The benchmark model is based on a “challenge” issued prior to the 2012 Flood Managers Association (FMA) Conference in Sacramento, USA. There is more information on the model setup and purpose in the FMA challenge model introduction.
This hardware benchmark is based on the second challenge which involves a coastal river in flood with two ocean outlets. The model has been modified slightly (mainly in terms of the outputs). It is setup to use both the TUFLOW "classic" (CPU) and TUFLOW GPU (graphics card) solvers for a range of cell sizes.
Cell sizes
| Cell Size (m) | Number of cells |
|---|---|
| 30 | 80,887 |
| 15 | 323,536 |
| 10 (GPU only) | 727,865 |
The model runs for three days of simulation time (72 hours). The approximate run time for the 30m model on the CPU is likely to be ~20min and for the 15m version approximately 4 hours. Given the runtime for the CPU model at 10m resolution is likely to be > 12 hours, this is skipped in the benchmark (this can also be run with a licence).
To participate in the benchmark, please follow the steps below:
- Download the model from https://www.tuflow.com/Download/TUFLOW/Benchmark_Models/FMA2_GPU_CPU_Benchmark.zip
- Extract the model on a local drive of the computer you would like to benchmark.
- Navigate to the TUFLOW\runs\ folder and run the "Run_Benchmark.bat" file. This checks if you are running a 32 or 64 bit system and then runs the benchmark. This also generates some output files that contain more information on the processor, memory and GPU that you are using.
- Email the _ TUFLOW Simulations.log, cpu.txt, ram.txt and GPU.txt files to support@tuflow.com and we will includes these in the results tables below.
A nVidia graphics card that is CUDA compatible is required to run the GPU model . For more information on this please see the release notes.
The computer information is determined in the batch file using the wmic and dxdiag commands.
CPU Results
The following table summarises the runtimes for a range of computers. More will be added when additional results are obtained. The table is ordered based on the combined 30m and 15m runtimes, with the fastest computers at the top of the table.

GPU Results
The following table summarises the runtimes for a range of computers. More will be added when additional results are obtained. The table is ordered based on the combined 30m, 15m and 10m runtimes with the fastest computers at the top of the table.
The GPU benchmark only uses a single GPU card. TUFLOW GPU can be run across multiple nVidia GPU devices. However, the benefits of these are typically more noticeable for larger models with more than 1 million cells. A number of additional benmarking tests have been completed on a 2m model and multiple GPU cards.

Discussion
The below preliminary results of the benchmark models have been based on the data submitted so far.
Preliminary CPU Results
The below comparison of the CPU results presents a few interesting points for discussion:
- The runtimes for both models display similar variance as a percentage of the total time across hardware capabilities (36% and 39% relative standard deviation for the 30m and 15m models respectively).
- The runtimes for both the 15m and 30m model show variance largely linked to CPU frequency but not totally. The results are dispersed, perhaps reflecting chip variability, chipset or other systems factors.
- The difference in runtime between the fastest and slowest hardware (~440-500%) is much less than the difference in average runtime for the 30m and 15m models (1,110%). Thus, nothing can improve your model runtime like efficient model design!
Preliminary GPU Results
- Similar to the CPU results, decreasing the model cell size increases the variability in what runtime you'll get per CUDA cores
- Unlike the CPU results, the variability in runtimes to cards is greater than the change in model cell size. Thus, it could be argued that the runtime of your GPU model is more dependent on the type of card you have than the runtime of your CPU model is on the processor frequency.
- From the results received so far, the NVIDIA GTX 980 seems a crowd favorite and performs well. It is likely that as model size increases that the Titan Black and K6000 with 2880 cores will result in faster runtimes. The NVIDIA GeForce GTX 1080 is topping the table.
Average reduction in Runtime from CPU to GPU
When comparing the CPU and GPU runtimes for the 15 and 30 m models on average the following runtime improvments are achieved:
- 11.0x reduction in runtime for the 30m model (80,000 cells)
- 20.4x reduction in runtime for the 15m model (325,000 cells)
These results highlight the relationship between GPU/CPU runtime reduction relative the number of the cells in a model. The reduction ratio increases with the size of the model (number of cells). Up to a 100x reduction in runtime have been recorded using a 18,000,000 cell GPU model refer Large Model GPU Benchmarking.
Large Model GPU Benchmarking
In addition to the benchmarking completed on the 10m, 15m and 30m models, a number of tests were completed by running the FMA Demo Model 2 at a 2m resolution on up to four GPU cards.The 2m model has approximately 18.2 M cells and was simulated for the following test cases:
The five runs detailed above were also re-run on the 10m grid.
Explanation of Tabulated Results
The large model benchmarking results are summarised in the below table. The contents of each column is detailed as follows:

The results of the large model GPU testing indicate:
If you have done any testing on much larger models, then we would love to hear how you have gone!!! Please send in details to support@tuflow.com.
General Comments on GPU Model Memory Requirements
Without infiltration, you can model about 15 million cells per GB of GPU RAM, with infiltration it is about 12 million cells per GB. A card with 6 GB of RAM allows about 75 million cells. However, as the pre and post processing is handled by the TUFLOW engine, such a model would also require significant amounts of motherboard RAM as well. You can also run models across multiple GPU cards allowing for even larger models to be simulated. For example it is possible to run 180 million cells with infiltration losses over four GTX680 cards (4 GB each).
