The reason for the unit tests failing was just an undefined event? I feel like the tests shouldn't fail in that case, just not capture the unknown event? |

Replacing the magic number is a NFC right? It's just now we have a named variable in the HIP headers?

NFC? The hip headers are included with Triton so there should not be any issues as this is a drop in replacement as the enum maps to the same number.

NFC - no functional change.
It's for an upcoming docker change that bumps ROCm version; see the discussion here #5230 (comment) |

Right, I get that but I'm trying to figure out "what" specifically changes when we bump the ROCm version. Did we change the HIP event which tracks graph launches? |

Update Update Update Update Update Use pytest' `tmp_path` in `test_irsource.py` (#5145) Signed-off-by: Anatoly Myachev <[email protected]> [TEST] Make mixed matmul test deterministic (#5151) This prevents surprises when some value may go above the tolerance threshold Fix `gtest_discover_tests` timeout argument (#5149) `gtest_discover_tests` runs the built unittest executable to create a distinct CMake target for every individual unittest in each executable. However, this was previously noted to time out on MacOS frequently (because MacOS scans newly built executables for viruses, or something...) but the timeout argument was incorrectly specified. [Triton] Remove upstream bug workaround (NFC) (#5152) Upstream handling of splatted bools in `DenseElementsAttr` was fixed, so the workaround can be removed when lowering `arith.constant` to TritonGPU. Co-authored-by: peterbell10 <[email protected]> [Triton] Generate local MLIR reproducers when possible (#5155) By setting a reproducer path, the pass manager will dump a standard MLIR reproducer before each pass manager invocation. This PR also enables additional local crash reproducer generation (to the same path set through the env var), which tries to narrow down the specific pass that failed, if the pass pipeline fails at any point. Revert "[AMD][Pipeliner] Improve clustering and add prefetch (#4881)" (#5157) This reverts commit cc25374 due to perf regressions. [IR] Add typing for tensor descriptor types (#5147) Currently tensor descriptors are just typed as `!tt.ptr<i8>` which is exposing the assumption it's using a TMA descriptor. This changes it to a custom type `!tt.tensordesc<tensor<...>>` which is lowered to a pointer type in the LLVM IR. I also add two new IR Ops which are used to cast between pointers and tensordesc objects. ```mlir tt.reinterpret_tensor_descriptor %ptr : !tt.ptr<i8> to !tt.tensordesc<...> triton_nvidia_gpu.tensor_desc_to_tma_ptr %desc : !tt.tensordesc<...> -> !tt.ptr<i8> ``` Really both of these should be nvidia-specific but the first is exposed in the triton IR to keep support for the by-value TMA descriptor API around while we figure out if it's possible to update to the new style. Load backend dialects in `IRSource` to make sure `parse_mlir_module` works for third_party backends (#5146) The changes from #4924 do not take into account the situation when `ttgir` level contains dialects defined in third_party plugins (at least that's my understanding). I'd also like to point out that the second use of `parse_mlir_module` function (via `parse` function call) happens after the dialects are loaded for the backend as well, which is why I thought my changes make sense. I hope this implementation will suit Triton, or maybe one can suggest other options. --------- Signed-off-by: Anatoly Myachev <[email protected]> [BACKEND][NVIDIA] Add DotOp Hoisting Pass for WGMMA and Add Lowering for SMEM-to-MMAv3 DotOp Copy (#5003) Hopper has two kinds of WGMMAs, "SS" (both operands in shmem) and "RS" (LHS operand A in registers). In cases where we apply elementwise operations on A before WGMMA, Triton previously will copy A from global memory (GMEM) into registers (RF), perform the elementwise ops, and then copy to shared memory (SMEM) to perform SS WGMMA. This PR adds an optimization for the case above to use RS GEMM. This requires the following changes: - In TritonGPU OptimizeDotOperands pass, add optimizations to change SS GEMM into RS GEMM. - Add TritonGPU -> LLVM lowering for copying from SMEM to RF in MMA v3 dotOperand layout. NOTE: This may not see perf gain, and may even see perf loss, for certain shapes (e.g. small-K), and additional optimizations are in a separate [PR](openxla#19) (still more optimizations are WIP). Please advise on the merging strategy. Restore the CentOS 7 build (#5158) We likely need it for the PyTorch 2.6 release [BACKEND] Add folder for `addptr(ptr, 0) -> ptr` (#5166) I noticed this rather obvious pattern was missing. It might come up for example if you have an expression like: ```python ptrs = ptr + y_stride * tl.arange(0, YBLOCK)[:, None] ``` and the `YBLOCK` is set to 1 during autotuning. [TritonGPU] Fix incorrect mask operand used in for loop pipeliner (#5161) When the OOB values for a `tt.load` are non-zero, the for loop pipeliner needs to generate an `arith.select` to mask the loaded values with the default OOB value. However, if the load memory requires a layout change, the wrong mask operand was being passed to the `arith.select`, causing a shape mismatch. The fix is to just use the same mask operand of the origianl `tt.load` op. Fixes #4739 [BACKEND] Cleanup redundant broadcast combine pattern (#5167) Summary of changes: - Remove `broadcast(cst) -> cst` from the triton-combine pass since it's redundant with the existing folder. - Reorder the triton-combine pass to come after the canonicalize pass, to simplify pattern matching - Cleanup patterns in triton-reorder-broadcast that called `Op::canonicalize` in favor of `Op::getCanonicalizationPatterns`. [AMD] NFC: Drop duplicated moveUpTranspose (#5168) It was duplicated due to resolving merge conflicts.

