TUFLOW Message
ERROR 3017: Required memory exceeds available GPU memory.

Alternate Message
None

Message Type
ERROR

Description
There is insufficient available GPU memory across the specified GPU devices to run the simulation.

Suggestions
If trying to run the HPC Solver in double precision, memory requirements may be significantly reduced by changing to single precision.

Consider if your model configuration can be refined to reduce memory requirements. The key factors that influence memory allocation are:

  • The size of the redundant area around the perimeter of the model;
  • The number of 2D cells, hence the domain extent and the cell size; and
  • The model features utilised.

If additional GPU devices are available, consider running the simulation across extra GPU devices.
