Abstract
We introduce the Stupid Barrier Tricks (SBT) library for on-line debugging and performance monitoring of shared-memory parallel programs. Single-program-multiple-data (SPMD) programs often use barriers to synchronize threads of execution and to delimit the start and end of different phases of computation. Through the novel (and simple) named barriers construct, dynamic performance warnings, and integration with lightweight performance counter libraries, SBT helps programmers localize deadlocks and performance bottlenecks in their programs. SBT is a portable library that currently supports both POSIX threads and SGI Irix sproc threads. SBT also supports both the PCL and Irix libperfex performance counter libraries. For production runs, the SBT overheads can be eliminated using conditional compilation.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