[AMD] Refactor instruction scheduling hints (#5144) - Renamed instruction scheduling variants - Enabled `buffer-ops` for `local-prefetch` - Added documentation regarding current variants --------- Co-authored-by: Lei Zhang <[email protected]> [AMD] Enable mixed precision matmul test (#5177) This commit enables mixed precision matmul test for AMD backend. For FP8 E4M3, we test `fp8e4m3fnuz` given that's natively supported on MI300 series. Update to llvm/llvm-project@bd9145c8c213 (#5180) This pulls in llvm/llvm-project@bd9145c8c213 to enable ASan on AMD backend. [AMD] Implement RepOrder for AMD MMA layouts (#5126) Implement RepOrder methods for MFMA and WMMA layouts. Both layouts have row major rep layout. Also, isTranspose flag in MFMA layout does not affect RepOrder, meaning RepOrder is row major in both cases. Co-authored-by: Ognjen Plavsic <[email protected]> [BACKEND] Fix ProgramPoint passing in AxisInfoAnalysis (#5181) Fixes #5122. The `ProgramPoint` [here](https://github.com/triton-lang/triton/blob/0bd30a2f3192204c5a50d5ffde27ad8493f6c026/lib/Analysis/AxisInfo.cpp#L1087) is created on the stack. Then its address is [passed](https://github.com/triton-lang/triton/blob/0bd30a2f3192204c5a50d5ffde27ad8493f6c026/lib/Analysis/AxisInfo.cpp#L1088-L1089) to the MLIR `SparseAnalysis` code, where it is [added as a dependency](https://github.com/llvm/llvm-project/blob/33ff9e43b4c5bdc3da31c6b11ad51d35a69bec5f/mlir/lib/Analysis/DataFlow/SparseAnalysis.cpp#L311) and later [dereferenced](https://github.com/llvm/llvm-project/blob/33ff9e43b4c5bdc3da31c6b11ad51d35a69bec5f/mlir/lib/Analysis/DataFlow/SparseAnalysis.cpp#L90). By the time the `ProramPoint` is dereferenced in the `AbstractSparseForwardDataFlowAnalysis::visit`, the `AxisInfoAnalysis::visitForOpInductionVar` will have finished and the `ProgramPoint` stack variable destroyed. This leads to a segfault (which can be reproed on the base rev with the lit test added in this PR). The code modified in this PR was originally added in #4927, in conjunction with updating the `llvm-project` hash to `b5cc222d7429`. However, as noted in llvm/llvm-project#110344 (the `llvm-project` PR that has made the refactoring prompting the `AxisInfo.cpp` change in #4927): > For dense forward data-flow analysis and other analysis (except dense backward data-flow analysis), the program point corresponding to the original operation can be obtained by `getProgramPointAfter(op)` As the `AxisInfoAnalysis` (in Triton) inherits from `SparseForwardDataFlowAnalysis` (in MLIR), in this PR we follow the above which resolves the segfault issue (as the `ProgramPoint` is now stored in the instance-level state of the pass). P.S. The lit test added in this PR is not exactly minimal. However, I did my best to minimize it starting from the 400-line repro TTGIR in [INTERPRETER] Fix argument passing for internal parameters in function declarations (#5169) [NFC] Use reference instead of copies in few places (#5118) Apply fixes suggested by coverity static analysis. Signed-off-by: Anatoly Myachev <[email protected]> [BACKEND] Add missing precondition in optimize acc init (#5184) We need scalar select to be able to do this optimization. [BACKEND] Fix accumulator init optimization for integer matmuls (#5192) [AMD][Pipeliner] Reland "Improve clustering and add prefetch" (#5175) This unreverts commit 38c6284 to reland #4881 with the following fixes: * Still keep `scheduleGlobalLoadLocalStore` as original--it turns to be not totally ready to replace yet. Further iteration on it needed. * Turn on `TRITON_HIP_STREAM_PREFETCH` if the instruction scheduling variant is `local-prefetch`, given it's needed there. --------- Co-authored-by: Lei Zhang <[email protected]> [AMD] Define an extract slice operation (#4804) This commit introduces an extract_slice operation for AMD backend to enable extracting slice of a tensor in registers without