Warnings (Grid Overlay)

When a Grid Overlay performs a calculation, one or more warnings may be displayed regarding the state or completion of the calculation. The warnings listed here are applicable for all Grid Overlay calculations.

Generic Warnings

The following warnings can occur for any Grid Overlay calculation.

Calculation was cancelled

The calculation did not run to completion, because it was cancelled by the user. Depending on the calculation being performed, partial results may be available.

Calc too long forced timeout

The calculation exceeded the allowed calculation time. During business hours (9-17, GMT+1, during weekdays), there is a maximum calculation time of 1 hour. If during business hours a calculation has been calculating for an hour, the calculation times out automatically. Depending on the calculation being performed, partial results may be available.

Error in GPU calculation

During the calculation, an unknown error has occurred. This may be due to an unexpected configuration of the specific calculation, or an internal error in the calculation infrastructure. Please contact support with a description of the calculation and its related settings to further investigate the issue.

Insufficient memory

An overlay's simulation model contains many data arrays to do the calculation on the GPUs. When this error occurs the total amount of data arrays needed to do the simulation does not fit in the GPU memory. This error is hardware limited and can only be resolved by creating a smaller dataset. It can be resolved in two ways: First increase the grid cell size (less cells means less memory). The second option is simplification of the simulation by for example using less result types or model option.

Prequel

When a Grid Overlay encounters an error, its results may not be valid. Any other Grid Overlay which uses that first Grid Overlay as a prequel will warn about that error in one of the prequels taking place. Subsequent Grid Overlays relying on that one will also report the error.
