Abstract
The last decade has seen a significant growth in the financial industry. The recent widespread use of Internet technology has increased the accessibility of the general population to financial data, thereby increasing the average portfolio size. This increase, compounded by the need for accurate real-time results, has led to a rising demand for faster risk simulations. Often, accurately pricing widespread instruments, such as Collateralized Debt Obligations (CDOs), can take excessively long due to their multifactor assets dependency. We present a hardware implementation for a MultiFactor Gaussian Copula (MFGC) CDO pricing algorithm. Through a detailed benchmark exploration we demonstrate how reconfigurable hardware could be used to exploit fine-grain parallelism. Our results show that our implementation mapped onto a Xilinx Virtex 5 (XC5VSX50T) FPGA is over 71 times faster than corresponding software running on a single core 3.4 GHz Intel Xeon processor.

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