data exchange. It enables breaking down large tiles of tensors into smaller ones for better instruction interleaving and scheduling. This can be useful for hiding global memory latency when a global load/store can be efficiently split into several loads/stores to be overlapped with compute fo attention. [BACKEND] Fix getElemsPerThread for mmav3 dot operand (#5189) In mmav3 case the number of elements per threads should be independent of the element type, we should only consider kWidth. TODO: it should also be true for MMAv2 but the logic is a bit more complicated. Also enable larger block_m in mixed mode tests to exercise MMAv3 case [INTERPRETER][NFC] Rename `tensor_shape` -> `block_shape` in interpreter (#5195) `tensor_shape` is a confusing name and doesn't match block pointer's semantic. `block_shape` is much clearer. [LAYOUTS] Implement LL conversion for DotOperand(Hopper) (#5193) We also rewrite the way we implement DotOperand(Ampere) and mma Ampere to promote code reusing. I also started using what I believe is a rather compact pattern to write these things, where you first call `identiyND` with the `repOrder`, which gives you an LL with the dims in the correct order, and then you construct the final layout by specifying the tiles by multiplying `identity1D` maps. Using this allowed me to heavily simplify the handling of the `warps` of `DotOperand` which used to be a tad messy. Update README.md to remove triton conference (#5198) It happened two months ago [PROTON] Add `proton.state` utility (#5110) `state` is different from `scope` in several ways: 1. State is not recursive; each operation can have only a single state. Inner most state will overwrite the outer most state. 2. A states is a suffix, meaning that the original call path will append a state above the name of each kernel. 3. State is compatible with both Python and shadow contexts. [CI] remove unused inductor workflows (#5073) These tests have completely offloaded torch inductor tests to Meta a few months ago. They are currently disabled on GitHub. Signed-off-by: Sébastien Han <[email protected]> [INTERPRETER] Fix lower bound check for block pointers (#5201) We forgot to check `offset >= 0` previously. Now that it should match the semantic in the GPU backend https://github.com/triton-lang/triton/blob/7bce3613755e26953518962d02315dfd343dc50c/lib/Dialect/Triton/Transforms/RewriteTensorPointer.cpp#L136 [IR] Remove memdesc from `tt.trans` and implements `ttg.memdesc_trans` (#5194) [LLs] [BE] Simplify identityND (#5199) The auxiliary function `identityND` used to take an `order` parameter, that comes from triton, and a set of dimensions. Now, the order in triton is defined wrt. `dim0..dim<rank-1>`, so the dimension arg was redundant. This was quite confusing. We see that in all the uses of `identiyND`, we would pass the canonical dimensions, other than in one that we simply remove as it was not necessary. We remove the dims arg and simply return a layout with output dims `dim0..dim<rank-1>`. [MXFP] Fix packing for mxfp4 type (#5197) When packing we should have element 0 in the lower bits, until this PR it was in higher bits. [LAYOUTS] Unify the implementation of getShapePerCTA (#5183) We unify it and simplify its API (it was taking an unused `shape` parameter). While doing this, we found that the previous implementation was incorrect at least for `AMDWmmaEncodingAttr`, as this layout was using the shape parameter. Interestingly enough the doc in the header file for this function noted that the function is indeed independent of the tensor shape, even though the function does take a shape as an input! https://github.com/triton-lang/triton/blob/0bd30a2f3192204c5a50d5ffde27ad8493f6c026/include/triton/Dialect/TritonGPU/IR/Dialect.h#L113-L114 [BACKEND] Use the LL API to replace the using of legacy layout attribute API. (#5196) The util function `getDistributedLayoutStr` uses