◆ pops_sf_mark()

void pops::field_solver::pops_sf_mark ( const char *  w )

inline

Writes the marker w to stderr (with flush) ONLY if pops_trace_sf(); no-op otherwise.

◆ pops_trace_sf()

bool pops::field_solver::pops_trace_sf ( )

inline

True if the DIAGNOSTIC trace of the solve_fields path is active (environment variable POPS_TRACE_SOLVE_FIELDS set).

Added for a CUDA device-crash diagnostic: writes to stderr with immediate flush to locate the last marker before a device crash. INERT by default: no effect on the outputs or on the numerics. Diagnostic KEPT (env-gated): useful for a future device crash.
