Every BATCHLAS_* environment variable the library reads, captured once into batchlas::Settings, plus the programmatic override configure().
The environment is read once, on the first call to settings(). A knob whose call site uses one of the shared parsers in <batchlas/util/env.hh> is a typed field parsed by that same parser; a knob with a bespoke parser is an EnvValue (the raw string) and its parser stays at the call site, so every variable means exactly what it meant before this header existed. The user guide, with a field/variable/default table per group, is the "Configuration" section of docs/cpp-api.md.

Classes | |
| class | batchlas::EnvValue |
| A raw captured environment value, shaped like the std::getenv call it replaces. More... | |
| struct | batchlas::RoutingSettings |
| The route pins: BATCHLAS_<OP>_ROUTE, one raw string per op that selects a kernel. More... | |
| struct | batchlas::SelectionSettings |
| Which kernel or algorithm runs, for the knobs outside the route pins. More... | |
| struct | batchlas::GeometrySettings |
| Launch geometry, block widths, iteration counts and tuning thresholds. More... | |
| struct | batchlas::GeometrySettings::TuneSettings |
| The runtime overrides of include/batchlas/tuning_params.hh (BATCHLAS_TUNE_*). More... | |
| struct | batchlas::DiagnosticsSettings |
| Tracing, dumping, profiling and the opt-in checks. More... | |
| struct | batchlas::DiagnosticsSettings::DumpBandR1Settings |
| The BATCHLAS_DUMP_BANDR1_* band-reduction dump family. More... | |
| struct | batchlas::UnsafeSettings |
| The overrides that remove a guarantee: setting one can make a correct program crash, hang or silently compute wrong numbers. More... | |
| struct | batchlas::Settings |
| Everything BatchLAS reads from its environment, in one value. More... | |