the `DistributedLayout` attribute interface, which is not flexible for third-party extensions. Use the `getInDimSize` of the `LinearLayout`, which is better since the legacy layout has been converted to the `LinearLayout`. There is no new test case since it is only a change in API usage. [CI] Fix ccache cache restoration to improve build times (#5202) This improves a warm-cache macOS build from ~25 mins to 2 mins. [CI] Fix `du` failling if cache restore fails (#5206) Follow up to #5202 It's currently failing with the error ``` du: /Users/runner/.triton/**: No such file or directory Error: Process completed with exit code 1. ``` which happens because even though the `.triton` directory exists, it is empty. This instead uses du on `.triton` with a depth of 1. [BACKEND][LAYOUT] Use LL for AMDMfma related layout conversions (#5210) [BUILD] Add option to limit number of parallel link jobs (#5212) [CI] Fix cache not saving (#5213) 1. [CI] Fix cache not saving Re-using the output of the cache restore step was recommended by the `actons/cache` docs, but it doesn't work here because we actually start from a clean cache when we run save so there is no output available to read. The annoyances of testing in the PR but main being a different environment. 2. Bump macOS timeout [LAYOUTS] Implement IR support for LinearLayouts (#5170) We also exercise this in scale_dot, where we enable support for warps of arbitrary shape (before we just allowed `[num_warps, 1]`). With this infra in place, it should be rather easy to move from the legacy layouts to using LLs to represent all of our layouts. Something I'm concerned about is the amount of recomputation that happens when calling methods like `getSizePerThread` and the like, where we keep recomputing the result. There might be an optimisation opportunity here where we cache the result of all these functions. We choose the IR representation of an LL via its canonical form + a `repOrder` for several reasons: - It's generally more compact - It's easier to CSE, so it's easier to see when two layouts are in fact the same. - A technical reason: the `toLinearLayout` function returns a tensor with dimensions `dim0, ..., dim<rank-1>`, in other words, it "forgets" the repetition order. Without the repetition order, we cannot recover the tile size of the argument. In particular, we cannot recover `getSizePerThread`. There is an argument to be made about whether `getSizePerThread` is useful on its own, or whether it is `getElemsPerThread` the real useful abstraction here, but for now, we keep both for BC. [CI] Run tests when CI is manually triggered (#5216) Currently you can manually call a workflow dispatch, but it won't actually run the tests because the variable enable_integration isn't set. [PROTON] Introduce the Proton dialect as a third-party plugin for intra-kernel perf tooling (#5119) This PR introduces the `Proton Dialect` to enable intra kernel profiling and tooling for Triton. As a third-party dialect, it serves as the building blocks to create 3rd-party perf tools (e.g., profilers, analysis, modeling) for Triton compiler developers in a compiler-centric way, such as an intra-kernel latency profiler to understand software pipelining, warp specialization, and CTA fine-grained orchestration (e.g., cuda core, tensor core, TMA). Future developments would integrate this dialect with the existing Proton backend profiling infrastructure to make it a powerful and general perf tool utility. As a first step, this PR adds some basic boilerplate code and mechanics, and the `proton.record` op for the `Proton Dialect`. --------- Co-authored-by: Yuanwei Fang <[email protected]> Co-authored-by: Keren Zhou <[email protected]> [DRAFT] Completely remove `MemDesc` from the Triton dialect (#5208) After this PR, `MemDesc` will be a type only in the TritonGPU dialect, as will the `TensorOrMemDesc` interface.

