How to build and run GPU targets under Buck in fbcode. Use when invoking buck2 run / buck2 build for any GPU benchmark, test, or kernel — selecting the GPU architecture and CUDA version, using @mode/opt and the beta Triton modifier, passing environment…

Run the sched2tlx perf/correctness harness over the modulo-scheduling example corpus (case1-9: GEMM, persistent GEMM, FA fwd/bwd, addmm+bias, LayerNorm, wgrad+bias, multiphase GEMM, scaled_mm). Use when the user asks to benchmark generated-vs-handwritten…

Produce a structured barrier report for AutoWS (automatic warp specialization) IR. Use when the user wants to visualize, audit, or debug barrier usage across warp-specialized partitions, or when debugging a GPU kernel hang (deadlock). For hangs, first dump IR…

Run NVIDIA compute-sanitizer (memcheck, racecheck, initcheck, synccheck) against a Triton/TLX kernel to find runtime memory and synchronization bugs. Use when a kernel produces wrong results, crashes with an illegal/misaligned access, or is suspected of a…

Run TLX kernel performance benchmarks on Hopper, Blackwell, and AMD (gfx950/CDNA4, gfx1250) GPUs. Use when user asks to benchmark, profile, or measure performance of any TLX kernel (GEMM, Flash Attention, addmm+GLU, IKBO variants). Handles GPU selection,…

Test and run TLX-AMD tutorial kernels (gfx950/CDNA4 and gfx1250) and understand their CI. Use when working on AMD TLX tutorial kernels — GEMM (warp-pipeline, LDS-pipelined, TDM, MXFP), Flash Attention (simple, prefetch, persistent), addmm+GLU, or IKBO (FA,…

Author Triton kernels with automatic warp specialization (AutoWS). Use when writing new AutoWS kernels, adding warp_specialize=True to tl.range loops, choosing tl.range kwargs and JIT options, debugging why WS was not applied, or structuring a kernel to work…

Design and run Triton TTGIR debugging ablations using ir_override. Use when reducing a provided or dumped TTGIR, trying user-provided or agent-generated ablation/oblation ideas, updating a test harness around ir_override, or preserving a compile/runtime…

Recover from GPU-busy / GPU-unavailable failures. Use when a command (pytest, python, a TLX/Triton kernel run, a benchmark) fails with errors indicating the GPU is busy, out of memory, or unavailable — e.g. "CUDA error: out of memory", "all CUDA-capable…

TLX DSL API reference for low-level GPU primitives. Use when writing or modifying TLX kernel code that uses barriers (mbarrier, named barriers), memory allocation (local_alloc, SMEM, TMEM), TMA operations, warp specialization (async_tasks, async_task), CLC…

Use when working on fence-related compiler passes, TMA store lowering, proxy fence insertion, investigating missing or spurious fences, or debugging correctness issues in TLX kernels that use tlx.async_descriptor_store or MMA operations.

Run autoWS (automatic warp specialization) correctness tests. Use when working on autoWS compiler code — files under WarpSpecialization/, partition scheduling, warp_specialize ops, WSCodePartition, WSDataPartition, WSTaskPartition, WSMemoryPlanner, or related…
لغة النص الأصلي: الإنجليزية
Consult and maintain AutoWS documentation. Use BEFORE exploring AutoWS source code — when investigating, planning, or modifying files under WarpSpecialization/, partition scheduling, warp_specialize ops, WSCodePartition, WSDataPartition, WSTaskPartition,…

Diagnose CUDA "illegal instruction" / kernel crashes on Triton kernels that reference to TMA loads or stores (`make_tensor_descriptor`, `TensorDescriptor`, `descriptor.load`, `descriptor.store`, `tl.async_descriptor_load`, async TMA copies) as the source code…
لغة النص الأصلي: الإنجليزية
Debug Triton compilation by dumping IR at each stage (TTIR, TTGIR, LLVM, PTX). Use when investigating compilation failures, kernel performance, register spills, or when user asks to inspect IR output. Covers TRITON_KERNEL_DUMP, MLIR_ENABLE_DUMP,…
