Abstract
OpenCL pipes offer a powerful construct for synthesizing multi-kernel FPGA applications with inter-kernel communication dependencies. The communication discipline between the FPGA kernels is restricted to producer-consumer style patterns supported with on-chip FPGA FIFOs. While this provides few restrictions on the usage, the OpenCL compiler is unable to provide guarantees on buffering capacity or schedulability of the connected kernels. Without these guarantees, an OpenCL developer may over-provision hardware resources or assume pessimistic timing during scheduling. We propose imposing a communication discipline inspired from models of computation (e.g.Ptolemy) such as synchronous dataflow (SDF), and bulk synchronous (BSP). These models offer a restricted subset of communication patterns that enable implementation tradeoffs and deliver performance and resource guarantees. This is useful for OpenCL developers operating within the constraints of the FPGA device. We provide a preliminary analysis of our proposal and sketch programmer and compiler responsibilities that would be needed for integrating these features into the FPGA OpenCL environment.

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
