=The TUFLOW Software Suite=
The TUFLOW Software suite has a range of solvers. Each interact differently with your hardware so pairing the correct solver (or the range of solvers you want to run) and hardware is an important consideration. A brief summary of each
* TUFLOW Classic: A single model run can only use the CPU and cannot be run across multiple CPU cores or GPU hardware. In general terms: The maximum model size is dependent on the available CPU RAM and the runtime is driven by the CPU speed, architecture and cache size.
* TUFLOW HPC - Run on CPU Hardware: A single model run uses the CPU and is parallelised to run across multiple cores. In general terms: The maximum model size is dependent on the available CPU RAM and the runtime is driven by the CPU speed, the number of cores available to be run in parallel, architecture and cache size.

=GPU Advice=
TUFLOW HPC on GPU Hardware is typically our fastest solver for 1D/2D pipe and
* TUFLOW HPC supports CUDA enabled NVIDIA GPU cards. For list of supported CUDA enabled graphics cards please visit the <u>[https://developer.nvidia.com/cuda-gpus NVIDIA website]</u>.
* TUFLOW HPC on GPU Hardware can be run in either single or double precision. However, for the vast majority of flood applications single precision is sufficient. We typically run our models on single precision. If you are unsure we recommend running with both the single and double precision solvers and comparing your results.
