TUFLOW Message
ERROR 2420 - It is recommended to run TUFLOW HPC or GPU Solver using single precision (SP) builds. To run TUFLOW HPC or GPU Solver using a double precision (DP) build specify "HPC DP Check == OFF".

Alternate Message
NA

Message Type
ERROR

Description
A model simulation using the TUFLOW HPC/GPU Solver, has been started using the double precision version.

Suggestions
The HPC/GPU solver due its explicit formulation and being depth based does not usually require to be run in double precision mode. There can be substantial speed gains using single precision on some GPU cards, and there is a significantly less memory footprint. If double precision is desired or required for the HPC/GPU Module specify “HPC DP Check == OFF”/“GPU DP Check == OFF” in the .tcf file, and run using a double precision TUFLOW.exe.
