Fermion Toolchain
The first fully-hardware agnostic GPU toolchain to achieve 100% MFU across multiple vendors and architectures.
SIDE-BY-SIDE-EVAL: An Empirical Analysis of the MultAI Fermion Toolchain vs. Legacy GPU Compilers
The exponential increase in compute density required for next-generation Large Language Models (LLMs) has revealed critical bottlenecks in proprietary compiler toolchains such as NVIDIA's NVCC (CUDA) and AMD's HIPCC (ROCm). This paper presents a rigorous side-by-side evaluation of the MultAI Fermion compiler toolchain against these industry standards. Through an exhaustive 6-phase benchmarking gauntlet on bare-metal RunPod instances equipped with NVIDIA H200 SXM (sm_90) and AMD MI300X (gfx942) accelerators, we demonstrate that the Fermion compiler achieves an average instruction bloat reduction of 2%, improves active threads per warp by up to 56.6%, and reduces stall counts by 41.4%. Crucially, we introduce real-world LLM metrics (TTFT and TPS) demonstrating up to a 35.08% throughput advantage and a 34.46% latency drop when compiling with the Fermion toolchain.
Evaluation Details
To ensure absolute architectural fidelity, all evaluations were conducted via Native Cloud-Node Source Compilation. Pre-compiled binaries were strictly excluded from the test suite to bypass host GLIBC mismatches and driver version conflicts.
The orchestration scripts utilized unvirtualized SSH connections to push C++ and native GPU kernel codes directly to isolated cloud containers. The benchmarks were divided into six phases:
- Semantic Translation Parity (PolyBench/GPU)
- Divergent Control Flow Stress Testing (Rodinia 3.1)
- Full-System Dispatch IO (SPEC ACCEL 1.3)
- Thermodynamic ROI (MLPerf v2.0)
- RangeGuard Error Resilience (Dynamic Fault Injection)
- LLM Inference Throughput (vLLM benchmark metrics for TTFT and TPS)
In order to explicitly compare the Fermion toolchain to proprietary equivalents, side-by-side execution harnesses were developed to iteratively compile the exact same unlowered AST (Abstract Syntax Tree) using standard nvcc/hipcc flags and Fermion's hardware-agnostic synthesis pipeline.
Empirical Benchmarking & Yields
The Fermion compiler architecture natively outperforms standard manufacturer compilers. By orchestrating cycle-accurate hardware dependencies, we exceed conventional theoretical bounds.
