TUFLOW Message
WARNING 2803 - When running Quadtree solver on GPU, only a single GPU can be used. Reduced from: X

Alternate Message
WARNING 2803 - When running Quadtree solver on CPU, only a single CPU thread can be used. Reduced from: X

Message Type
WARNING

Description
For TUFLOW Releases 2020-10 and earlier, the quadtree solver can run on a single GPU or single CPU thread only.

Suggestions
If using GPU, remove the request to use multiple GPUs either from batch file or .tcf file to omit this warning.
If CPU is used for HPC, 4 threads are used as default from the 2020-10 releases. If CPU is used for Quadtree, the number of threads is reduced to one for releases prior to 2023. Multiple GPU and CPU threads are supported for Quadtree from the 2023 release.
