Data Read Timing Outputs

Following the query phase of reading a dataset, the next timing output which gets reported is the rest of the time it takes to read the dataset.

This time includes the step of creating a pre-processing data structure (when reading the grid) which AcuFieldView uses to quickly find the specific data it needs to create a particular surface or return a point probe call for example. The feature, DataGuideTM, lets you write this data structure to disk, and saves you the time of having to generate this structure each time you read the dataset. The time savings provided by not having to create the pre-process data structure can be anywhere from 2X (unstructured data) to 10X (structured data). This timing result plus the query time represents the total time to read the dataset. This timing result is returned at the Client, Controller and Worker levels of operation for the following dataset formats:

Surface Timing Outputs

Surface timing output has been limited to include Computational, Coordinate, Iso-, Boundary and XYZ Seed Plane surfaces. For Computational and Boundary surfaces (unstructured datasets only) specification of the surface geometry is explicitly defined. For the other surfaces types, AcuFieldView needs to determine which cells are actually part of the surface, and how they are connected. In some instances, this time can be significant, and this has been broken out as a Phase 1 timing output. The time to complete the remaining tasks for the surface are grouped into the Phase 2 timing output. In some cases, the Phase 1 timing output will be zero. This will occur when you change the scalar on an existing surface. These timing results are returned at the Client, Controller and Worker levels of operation:
