localmaxxing · hardware label: Intel Arc Pro B70
localmaxxing · notes: Quality-preserving Qwen3.6 27B Q4_0 GGUF tensor-split run on two Intel Arc Pro B70 32GB GPUs. Same Q4_0 weights and f16 KV cache, greedy decode, no speculative decode, no power-limit changes. Local patches add SYCL async cpy_tensor, Qwen recurrent split anchoring, and an experimental direct 2-GPU single-kernel F32 allreduce that peer-reads both partial tensors and writes the sum back to both devices. Low-level SYCL peer read/write stress test passed. Validated over 512 generated tokens, 3 repeats: samples 39.8517, 39.7809, 39.9148 tok/s. Previous quality-preserving Q4_0 TP2 result was 38.621 tok/s; single-B70 baseline was 24.723 tok/s.