On top of this, it implements a simple caching system for this step based on just the block size. As noted in #4739, this caching is incorrect, because it's also not keyed on the `num_stages` constexpr argument or the shapes of the tensors. Since triton already has its own JIT compilation cache, and this caching bit is not really relevant to the tutorial, just remove it to get rid of the footgun.

[BACKEND] Fix inline asm bug for multiple packed <32bit output (#5273) Resolves #5272 - Fixes logic for walking result struct from LLVM InlineAsm in case of multiple sub-32bit results - Adds lit test [NVIDIA][Backend] Add CoalesceAsyncCopy Pass for in-DotOpEnc Upcasting (#5222) This is a follow-up to the dotOp hoisting optimization for WGMMA (MMAv3). See #5003 (comment) In short, when upcasting operand A in registers prior to WGMMA and when pipelining is enabled, `AsyncCopyGLobalToLocal`'s src gmem blocked encoding will have `sizePerThread` > smem view's `vec` (along the contiguous dimension). This will resulting in multiple `cp.async` instructions being generated for a contiguous global data segment, resulting in uncoalesced loads. This was previously confirmed in ncu. See above comment for an example. I've added a generalized fix in a new pass after the pipeliner. I've reused the logic in the LLVM lowering for `AsyncCopyGlobalToLocal` to calculate the max contiguous copy size. I compare that to the blockEnc's `sizePerThread` along the inner (contiguous) dimension. If the former is less than latter, I set the latter to former. When A is k-major, can verify a small perf improvement and that ncu no longer reports uncoalesced loads. When A is m-major, this pass is a no-op because `copy size == sizePerThread == 16` ptal, thanks @ThomasRaoux [Triton] Add `tl.gather` with a naive codegen implementation (#5262) This PR adds a `tl.gather` builtin that implements a local gather along a single axis, with semantics matching `torch.gather`. `tl.gather` generates a `tt.gather` op, which is piped through the compiler mostly untouched at the moment, since the codegen is very naive. The `tt.gather` is implemented by writing the source tensor into shared memory and then performing a gather out of shared memory, thus it requires scratch space to be allocated. In a follow-up, I will implement an optimized layout rule for the op that ensures the gather axis fits into a single warp, allowing the gather to be implemented using warp shuffles. There are other avenues for optimization as well: `tt.gather(tt.load)` where the load only has one use can be lowered into a DMA from global memory to shared, and then gather directly from shared.

(considering that the project declares support for the c++17 standard). I discovered this while trying to compile proton using MSVC. It looked like this: `\CuptiPCSampling.cpp(18): error C7555: use of designated initializers requires at least '/std:c++20'`.

Latency assignment is a transformation that analyzes the loop and based on the requested number of stages it assigns "latencies" to the ops that are going to be converted to async ops by the pipeliner. Latencies are expressed in terms of number of iterations of the loop and can be thought as per-operation num_stages. Scheduling transformation takes these latencies and builds a pipeliner schedule based on it. The process of building a schedule was slightly rewritten to simplify the code and cleanup the logic that was no longer needed after recent refactoring. Breaking down the schedule into latency assignment and proper scheduling has number of purposes: 1. Code became more modular, with cleaner interfaces that helps with maintanance 2. Both parts can be tested in separation, I have added lit tests for both pieces. We can finally test our pipeliner infrastructure in manageable chunks 3. It opens up opportunity to expose per-op "latencies" to the frontend, enabling creating user-defined schedules right from the language level Next step in the cleanup process is to clearly separate lowering and pipelining phases.
